Many xp system can enable the guest network access, the failure to resolve as follows:
Why is the opening of the guest still can not visit
1. Default case, xp disabled guest account
2. Default circumstances, xp local security policy prohibits users from the guest network access
3. Default circumstances, xp local security strategy - assigned user rights, "Air password users can only console landing" is opened, that is to say, empty password of any account not only from the local network access Landing, guest default password space
Therefore, if the need to use the guest user access xp so, to carry out the above three settings: the opening guest, modify security policy allows guest visit from the network, disable the three inside the security strategy or to the guest and a password.
Xp the visit, log dialog user name is gray, has always been the guest users can not enter other user accounts.
This is why security strategy in mischief (management tool - the local security strategy - security options - "network access: the local account sharing and security model") See attached map.
By default under, xp the visits are "guests only" approach, then you access it, of course, the guest can not be fixed for the importation of the other user accounts.
Therefore, the visit xp the simplest way is: no opening guest, only to amend the above security strategy for the "classic" on the line. Other system access xp can enter their account information.
Access XP to share a solution to the problem
Vista users Myoho shield activated tips skills
The article title, only so that "will Skills" is considered from two aspects: first, many are not very familiar with Windows Vista's User installing Vista, do not enter a serial number (or enter a not authorized serial number); section Second, as many netizens do not know that Microsoft's "Genuine Advantage" What does it mean, took part in the "services" after the discovery system into a "genuine non-authorized" the.
These two operations will bring about "hidden dangers", that is, the system will continue to prompt similar to "XXX days left activated," the news. If you do not want to activate this time, but want to experience more days of Vista, to facilitate future whether to continue using Vista, you can activate a message to shield the way to shake off problems. Methods of operation are as follows:
Operation of the registry, then start to the following branches: HKEY_LOCAL_MACHINESOFTWAREmicrosoft
Windows NTCurrentVersionSLActivation, double-click on the right side window in the "Manual", in the pop-up dialog will be its value from "0" to "1"
After the set, exit the registry editor. Since then, the "computer" attribute (or restart the welcome center) at the bottom of the Windows activation of the system will not have activation notice exist, and only shows the current assessment of the number of days remaining.
Do not want to start XP, such as the speed of the speed!
Computer users are often heard complaining about this: how self-inspection after I opened the computer screen is black, only half a day to the XP interface appears » I entered the computer systems doing so slow » Scroll bar are also to the more than 10 laps into the system can not. Why is my XP desktop appears after a few minutes click on any of the procedures have no reaction » These problems can be summed up as Windows XP slow start. How can we do to accelerate the start-up rate system? »
XP slow start to solve the problem, we must first understand the system start-up process. Windows XP activation process can be broadly classified into five steps: first step, the pre-start: First of all computer power for self-inspection by the BIOS (basic input output system that is) scanning hardware and complete the basic hardware configuration, and then drive to read the MBR (Master boot record) check your hard disk partition table to determine the guiding Division, and will guide the district on the operating system boot sector in the implementation of the redeployment of memory, here is the implementation of NTLDR (operating system to load) document. The second step to start: First and only to, NTLDR is from the processor model will be converted to 32 protected mode. BOOT.INI and then read the document. The third step is. Loading kernel: to guide the process began loading XP core NTOSKRNL.EXE. This file is in Windows2000/XP installation folder under the SYSTEM32 folder. Subsequently, the Hardware Abstraction Layer (HAL) was to guide the process of loading, the completion of this step. The fourth step, the initial core: core complete initialization, NTLDR will be handed over to the control of the core Windows2000/XP, which began loading device drivers and initialization and start WIN32 subsystem and WINDOWSXP services. Step 5 is the user login, login, XP will continue to configure network equipment and user environment. Finally, accompanied by a system reboot music and we are familiar with the desktop, Windows XP start the long process was finally completed.
Understanding of the XP activation process, we can in a targeted manner to take measures to expedite the start of speed.
1, does not prohibit use of peripherals
Through the process before the start of the understanding we know, XP will be automatically activated in the scanning hardware, so if the WinXP disable some peripherals, system can effectively reduce the need to start the redeployment of the number of peripheral drivers, so as to speed up The start-up system speed. If your computer has no USB devices, in the "Device Manager - Universal Serial Bus controllers" will disable all USB devices. This method allows you to the XP start-up time reduced by about 15 seconds. Secondly, if you do not have multiple hard drives, can also ban certain IDE equipment to speed up the launch speed. Is: Right-click on the "My Computer - Properties", then click the "hardware" and then click on "Device Manager", which opened in the "IDE ATA / PATA controller" (a slight difference between different chips), and then separately to main And secondary IDE channel, select "Advanced Settings", located here, "the current transmission" as "not applicable" a (This is the idle channel corresponding to the IDE), this will be the "equipment type" is set to "Nil", can be identified. In addition to Note: Due to the default system will automatically read the drive, the drive will start at the test, if placed in the CD-ROM drive, it will automatically read, if a multimedia CD-ROM so readers will spend a longer time , To extend the same computer's start-up time. Therefore, we usually use the proposed recall timely End CD taken out.
2, to reduce the load at startup procedures
Many people probably have this feeling: XP start-up speed of the initial installation of the system is still relatively fast, but with the installation of the software continue to increase, the rate will start increasing slowly. This is because many of its own software to increase in the commencement of the proceedings, so that the required start-up operation and greatly reduce the launch speed, but also occupy a large amount of system resources. For some procedures so that we can through the System Configuration Utility Msconfig from the start they will exclude groups. Select "Start" menu in the "Run" commands, "Run" dialog box, type "Msconfig", will return after the pop-up "system configuration utility" dialog box, select one of the "start" tab, the Tab of the system listed in the commencement of the project and the source of loading, carefully looking at each project the need for automatic loading, or remove items before the box, loading the less the item, the faster start . In addition to the proposed reservation input method (for the commencement of the project ctfmon) and antivirus monitoring procedures (such as RavTask), the other to prohibit all his run automatically at startup.
Upgrade Win XP operating speed 100 percent IX skills
The use of XP in the process, the system will speed with the passage of time more and more slow, and some friends could think of heavy equipment systems, but heavy equipment, so many have to re-install the application software, how to not install System under the premise of upgrading the XP operating speed? » As long as you regard the operation as the following nine, I believe your XP will be re-high-speed operation.
1, speed up the switching speed
In Windows XP shutdown, the system will send a message to the operational procedures and the remote server, tell them to close the system, and wait for the response received after the system began shutting down. Speed up the start-up speed, you can set up automatic tasks, first of all to find HKEY_CURRENT_USERControl PanelDesktop, the AutoEndTasks the key is set to 1, then the branches under a "HungAppTimeout", its value to "4000 (or less), The default is 50,000 and finally to find HKEY_LOCAL_MACHINESystemCurrentControlSetControl, similar WaitToKillServiceTimeout set to "4000"; through this set off at a much faster.
2, increased broadband speeds
Professional version of Windows XP by default retained 20 percent of the bandwidth, in fact, that our individual users is no effect. In particular, it is not idle if the full use of it.
"Start → run" enter gpedit.msc, open the Group Policy Editor. Find "computer configuration management templates → → network → QoS packet scheduling procedures", choose the right "to retain bandwidth restrictions," select "Properties" to open the bandwidth limitations may retain the properties dialog, select the "opening" and the original " 20 "to" 0 ", the release of such a reservation of bandwidth.
3, optimizing the Internet neighbors
Windows XP neighbors in the use of the Internet, the system will search their shared directories and can be used as network printers and plans to share the tasks of the plan and network-related tasks before the show, and this will obviously slow the speed of many. These features not much use to us, it can be removed. In the Registry Editor find HKEY_LOCAL_MACHINEsofewareMicrosoftWindowsCurrent VersionExploreRemoteComputerNameSpace, delete the (printer) and (D6277990-4C6A-11CF8D87-00AA0060F5BF) (planned tasks), restart the computer, another visit to the Internet neighbors, you will find a lot faster.
4, speed up the launch rate
To speed up the Windows XP start-up speed. May amend the registry to achieve the purpose of the registry editor, find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters, the right to find EnablePrefetcher primary key to its default value of 3 to 1, this time rolling scroll will be reduced;
5, shut down automatically stop response procedures
Sometimes, XP will prompt you to stop responding to certain procedures, Henfan, by modifying the registry so we can turn itself off, the characters will be in HKEY_CURRENT_USERControl PanelDesktop-AutoEndTasks is the numerical value of the data changed to 1, or start to re-write-off.
6, speed up the menu display speed
In order to speed up the menu display speed, we can follow the approach set: we can find in HKEY_CURRENT_USERControl PanelDesktop "MenuShowDelay" the main key to its value to "0" can reach speed up the menu display speed results.
7, was not cleared in memory of DLL files
In the registry HKKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion, one of the increase in Explorer AlwaysUnloadDLL, default to 1. Note: by default is set to 0 on behalf disable this feature.
8, to speed up pre-reading ability to improve the start-up speed
Windows XP pre-reading system set up to improve the speed, speed up the start-up speed. Here are the ways to further modify the use of CPU efficiency: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManagerMemoryManagement], PrefetchParameters in the right window, the numerical data are as follows EnablePrefetcher changes, such as the use of PIII 800MHz CPU over the proposed changes to the numerical data for 4 or 5, or proposed to retain the numerical Data for the default value is 3.
9, reduce the load on commencement of the project
Many applications in the installation will start Zizuozhuzhang added to the group system, each system will automatically start running, not only to extend the start time and started after the completion of system resources have been consumed!
Start "system configuration utility," in the "start" of the system listed in the commencement of the project and the source of loading, check carefully whether you need it automatically load, or remove items before the box, loading the item The less, the speed and start the sooner. The need to re-start to enter into force .
Revelation Windows Vista Ultimate search Principle
How do you find two seconds in the computer storage of any resources? ?- Local search through the Vista!
Vista system used by the readers will know that its search function is very powerful, and under the previous Windows search function compared to the speed of a qualitative leap. Microsoft is how to speed up the search to achieve this objective? «Today, we will accelerate the search for the principles we all start on Vista system of" Lightning search "feature.
Vista search of past lives, Many Masters
In Windows Vista system released before its own search function is very bad, not only inconvenient to operate, and search and search speed of the types of information are far from meeting customer needs, many Windows users have abandoned system comes with a search function, in turn The use of other manufacturers released by the local search tool.
To make up for this flaw, Microsoft has also been efforts, and launched in 2003 based on the WinFS (Windows File Search) of the Windows Desktop Search tool. Windows Desktop Search is replaced by a WindowsXP based on the start menu search tool, providing greater functionality and convenience of search based on the task bar. This WDS also known as the Vista search prototype, it has no built-in Windows 2003 and WindowsXP, is only a tool in the form of release.
With the release of Vista, Microsoft Windows Desktop Search will be improved built into the Vista system, so as to completely replace the traditional search function. At this point Vista system to search for a formal new form, from behind the scenes to the stage in the Vista search speed, functionality and ease of use, to show significant upgrade.
Lightning speed of the search
Used WindowsXP users will know in a 80 GB hard drive search files, I am afraid, take a few minutes or even longer to find a result. But Vista search ingenious solution to the problem of slow such search, enter the keyword search, click on "Search" button, can immediately show results, real, "found that from the" quick search purposes.
Also in the Vista system use the search function is very simple, not in the "Start" menu in the search to find specialized items, open the "Start" menu can be seen directly after the search keyword input field presence.
The power of indexing
Why, then, Vista's search system in such a quick pace? The main reason is that it uses a google desktop search improve search speed of the same principles of the technology, known as the Indexing Service index services, but Vista search can be customized by the user The index, based on which include documents, which directory, which disk and which format of the document. Vista search is a dynamic real-time updates, so we do not have to worry about document changes will cause an error search problems. For example: users of a file from C to D-disk clip, the index is automatically revised to set a point to D, a process that requires the user does not know.
The use of other local search tools users will know that in the search before the need to spend a few hours of time to establish relations between the index. Vista system is also based on this principle, however, because the index system compatibility and integration is very good, so the indexing process does not give people a serious slow down the speed of the system is running the feeling.
Technical Comments: To be blunt, Lightning is in the index directory search on the basis of, Vista will be set up in peacetime on the disk all the files and directories index relations and maintaining an index table, when you're looking for information directly from the index for Can be. This index can be compared to our books in the catalog, can be directly under their turn to find the contents of the corresponding page .
Create a multi-directional high-speed search engine
Of course, in addition to using the services index main factors to increase the speed of search, Microsoft has introduced in Vista, such as virtual folders, the combination of enquiries, save search results, classification search, speaking of the search, and other concepts, through these means can also increase Search for speed.
1. Virtual folders
Virtual folders (Principle shown in Figure 2) the concept of Vista search is the first time in the introduction, it can help us in different directory with the same characteristics of the document extracted from the establishment of a virtual not real folder to facilitate We find and browse.
A virtual folder will be established in Windows Explorer and Windows Media Player, and so can view the document on your hard drive in the process. From a technical point of view of virtual folder is actually a search index changes and extension, it will index virtual directory, allows users to be in the form of virtual folders to see the existence of these index directory. In actual use of it can help users regularly visit the quick information needs of their own.
2. Portfolio for
Portfolio enquiries (Query Composition) technology is also the first time in Vista become clear. The so-called portfolio is in response to a query Search results on the basis, through the search for further conditions to achieve the limit. In this way, greatly narrowing the scope of the search, efficiency and speed to a large extent by the guarantee. Straightforward to say that this approach similar to the common "in the results View," which helps users step by step to gradually find their own camps the information they need. The ultimate combination for helping us to achieve a coarse to fine, from fuzzy to the precise course of the enquiry.
3. Preservation of search results
Many users of the system you will always find the same type of content, search in Vista also introduced the results of the preservation of function, we can save the search results of the search for a special folder, the folder and ordinary compared to the search results document Folder set up to hide the default format, but its content is dynamic, which is contained in the files and folders with the file system will change automatically added or deleted, in real-time search of the match. Save this search technology is that the essence of the results are not kept by the same, but with the operating system files and change the path of real-time changes, this will quickly show a more accurate search results.
4. Categories Search
In order to speed up the pace of search, Microsoft's search uses a concept called the search request. The so-called Category search means in accordance with current users of the search operation, such as when the user opens the control panel after the search through the search function, it will only control panel icons and options related to the content to find another when the user opens Windows Media Player player to listen to the songs using the search words, the system will only. Mp3,. Wav format, such as audio files to find. To be blunt, what procedures you use the search function, it will be able to open proceedings against any of the documents or procedures in which the option to find. In addition there is a search request such benefits, that is, software manufacturers can easily use a search function, the search module added to the third-party software.
Technical Comments: This classification search, the search function is actually divided into a number of small search function, in different tools for different content to search the one hand, the user can view the operation of preferences to traverse and find the other because Reduce the number of search content, thereby greatly increasing the speed of search.
5. Parade of the search can be
Vista system in the search operation is extremely cordial, and we can almost be in any corner of the search found the shadow. No matter the start menu or the control panel, whether from the Explorer or the IE 7 browser, even from the Windows Photo Gallery and Windows Media Player, can be directly call search function. This search system throughout the layout, allowing the user to find information in the search immediately when, in effect increase the speed, also allows users to more easily get started, do not have frequent calls to return to the desktop search the menu.
Fully learn from the Web search technology
In fact the local search and Internet search query information on a similar principle, the search engine on the main principle at work is divided into a purely technical type of full-text retrieval search and directory search, the former through the process to the various places to collect information, the index database , In the search results on the speed of it is to win, but the result is not real-time information, are in the earlier period of time to the collection. Category search while the latter is through the keywords of the corresponding audit information and artificial set up, this search is the true victory, and its results are very accurate.
From a principle perspective, Vista local search is more like a combination of both, on the one hand through the search process to the hard drive in various sectors and various disk directory to search, index database; On the other hand through the contents of the documents in the establishment of Keywords Traversing a database. Two databases to work together to allow us to quickly and accurately find the content.
Forecast: Vista search for the future
As the corresponding server version of Vista, Windows longhorn will continue Vista search function is an indisputable fact. In addition to Vista search of the future, Editor's Note that the rate of increase not very meaningful, there will be no revolutionary changes. Therefore, we can boldly predict its future: As Microsoft's acquisition of more and more well-known software firms, search supported by the file format will be more and more in the search and content will not be limited to the current content and related documents Information, previously modified the content and information will also be able to find through search function, which can then be careful not to delete the contents of the documents adopted after the search function will be their "back" .
