[Win7 installation] slimming and cleaning work after installing Windows7
The first step is to open an administrator account and get the highest management authority first. The method is as follows:
Right-click Desktop Computer-Administration, Local Users and Groups-Users, right-click Administrator-Properties, remove the check mark before "Account Disabled", and log off the current user to the administrator account.
1. Disable hibernation, click Start menu, all programs → accessories → command prompt, right-click "Run as administrator", enter "powercfg -h off" manually after entering the command prompt and press enter; You can delete hibernation files through disk cleaning in Vista.
2. Delete system backup and turn off system protection: right-click desktop computer-properties-advanced management settings-system protection, select the disk with system protection turned on, configure it, select "Turn off system protection", and then apply and confirm.
3. Transfer virtual memory: right-click the desktop computer-Properties-Advanced System Settings-Advanced-Performance-Settings-Advanced, click the "Change" button under "Virtual Memory", cancel the "Automatically manage the paging file size of all drives" check box, select the system disk where the virtual memory is located (usually on drive C), and select "No paging file" below. Select another disk and put the paging file on it. If the memory is larger than 4GB, you can consider not setting virtual memory.
4. Transfer users' files (double-click the administrator folder on the desktop). It is suggested to transfer the following system folders:
Favorites, videos, music, pictures, documents. Right-click the project property to transfer-location X:\Users\Administrator).
Generally, the above four steps are enough. The following steps start deleting files, which can be ignored if there is enough hard disk space.
Manual slimming strategy (deleting files without deleting functions simplifies and optimizes system performance)
1.c: \ Windows \ Web \ Wall * * * (Windows wallpaper) recommended for transfer.
2. Under C: \ Windows \ System32 \ DriverStore \ File Repository:
Search and enter ATI *. INF (14.6m) NV *INF (94.9m) (A NVIDIA will be deleted for A card users and ATI will be deleted for N card users).
Search input mdm*. inf (2 1.6M)
Search input prn*. Inf (78 1M) prn starts all printer drivers, which I believe most people don't need.
Note: prnms001.inf/prnoc001.inf/prnms002.inf is not a printer driver, so it is recommended to keep it.
3.C:\Boot (13.3M), a Windows startup interface in different languages, can be deleted except zh-CN.
4. c: \ perflogs \ system \ diagnostics (9.39m) This is the storage location of the test record file after the system test, so it is deleted.
5. C: \ Windows \ downloaded program files Some programs will extract the installation files into this folder when installing. Can be safely deleted, ranging from tens of meters to hundreds of meters.
6.C:\Windows\Help (66.7M) can be deleted.
7.C:\Windows\IME\IMESC5 (those using third-party input methods can be deleted).
Microsoft pinyin input method (74.5M) can be left.
C:\Windows\IME\IMEJP 10
Japanese input method (37.8M) has been deleted.
C:\Windows\IME\imekr8
Hangul input method (2.86m) has been deleted.
C:\Windows\IME\IMETC 10
Traditional Chinese input method (2 1.6M) was deleted.
These input methods will also be available under C:\Windows\System32\IME, and the deletion method is the same as above.
" C:\Windows\System32\IME\IMESC5 "
" C:\Windows\System32\IME\***X "
8.C:\Windows\Installer, the installed program needs to be uninstalled and modified. If deleted, some programs will be uninstalled and modified.
9.C:\Windows\winsxs cannot be deleted, but it can be compressed. After compression, the size is 2.48G, which saves nearly 1G space, and the total size of system files is 3.22G (Personally, I suggest not to move this).
C:\Windows\winsxs\Backup (backup file, occupying 354MB), which can be deleted.
10.C:\ProgramData Some programs will put some files in it when they are installed, depending on whether they need to be deleted. The installation files exe and msi can be deleted, but some of them are needed when the software is running, and cannot be deleted casually.
11.c: \ program files \ The Microsoft game system comes with games, and games that you don't play can be deleted. The method of deleting the game is as follows:
Start-Control Panel-Programs-Turn Windows features on or off. Find the game, click the plus sign to expand, remove the check mark in front of the game to be deleted, and then confirm. At the same time, the functions that can be turned off include tablet optional components /Windows DFS service/printing service /Windows fax and scanning /Windows meeting room/remote differential compression. If you need to open IIS, you can open the Internet information service here.
The following are not deleted casually:
C:\ Program Files \ Microsoft Games \ Chess
Chess master (30.3m)
c:\ Program Files \ Microsoft Games \ FreeCell
Free battery (690,000)
C:\ Program Files \ Microsoft Games \ Hearts.
Battle of hearts (687K)

C:\ Program Files \ Microsoft Games \ Minesweeping
Demining (4.96m)
C:\ program file \ Microsoft game \Purble Place
Kitchen Competition (3M)
C:\ Program Files \ Microsoft Games \ Cards

C:\ Program Files \ Microsoft Games \ Spider Solitaire

12.C:\Users\Public (it can be deleted)
All users' public folders contain some sample pictures and videos, which can be deleted (2 17M), where c: \ users \ public \ recorded TV \ sample media is a sample TV recording file of Windows Media Center (143M) and c: \ users \ public \ music \ sample music is sample music.
Modify the registry to speed up the startup of Windows 7 system.
1) Run regedit to enter the registry.
2) Open to: HKEY _ local _ machine \ system \ current control set \ control \ session manager \ memory management \ prefetch parameters.
3) In the "EnablePrefetcher" primary key on the right, change its default value from 3 to 0.
4) Restart the computer
Modify the registry to speed up the shutdown of Windows 7 system.
1) Run regedit to enter the registry.
2) HKEY _ Current _ User Control \ Panel Desktop, just set the key value of "AutoEndTasks" to 1.
3) Then change "HungAppTimeout" to "4000 (or below)" (default is 5000), and the key value is also under "HKEY _ Current _ User Control Panel Desktop"; The last step is to find "HKEY _ Local _ Machine System Current Control Settings Control", and also set WaitToKillServiceTimeout to "4000";
Remove menu delay
Removing the delay when the menu pops up can speed up the speed of Window7 to some extent. The key value to be modified is in HKEY _ Current _ User Control Panel Desktop. Modify the "MenuShowDelay" key under it, change the default 400 to 0, press F5 to refresh the registry, and restart it to take effect.
Reduce the waiting time before closing applications and processes.
Similar to the waiting time before shutting down the service, Windows Vista also has a period of time to wait for the program or process to shut down on its own, and then forcibly shut down the application or process. Only after this time limit is exceeded will the Windows system stop forcibly. Therefore, shortening the default application shutdown or waiting time can also speed up the shutdown of Windows 7.
The setting method is similar to the above. Find the following branch in the registry: HKEY _ Current _ User \ Control Panel \ Desktop, and double-click "WaitToKillAppTimeout" in the right panel to change its value from the default 20000 (also in milliseconds) to a smaller 5000 or 1000. In this way, if Windows waits for 5 seconds or 1 second after issuing the shutdown instruction, a corresponding warning signal will pop up and ask the user whether to stop forcibly.
