There are many ways to lose weight online. Give it a try:

Slimming and cleaning of windows 7

The first step is to open an administrator account and get the highest management authority first. The method is as follows:

Right-click Computer-Administration, Local Users and Groups-Users, right-click the Administrator attribute, remove the check mark before Account Disabled, and log off the current user's login 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 the backup and turn off system protection (right-click Computer Properties-Advanced Management Settings-System Protection).

3. Transfer the virtual memory (right-click Computer Properties-Advanced Management Settings-Advanced-Performance-Settings-Advanced-Change).

4. Transfer user files (double-click the administrator folder on the desktop and suggest transferring the following system folders:

Favorites, videos, music, pictures, documents. Right-click the project property to transfer-location X:\Users\Administrator).

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 Installations Some programs will extract the installation files into this folder during installation. 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

C:\Windows\IME\imekr8

Hangul input method (2.86m) has been deleted.

C:\Windows\IME\IMETC 10

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.
