In fact, the method of slimming drive C of Win7 system is very simple. There are the following technical solutions, which I hope will be helpful to the subject:

1. Open the administrator account, and then go to Control Panel-Programs-Turn Windows features on or off-and then close Windows Media Centre and Windows Media Player. If the topic owner needs to turn off other functions, he can also choose by himself, without turning off WMC and WMP. I just found that closing WMC and WMP can save a lot of space, so I suggest closing them.

2. Install 360 security guards, enter the C drive-Program Files folder, find a folder named Windows Defender, right-click this folder, then click "360 Power Delete" and crush it with a 360 file shredder. In fact, Kingsoft Internet Security/Computer Butler/tinder security can also be crushed. Just turn on the file shredder function.

3. Regularly use software to clean up the garbage of Windows system, and browse the cached files and the garbage generated by the software of disk C on the Internet. The space occupation of that C disk can be reduce.

4. Don't install the software on disk C, install the software on disk E or other disks.

5. uninstall Microsoft Office and replace it with WPS20 16.

Hope to adopt. Thank you. I hope my answer can be helpful to the subject.

I wish you a smooth use!
