My Dell laptop is the original w7 system, and the C drive accounts for almost 50g. It runs very slowly, and there are often hints of insufficient memory.

It's actually quite simple. . It's just that there are too many things in disk C. I recommend a few tricks for you:

1. In the function encyclopedia of 360 security guards, there is a C disk to move. You can move things. Lighten the burden on disk C, but remember that the file system moved to disk must be NTFS (the file system can be seen in the properties of disk). Otherwise, if none of them are NTFS, please click/question/question/1968758.html.

2. Download Jinshan Reinstall. It works well. Reinstall the system.

3. Turn off some startup items that can be started without booting.

4. At 360, the software manager uninstalls the software. There is a frequency of using software. You can see which one is used less. Unload him. .

5. When installing the software, you can install it on another disk. You don't have to use disk C.

The above is my personal opinion. I hope the landlord will adopt it
