Yes

Refer to this to clean up the C drive:
1. Disable System Restoration: My computer properties/System Restoration/disable System Restoration on all disks, but I will not be able to use system restoration in the future!
2. Disable System sleep: Control Panel/Power Supply/sleep/remove the check before starting system sleep
3. move the virtual memory, my computer properties/advanced/performance/settings/advanced/change/select the C disk, that is, the system disk, select the no-score page, and then set the virtual memory to its disk, A disk with more disk space remaining, such as D, E, and F. set to 1.5 ~ of memory ~ 2.5 times. The size can be set to the same!
5. Clear temporary IE folders, internet Options, and delete temporary and offline files.
6. delete system logs and program logs, my computer/control panel/management tools/Computer Management/Event Viewer/application, right-click/clear events, and clear system logs in sequence
7. Clear system cache: 2000 all files in the system: C: \ WINNT \ system32 \ dllcache
The XP system is: C: \ windows \ system32 \ dllcache all files under the system cache (open my computer/tool/file and Folder Options/hide the protected system file hook off to hide all files on the hook) ). You can also run the sfc.exe/purgecache command to automatically delete the file.
8. Clear the recycle bin
9. delete the files under c: \ windows \ SoftwareDistribution \ Download (the files downloaded when the system is updated are useless if you have installed the updates)
10. Delete all directories under c: \ windows \ RegisteredPackages
11. Delete all Files under C: \ WINDOWS \ Downloaded Program Files
12. view the hidden files that are known to be protected by the system in my computer folder option, and check all the files.
13. Delete c: \ windows \ All files with $8882305 $ (backup files after system update)
