Disk Cleanup can free up C disk space by cleaning up the system, updating residual, temporary files and recycling bin content, system restore points, and using the "Clean System Files" function. The specific steps are: 1. Check "Windows Update Cleanup" to delete the old update files, but it cannot be rolled back; 2. Check "Temporary Files" and "Recycle Bin" and other basic projects to clean up; 3. Carefully check "System Restore and Shadow Copy" to delete the old restore point; 4. Click "Clean System Files" to expand to scan more system-level garbage. Reasonable operation can free up several GB of space, which is suitable for confirming that the system is stable.

Disk Cleanup, a disk cleaning tool that comes with Windows, is actually a very practical gadget. It can help you free up space in the C disk, especially after the system is running for a period of time, the junk files such as temporary files and updates still take up a lot of space. If used well, you can free up a few GB of space in just a few strokes.

Clean up system update residues

After the Windows system update is completed, the old version of the update file will be retained in case you need to roll back. But if you are sure that the system is fine, this part of the file can be cleaned.

After opening Disk Cleanup, find the "Windows Update Cleanup" item in the "Files to be deleted" list, check it, and then click "OK". However, be aware: after cleaning, the latest updates can no longer be uninstalled.

Operation suggestions:

• Suitable for execution after confirming that the update is running stably
• It will not affect the current system function
• Usually it can free up hundreds of MB to several GB of space

Delete temporary files and recycle bin content

This is the most basic and common way to clean up. During the run, Windows will generate a large number of temporary files, such as browser cache, installation package, system log, etc. Most of these files are useless.

In the Disk Cleanup interface, check the options "Temporary Files" and "Recycle Bin" and click "OK" to clean it up quickly. Sometimes you can also see the option to "Download" folder, which can also be processed together.

Common Situations:

• The browser has not cleared the cache for a long time, which may take up several GB.
• It is particularly worth clearing when there are large files in the recycling bin
• Too many temporary files may affect system performance (although rare)

Clean up the system restore point (operate with caution)

The system restore point is a function used by Windows to restore the system state, but it will also take up a lot of space. If you want to save space, consider deleting old restore points.

However, be careful when you delete it: once you delete it, you cannot return to the previous system state through the restore point. If the system is currently running normally and you do not need the fallback function, you can check "System Restore and Shadow Copy" to clean it up.

remind:

• It is not recommended to operate when the system is adjusted just now
• You can first see how much space this option occupies before deciding
• If the hard disk space is sufficient, it is not recommended to delete it

Extend functionality with Clean System Files

Many people don’t know that Disk Cleanup only displays a part of the content that can be cleaned by default. After clicking the "Clean System Files" button, it will rescan and display more system-level garbage, such as the aforementioned update residues, restore points, etc.

Operation process:

1. Open Disk Cleanup
2. Click "Clean System Files"
3. Select the items you need to clean up
4. Confirm deletion

This can release space more thoroughly, especially when the C drive is almost full, which is worth a try.

Basically these common functions. Disk Cleanup looks simple, but it is quite effective when used correctly, especially for friends who don’t want to install third-party software. The key is to distinguish which ones can be deleted and which ones must be kept, and don’t try to save trouble and eliminate important data.
