How to clean disk in Win7
As the computer usage time increases, the system disk (usually the C drive) will accumulate a large number of temporary files, caches and useless data, resulting in insufficient disk space and affecting the running speed. For users who are still using Windows 7 systems, regularly cleaning the disk is the key to keeping the system smooth. This article will introduce in detail the various methods of cleaning disk in Win7 and provide structured data for reference.
1. Use the disk cleaning tool that comes with the system
Win7 has a built-in disk cleaning tool, which is simple and safe to operate:
| steps | Operating Instructions |

| 1 | Click "Start" → "All Programs" → "Accessories" → "System Tools" → "Disk Cleanup" |
| 2 | Select the disk that needs to be cleaned (usually the C drive) |
| 3 | Check the file types you want to delete (such as temporary files, recycle bin contents, etc.) |
| 4 | Click "OK" to perform cleanup |
2. Manually clean up common junk files
The contents in the following folders can be cleaned manually (it is recommended to back up important data before operation):
| folder path | Cleanable content |

| C:Users[username]AppDataLocalTemp | User temporary files |
| C:WindowsSoftwareDistributionDownload | System update cache |
3. Clean up system restore points and shadow copies
System restore points take up a lot of space and can be cleaned by following these steps:

| 2 | Select the disk → click "Configure" |
| 3 | Click "Delete" to clear all restore points |
4. Uninstall rarely used programs
Uninstalling programs through Control Panel can free up a lot of space:
| steps | Operating Instructions |
|---|---|
| 1 | Open "Control Panel" → "Programs and Features" |
| 2 | Sort by size and uninstall software that has not been used for a long time |
| 3 | Pay attention to retaining the necessary components of the system |
5. Use third-party cleaning tools (choose carefully)
