Win7 method for finding and deleting system update files

Every time the Win7 system is automatically updated, it will download a bunch of update files, all of which are patches. After installation, these files still occupy the system memory. If you want to delete, you don't know where the location is, so you must know first. Win7 system update files can be deleted. The following describes how to find and delete update files.

a, Win7 file system update automatically updated location

Win7 system is relatively complex, because the patch is compressed, it has three paths, a path memory is compressed, the first The second is the compressed package decompression path, the third is the installation path, the path is:

C:\\Windows\\SoftwareDistribution\\Download\\Install "Compressed package storage path"

C :\\Windows\\System32\\catroot\\{F750E6C3-38EE-11D1-85E5-00C04FC295EE} "Compressed package decompression path"

C:\\Windows\\servicing\\Packages "Installation path"

Second, 360 security guards "Repair Vulnerabilities"

This is relatively simple, the default path is C:\\Program Files\\360\\360safe\\hotfix, it has two settings, one is to clean regularly One is not to clean up, it depends on how you set it up.

The above is the way Win7 finds and deletes the update file. You can use the tool to clean it up, or you can find the storage location to delete it manually.
