Windows 7: Can files located in C:\Windows\Installer be deleted? [duplicate]

The folder (C:\Windows\Installer) on my Windows 7 installation holds 1GB of installers are these necessary or can these be deleted ? If so are there any other places where Windows 7 saves the installers which are used to install files and can they be removed ?


Solution 1:

Don't delete this folder or its content.

Use the Windows Installer CleanUp Utility instead as it will properly unregister files.

Solution 2:

You can safely compress C:\Windows\Installer if you want to.
