Delete $PatchCache$ directory in Windows Installer directory?

Recommended Posts

PatchCache has been around since XP and I believe it's used to store certain updates you get through Windows Updates.

So although it can be deleted with seemingly no immediate effects, I think in the long term you may get Windows and other Microsoft problems (like with Office) when it comes to uninstalling/updating.


a lot like those $NtUninstallKB files.


in short, you could, but unless you really have to, leave them alone.

Backup now & backup often.
It's your digital life - protect it with a backup.
Three things are certain; Birth, Death and loss of data. You control the last.
