where does 'Windows Update' saves its downloads?
For example, I've used windows update service to selected a patch about 'computer fails when connected to a UPS
'. It was downloaded and installed successfully. But I failed to find the downloaded file in my local machine. I need to save copies of such patches for later use, in case of a disk format or fresh windows install.
In that particular example, I have managed to get the name of the file: Q310437_x86.exe, which is a 161k file
so I seached my disk, only to find that the only file similarly named is called: Q310437_X86.EXE-036F9854.pf , a 12k file, and it was saved in folder: C:\WINDOWS\Prefetch
So what does that mean?
does windows delete downloaded update patches after installing them? are these .pf files just a history file telling windows what updates exist in a machine's system?
If so, can that behavior be prevented, so that download patches stay and dont get deleted automatically?
