Hi,

I wonder if there is any possibility that we can delete Windows updated files which begins with KB and recover disk space? Or we must not touch that?

If it is possible what would be the procedure on Windows Vista 32 bit machine?

Any advice in this regard will be appreciated.

Thank you

You may have read that Windows 7 SP1 recently started allowing an Update Cleanup option in the Extended Disk Cleanup tool. Vista doesn't have this, yet anyway.

It's not quite the same having Windows decide what's cleanable and doing that yourself. I wouldn't try doing it yourself.

You never delete anything that is installed, you uninstall it, but never updates as they are cumulative. All Windows Updates begin with KB and should not be uninstalled. unless you wish to have them re-offered by Windows Update which is useful if one becomes corrupted for instance.
You can clear up a lot of stuff by using Disk Cleanup: http://www.vistax64.com/tutorials/76073-disk-cleanup.html or Extended Disk Cleanup: http://www.vistax64.com/tutorials/158356-extended-disk-cleanup.html


Hi, Thank you for good reply.
Actually I got an e-mail and I was reading how to recover disk space by deleting windows update in Windows 7.
Therefore, I asked this question for Windows Vista and you saved me. Regarding the link for extended disk cleanup I wonder if the shortcut utility will work on Japanese windows and what should be checked and un checked?
Though I have downloaded the shortcut utility I will check if it work or not but won't use unless I get reply from you.

Thank you.

Just use your best judgement on that as I'm afraid I'm not a Japanese speaker. If you Google or other search for how to do an extended disk cleanup in Vista in your own language it may help.

Hi, thank you for your answers.
I extracted the downloaded short cut utility and made a short cut on desktop from their I clicked on it and it ran in JAPANESE. It worked and showed more options to be checked which I did not because I am not sure which to check or not.

Thank you.

I would research it if I were you. There are numerous entries on Microsoft's own forums about the pros and cons of doing that. Basically you will be wiping out Windows Update history.
I wouldn't do it but then in my case the folder isn't that big plus my drive has lots of room.

The biggest gain would be from deleting shadow copies and old restore points

You can delete those without any issues. After the updates have been installed, you don't need them. Has no effect on update history, or the ability to uninstall updates. You may save a few hundred mb.

Good point by ilikefree. From memory Vista allocates 15% to shadow copies. I recommend keeping shadow copies ( sometimes called restore points ), you may find reducing it to 5% will be enough for a few shadows and still release quite a bit of space.

Regarding shadow copies I will check that. Good idea.
