Windows 7 Update Allows You to Delete Old Update Files

Windows 7 received a new update allows you to easily free up some disk space by getting rid of old update files. Here’s a look at how this new update works.

Windows 7 update, KB2852386, is now available for all Windows 7 users via Windows Update. If you have automatic updates enabled, you probably already have it installed. If you want to install the update , the x64 version can be downloaded here. The x86 one is available at this address.

Note: It’s worth mentioning that you’ll need to be run Windows 7 SP1 or higher in order for the update to work for you.

The update cleans up the WinSxS store, a place where Windows stores old update files. That’s done so you can later roll back to previous updates in case something doesn’t work as expected. Remember that, if you use this cleanup method, you may not be able to get back to an older update. However, in my experience, it’s rarely needed, if ever, and you can do it manually if it’s absolutely necessary.

Using the new feature couldn’t be easier. Open the Start menu and navigate to All Programs > Accessories > System Tools > Disk Cleanup. Alternately, you can type: disk cleanup in the search box as explained in this article.

    I tried to install the update, but it said it was already installed…then I ran Disk Cleanup, but the button was not there.

    I’m running Win7, SP1, 64 bit, and have had KBKB2852386 installed for 4 days with two reboots.
    However, the “Cleanup system files” option doesn’t appear. Do I need to remove the update and try again?

    Same here – the update is installed, but the “system files” option is not available.

      I take that back. What I did was run the clean-up tool anyway, and it rescanned the computer. This time, it DID list “system files”, and I was able to go ahead and clean it up.
