How to remove and reinstall all Windows Updates

Posted on September 10, 2008 at 5:25 am

Have you ever come across a situation where Windows Update gives you the message “An update failed to install” and gives you no other option? This can happen for a host of reasons and the first thing you want to do is search that phrase along with the update that failed to install.

There are some occasions, however, where you have to start from scratch and reinstall all Windows Updates from the beginning. Other than reformatting your computer and then installing every update again, you can also delete the folder that contains the updates and update history.

Once you delete the automatic updates folder, the next time you check for updates or go to the Windows Update website, all updates will be re-downloaded and re-installed.

How to reinstall all Windows Updates

First, you have to turn off the Automatic Updates and BITS service in Windows. To do this, click on Start, then Run and type in services.msc and press OK.

Next, right-click on Automatic Updates service and click on Stop. Right-click on Background Intelligent Transfer Service and click on Stop.

Now we can delete the folder that contains all of the Windows updates applied to your computer currently by navigating to:

C:\Windows\SoftwareDistribution

Note that this will delete the Update history and ALL updates will be reinstalled on your computer. Note that this will not harm your computer in any way.

Now you can go ahead and restart the two services that we stopped earlier. If you are running Windows Vista, type in Windows Update in the search box and press Enter.

Windows Updates should show you that you’ve never checked for updates before, so go ahead and click “Check for Updates” to begin re-installing all updates.

In Windows XP, make sure Automatic Updates is set to “Automatic (recommended)” via the Control Panel and then visit the Windows Update website to begin installation of the updates.

Hopefully, once the initial updates are reinstalled, your failed updates will install also. Enjoy!

    My Mother-in-law pulled out a program disc halfway through installation, which jammed up windows installer. I fixed that by finishing the installation (putting the disc back in), but during the time she had the problem, which was right when she got the computer, 97 or so Windows Updates downloaded to the computer, but couldn’t install.

    These files include everything from the service packs (which are supposed to install by themselves), to critical updates. The computer is very slow at startup, and wants to install the files at shutdown.

    I just want to find the file where the downloads are sitting, wipe them out, and start again. Any ideas?

    Wanted to give you a big thanks on this. I was having problems with Windows Update Agent on a Vista Basic machine. wuauserv.exe was using high cpu cycles of about 50%. After digging around for a couple of hours, I tried reinstalling the update agent, reinstalling .net framework, and a host of other things. Your solution worked – THANK YOU! Your site is getting bookmarked. :)

    Interesting and useful – thank you … but I think you can achieve same in XP by going to “Change or Remove Programs”, tick “show updates” – then delete them one by one ! This should be the same as deleting the contents of Windows\SofwareDistribution … but then also the updates are lsited in Windows\ folder directly by KB number – if these are not “deleted” I think/guess you could end up with the names doubling ?

    @Jeff, sometimes deleting the updates one by one does not help. Something has gone wrong with the folder, etc and you have to delete all the updates and start over. I had a problem like that where something got corrupted and this was the only method that worked.

    This did not solve my problem. I continued to have the update fail.

    What I realised in Windows 7 is whenever an update fails, all you need to do is click on Check for updates option and windows will automatically attempt to reinstall failed updates. In my case a couple of updates that failed were successful the next time Windows Update was run.
