In the past few days, Microsoft has issued a Cumulative update to make improvements to the functionality of Windows 10. This update (KB3081424) was, ironically, meant to fix many of the bugs users have experienced since upgrading. However, for some users, attempting to install this update has caused further issues.

For affected users, the update process reaches a certain percentage before getting stuck. They then receive the error message “We couldn’t complete the updates, undoing the changes,” resulting in a mandatory system reboot while the update is uninstalled. Now, I know what you’re thinking – “this isn’t too big a deal, I just won’t uninstall the update” – unfortunately, at some point after a user logs back in, the Window’s 10 update process kicks in and attempts to install KB3081424 again, resulting in an endless loop of trying, and failing, to install the update.

The reason for KB3081424 failing to install correctly is apparently linked to bad entries being made in the Windows 10 registry. Microsoft has announced that it is working on a patch for this, but in the meantime, some users have discovered a fix that removes the bad registry entry and allows update KB3081424 to install correctly.

If you have been affected by this update issue, here is a guide on how to fix it…

How to fix failed update installation

Step 1: Go to the start menu, or press Windows Key + R, and enter “regedit.” Press Enter to run the command.


Step 2: In the window that opens navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList


Step 3: The next step is risky so backup your registry key! To do this, select “ProfileList,” right-click on it, choose “Export” and then type in a filename of your choice and save it to the desktop.


Step 4: On the left, you should see a list of profile IDs (such as “S-1-5-18”). Clicking on these ProfileList IDs will show a list of registry entries on the right side. If any of these entries have the name “ProfileImagePath,” right-click on it and delete it. Do this for all ProfileList IDs.


Step 5: Close the regedit file and reboot your system. Once fully booted up, click Start > Settings > Update & Security – you should now be able to see KB3081424 and the next time it installs, it should do it without issue.

Hopefully, this fix will help you overcome any installation errors you are having with update KB3081424. If it worked for you, please let me know in the comments and like and share this post to let other people know about this fix! 🙂
