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…
