Nobody wants to be trapped in such a situation... but sometimes luck betrays us: Windows Update says there's a new update for us, and no matter how many times we try, that update fails with a mutating error code that only Redmond understands. Below we'll share some strategies to repair Windows Update in Windows 10, and additional resources in case you want to take the risk and perform major surgery…
Windows Update: Necessary Evil
Windows Update behaves like a volatile god. When everything goes well, it stays in the background solving problems and optimizing our environment... but if something goes wrong, its destructive potential is absolute. The worst part is that problems aren't limited to the update delivery mechanism: many times, the ones responsible for breaking the operating system are the very hotfixes that Redmond publishes.
If you've come to this article, it's because you need to know how to repair Windows Update in Windows 10. Getting Windows Update back from the darkness is a frustrating and uncomfortable mission, but not impossible. Today we'll share the most common recovery techniques, and links to documentation that will let you intervene in Windows Update more deeply.
Learn to repair Windows Update in Windows 10
Start with the essentials
What does that mean? Three things: Check the available space on the system drive, verify that your internet connection works and is stable, and restart your computer before attacking Windows Update directly. The supposed failure in updates might not be an error, but a simple delay.
A chance for the troubleshooter
The historical reputation of the built-in Windows troubleshooters isn't great, but in the specific case of Windows Update on Windows 10, it's definitely worth a try. Go to Settings -> Update & Security, then Troubleshoot, and finally Additional troubleshooters. Windows 10 will start a wizard, followed by the execution of several automatic processes. If Windows detects and fixes something, it's a good idea to restart your computer.
Manual installation of updates
Maybe the problem isn't Windows Update in general, but the installation of a specific hotfix. I've personally noticed that Defender definitions are very temperamental and often get stuck halfway. One way to unblock those finicky updates is to download their standalone copies and start a manual installation so Windows Update will let them go.
Patches for Windows 10 (and previous editions) can be found on the Windows Update Catalog. Use the KB code to find the hotfix, but you'll also need to confirm your operating system version and architecture. Meanwhile, Microsoft Defender definitions can be downloaded through this link. Again, remember to check your Windows version and architecture.
(Editor's note: Manual patches with the .msu extension should install with a double click. If that doesn't happen, open a console with administrator privileges and use the command "wusa nombredelhotfix.msu" to start its installation.)
Check system integrity
It's possible that the Windows Update failure is related to a corruption of operating system files. If you suspect that, you need to open a console with elevated administrator privileges and run the following command:
dism /Online /Cleanup-image /RestorehealthOnce that process finishes, you should continue with the classic System File Checker and its Scannow parameter:
sfc /scannowRestart your computer and try Windows Update again.
What if none of this works?
If the commands we've shared here don't get Windows Update to react positively, the damage is probably more extensive than expected. Your last option (and I emphasize "last") is to attempt a restoration from the command prompt. The guide published by PureInfoTech has everything you need, but it generally boils down to five steps:
- Stop all services related to Windows Update
- Delete all its download folders, including SoftwareDistribution
- Restore security descriptors in the main Windows Update processes
- Manually register more than two dozen libraries in Windows
- Reset network parameters
I insist: this is equivalent to a complete rebuild, but it offers no guarantee, and it's an option that should only be explored if everything else fails. In fact, I'd dare say that if Windows Update is that damaged, the most practical and effective thing is a full reinstall of the operating system. I hope you don't have to go to that extreme, and that some of the above points help you repair Windows Update in Windows 10. Good luck!
