Windows Update Problems: What to Do When Updates Won't Install
Windows update stuck, failing or showing an error code? Here are ten practical checks you can make before getting professional help with a Windows Update problem.

Windows updates are designed to keep your laptop secure, stable and up to date. Most of the time they download and install in the background without you having to think about them.
But sometimes Windows Update simply refuses to cooperate. An update might get stuck at a certain percentage, repeatedly fail to install, display an error message, or appear to download successfully before asking you to try again.
If you have been dealing with Windows Update problems, there are several things you can try before looking for more advanced help.
Why won't my Windows update install?
There isn't one single reason why a Windows update might fail. The problem could be something relatively simple, such as not having enough storage space or an unreliable internet connection. In other cases an existing Windows fault, damaged system files or a software conflict could be preventing the update from installing correctly.
Common causes include:
- Not enough available storage
- An unreliable Wi-Fi connection
- Another update waiting to be installed
- A temporary Windows Update error
- Corrupted system files
- Software conflicts
- Problems with Windows Update services
- Outdated drivers
- A problem with the particular update being installed
The good news is that many Windows Update problems can be resolved without replacing your laptop or carrying out a major repair.
1. Check your internet connection
It sounds obvious, but a poor or unstable connection can stop an update downloading properly. Check that other devices can reach the internet normally, and avoid large downloads or streaming while the update is running.
2. Restart your laptop
If an update appears to be stuck, a restart can clear temporary processes and let Windows start again. If Windows is already showing that an update is ready to restart your laptop, allow it to finish rather than repeatedly shutting the device down.
3. Check how much storage space you have
Updates need free space to download, unpack and install. If your laptop is low on storage, an update may fail even though everything else looks fine. Our guide on how to free up space on your PC walks through what is safe to remove — back up personal documents and photographs before you delete anything.
4. Check Windows Update again
After checking your connection, restarting and freeing up storage, try again. If it fails, note the exact error message or error code that appears.
5. Run the Windows Update troubleshooter
Windows includes troubleshooting tools designed to spot common problems. The exact location varies by version, so look for the troubleshooting options in your Windows settings. It won't fix everything, but it is a sensible step before more advanced work.
6. Check whether another update is causing the problem
Sometimes an update won't install because another update or system process needs to finish first. Restart if Windows asks you to, and let the process complete. If several updates fail repeatedly, the problem is likely more than a pending restart.
7. Look at the Windows Update error code
Error codes look confusing, but they help identify the underlying problem. Write down the exact code rather than searching for a general phrase. Use Microsoft's official guidance where possible, and be cautious of websites that claim to fix update errors automatically — some use fake warnings to push unnecessary software.
8. Check whether other software is interfering
Security software and other applications can occasionally interfere with updates. Close programmes you don't need and try again. Don't disable security features or uninstall important software just because a forum suggests it. If the problem began after installing new software or a driver, consider whether that is connected — and see our guide on how to tell if your laptop has a virus if you suspect something unwanted is installed.
9. Try restarting the Windows Update process
Windows uses several background services to download and install updates. If one becomes stuck, updates may repeatedly fail. Resetting these components is more advanced work, and running commands you don't fully understand can cause further problems. If you have reached this stage and aren't comfortable, professional support is the safer option.
10. Check whether Windows has other problems
If updates have been failing for a long time, there may be a wider issue. Damaged system files can interfere with updates, and you may also notice:
- Programmes crashing
- Your laptop freezing
- Unexpected error messages
- Slow startup
- Problems opening certain applications
- Frequent restarts
- Other Windows features not working properly
If several of these appear together, repeatedly retrying the same update won't address the cause. See why is my laptop running slow for related software causes.
What if Windows Update is stuck on a percentage?
Give it time first — large updates can take longer than expected on older or slower laptops. If the laptop has genuinely been unresponsive for a long period you may need to restart it, but repeatedly interrupting an update while files are being written isn't advisable.
Should you ignore a Windows update that won't install?
No. Updates contain security fixes as well as improvements, so keeping Windows current matters. That doesn't mean forcing the same update over and over — if it keeps failing, investigate the underlying problem.
When should you get professional help?
Professional computer support can help if:
- Windows updates repeatedly fail
- You keep receiving the same error code
- Windows Update is permanently stuck
- Your laptop has other software problems
- Windows is crashing or freezing
- You are uncomfortable using advanced troubleshooting tools
- You have tried several fixes without success
A technician can look at the wider system rather than treating the failed update as an isolated problem.
Can a Windows Update problem be fixed without replacing the laptop?
In many cases, yes. A failed update does not mean your laptop is too old. If the device is otherwise working properly, the problem usually just needs diagnosing. Our article on whether it is worth getting a laptop repaired covers how to weigh up repair against replacement.

Frequently asked questions
Why does my Windows update keep failing?
Common causes are low storage, an unstable internet connection, a pending restart, corrupted system files, software conflicts or a problem with Windows Update services. The error code shown usually points to the cause.
How long should I wait if a Windows update is stuck?
Large updates can take an hour or more on older laptops. Wait until the laptop has been genuinely unresponsive for an extended period before restarting, as interrupting an install can cause further problems.
Is it safe to skip a Windows update?
Delaying briefly is usually fine, but ignoring updates indefinitely leaves security fixes uninstalled. If the same update keeps failing, fix the underlying issue rather than skipping it.
Can Windows Update problems be repaired remotely?
Many software-side update faults can be diagnosed and resolved without any hardware work, which is why a software-focused repair service can often sort them quickly.
