Windows update failed and prompted "Windows could not complete the updates" are problems that many users will encounter. This problem usually occurs when system updates are interrupted, file corruption or driver conflicts, and it is not particularly complicated to solve, but requires step-by-step investigation.

1. Try to enter safe mode and try to update again

• Restart the computer, press and hold the power supply forcibly shut down three times, which will trigger the automatic repair interface.
• Then select "Troubleshooting → Advanced Options → Start Repair" or go directly to "Safe Mode".
• Open "Settings → Windows Update" in safe mode and click "Try Update Re-Try Update".

Note: Safe mode only loads the most basic services and drivers, which can effectively eliminate some conflict issues.

2. Use the system's own update and repair tool

Windows comes with some command line tools that can help fix update failures.

You can run the following commands in turn (open the command prompt as an administrator):

• sfc /scannow
  Scan and fix system file integrity issues.

• DISM /Online /Cleanup-Image /ScanHealth
  Check the system image for damage.

• DISM /Online /Cleanup-Image /RestoreHealth
  Automatically fix the discovered problems.

These commands may take several minutes to complete, and restart the computer and try to update after completion.

3. Delete the update cache and download it again

Sometimes the update file itself is corrupted and the installation failure can be caused. Clearing the old update cache is an effective way.

The operation steps are as follows:

• Press Win R to enter services.msc to find the Windows Update service.
• Right-click to stop the service.
• Enter the path: C:\Windows\SoftwareDistribution , delete all the files inside (or cut them to other places for backup).
• Return to the service list and restart the Windows Update service.
• Check for updates again and the system will download the latest update package again.

If you are not sure if you can delete it, you can cut it first instead of deleting it, and you can recover it if there is any problem.

4. Check driver compatibility or manually update drivers

Some old or incompatible drivers can cause update failures, especially key devices such as graphics cards, network cards, motherboard chipsets, etc.

you can:

• Use Device Manager to see if there are any yellow exclamation marks.
• Manually download the latest driver installation on the official website.
• Or use Microsoft's official driver rollback function (right-click on device → Properties → Driver → Rollback driver).

If you have just upgraded the hardware, such as changing the graphics card, remember to confirm whether the driver is compatible with the current system version.

If you encounter this type of update failure problem, you do not need to reinstall the system most of the time. As long as you follow the above steps to check, it can basically be solved. If it still doesn't work, you can also consider creating a new local account and try it. Sometimes the user profile will also affect the update process.
