Windows update service not running
Jul 06, 2025 am 02:08 AM
The Windows Update service is not running can be resolved by checking the service status, using troubleshooting tools, rebuilding update components, and repairing system files. 1. Check whether the Windows Update service is disabled. If it is not started, set it to automatically and start manually; 2. Use the system's own troubleshooting tool to automatically scan and fix the problem; 3. Stop the relevant services through the administrator command prompt, rename the cache directory and restart the service to rebuild the update component; 4. Run the sfc and DISM commands to check and repair system file corruption to ensure that the service is running normally.
If the Windows Update service does not run, the system will not be able to automatically update patches, security repairs and other content, which will increase security risks in the long run. This problem is actually not particularly rare, especially on some old computers or machines that have manually adjusted the system settings.
Below are some common reasons and corresponding solutions. They are not complicated to operate, but they need to be done step by step.
1. Check whether the Windows Update service is disabled
In many cases, the problem is simply because the service is "shut down" or "disabled".
You can check it through the following steps:
- Press
Win Rto open the run window and enterservices.mscto enter. - Find the Windows Update item in the list.
- Right-click it and select "Properties".
In the pop-up window, take a look:
- Whether the "Start Type" is "Auto (Delayed Start)" or "Auto";
- Whether the Service Status is "Running".
If not, you can:
- Click the "Startup Type" drop-down menu and change it to "Auto (delayed startup)";
- If the service is not running, click the "Start" button to let it run.
If an error is reported after clicking "Start", it may be other problems, such as permissions or system files corruption.
2. Use the system-owned troubleshooting tool
Windows comes with a widget that is specifically used to troubleshoot update-related issues.
- Open Settings → System → Troubleshooting;
- Find "Other Troubleshooting" or search directly for "Windows Update";
- Click Run, the system will automatically scan and try to fix the discovered problems.
This method is suitable for friends who are not very familiar with the command line. Although it is not omnipotent, it can sometimes solve problems quickly.
3. Rebuild Windows Update related components
If neither of the above methods works, you may have to do it and reset the core part of Windows Update.
Open a command prompt (administrator permissions):
- Press
Win Sto enter "cmd" and right-click to select "Run as administrator".
Then enter the following commands in turn (return once every line is entered):
net stop wuauserv net stop cryptSvc net stop bits net stop msserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msserver
The purpose of these commands is:
- Stop related services;
- Rename two key update cache directories (equivalent to clearing the cache);
- Restart the service again.
After the execution is completed, restart the computer and try to check for updates normally.
4. Check whether the system files are corrupted
Sometimes system files are corrupted, which can cause the Windows Update service to fail to start.
You can use the system's own sfc and DISM tools for repair:
Also run in the administrator command prompt:
sfc /scannow DISM /Online /Cleanup-Image /RestoreHealth
The former is to check the integrity of the system file, and the latter is to download a clean system image from the Microsoft server to repair the corruption.
These two processes may take a little time, and then go back and see if the service can be started after completion.
Basically these common ways of dealing with it. Sometimes it can be done with one of the steps, and sometimes it takes all of them. Be careful not to interrupt during operation, especially when running system repair commands.

Windows stuck on 'undoing changes made to your computer'
Jul 05, 2025 am 02:51 AM
The computer is stuck in the "Undo Changes made to the computer" interface, which is a common problem after the Windows update fails. It is usually caused by the stuck rollback process and cannot enter the system normally. 1. First of all, you should wait patiently for a long enough time, especially after restarting, it may take more than 30 minutes to complete the rollback, and observe the hard disk light to determine whether it is still running. 2. If there is no progress for a long time, you can force shut down and enter the recovery environment (WinRE) multiple times, and try to start repair or system restore. 3. After entering safe mode, you can uninstall the most recent update records through the control panel. 4. Use the command prompt to execute the bootrec command in the recovery environment to repair the boot file, or run sfc/scannow to check the system file. 5. The last method is to use the "Reset this computer" function
