You’re not alone if you’re having trouble with Windows updates getting stuck at 0% while downloading or installing. This is a common error that many Windows users face, but the good news is that it’s typically easy to fix. In this article, we’ll explain the possible causes of this computer problem and offer several solutions to help you get your Windows software upgrades downloading and installing again.
What Causes Windows Update Installation or Download to Get Stuck or Freeze at 0%?

First, let’s discuss the potential causes of this PC problem. Most updates that are stuck at 0% are caused by one of the following factors:
– Insufficient disk space: Windows updates require a certain amount of free space on your hard drive in order to download and install properly. If you don’t have enough free space, the update process may get stuck.
– Network or internet connectivity issues: If you’re having trouble connecting to the internet, or if your connection is slow or unstable, this can prevent the update from downloading properly.
– Problems with the Windows Update service: The Windows Update service is responsible for downloading and installing updates on your computer. If this service is not running properly, or if it’s been disabled, you may experience problems with upgrades.
– Corrupted update files: In some cases, the update files that are downloaded to your computer may become corrupted, which can cause the upgrade process to get stuck.
How to Troubleshoot the Issue & Fix Windows Updates Stuck at 0% Downloading or Installing Error

Now that we’ve discussed the potential causes of this PC software upgrade issue, let’s move on to the solutions. Here are some things you can try to fix Windows updates stuck at 0% downloading or installing:
Solution #1 – Check for Sufficient Disk Space
As mentioned above, you need to have enough free space on your hard drive in order to download and install updates properly.
- To check for sufficient disk space, go to the Start menu, type “disk cleanup” into the search box, and then press Enter.
- This will open the Disk Cleanup utility, which will allow you to free up space on your hard drive by deleting unnecessary files.
Solution #2 – Restart your Computer and Router
If you’re having connectivity issues, restarting your computer and your router can sometimes fix the problem.
- To restart your computer, click on the Start menu, click the power icon, and then click “Restart.”
- To restart your router, unplug it from the power source, wait a few minutes, and then plug it back in.
Solution #3 – Check the Windows Update Service
As mentioned earlier, the Windows Update service is responsible for downloading and installing updates on your computer.
- To check the status of this service, go to the Start menu, type “services” into the search box, and then press Enter.
- This will open the Services utility, where you can see the status of the Windows Update service.
- If it’s not running, you can start it by right-clicking on it and selecting “Start.”
Solution #4 – Run the Windows Update Troubleshooter
If you’re still having trouble with updates getting stuck at 0%, you can try running the Windows Update troubleshooter. This is a built-in utility that can help you identify and fix problems with Windows updates.

Solution #5 – Reset the Windows Update Components
If none of the above solutions have worked, you can try resetting the Windows Update components. This will delete any existing update files on your computer and allow you to start fresh with the upgrade process. To reset the Windows Update components, you’ll need to open a command prompt as an administrator.
- To do this, go to the Start menu, type “command prompt” into the search box, and then press Enter.

To reset the Windows Update components, you’ll need to enter the following commands, pressing Enter after each one:
- net stop wuauserv
- net stop cryptSvc
- net stop bits
- net stop msiserver
- ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
- ren C:\Windows\System32\catroot2 catroot2.old
- net start wuauserv

After entering these commands, close the command prompt and try downloading and installing updates again.
In conclusion, if you’re having errors and problems with Windows updates getting stuck at 0% while downloading or installing, there are a few solutions you can try.
