- Windows Update stuck at 0% may be due to many factors affecting the Windows Update service on your PC.
- Network issues can also cause the Update to get stuck or frozen.
- Deleting the Windows Update cache folder in your File Explorer can fix the problem.
Many problems may arise when downloading or installing Windows Updates on your computer. First, they impede the update process, resulting in the Windows Update being stuck at 0 during download & installation.
Another instance of this problem is Windows Update stuck at 100%, meaning it won’t completely download.
Windows Updates require some essential services and components to function correctly. When these components are not intact, the Update may get stuck or fail. The most common reason is a conflict with some programs on your PC. For example, programs like Windows Defender can impede the Update process.
Many other factors can cause the Windows Update to be stuck or frozen. Some are:
- Network issues – When there’s a problem with your network connection, it’ll affect the download process of the Windows Updates. The network congestion on your PC can leave no bandwidth for Windows Update services to use, resulting in the update getting stuck or frozen.
- Issues with Windows Update services – Windows Updates can get stuck during initialization or finalization if the Windows Update services on your computer are not intact. These services are responsible for processing and initializing the Updates on your device.
- Windows Update cache – The Update cache on your PC may be old or corrupt, causing issues with the Update files in the folder. Hence, it blocks the process, resulting in the Windows Update being stuck.
These causes can vary in computers, meaning they can demand different fixes. Fortunately, we have some general solutions to help install your Windows Updates.
