Why Windows 11 update stuck?

There are so many reasons that might cause this problem, but some are typical:

▶ Slow internet connection
It is the core cause of the majority of 'updates getting stuck' problems. The same holds when installing the Windows 11 upgrade. In addition to being a cause, an unstable internet connection can give rise to additional causes. The unstable internet connection may create an error in the update's downloading process, or the downloaded files may be damaged, causing the update to become stuck.

▶ Unstable Power Supply
It's not as common as the other factors, but an unstable power supply might cause Windows 11 updates to become stuck on your computer. When the Windows 11 update is installed, the unreliable power supply can interrupt the installation process, so the update is stuck.

▶ Lack of drive space
Windows updates, particularly version upgrades such as Windows 11, require a lot of space to install. Windows 11 ISO is over 4.5GB in size. It will first be downloaded to the system drive and then decompressed before the update procedure can begin.Insufficient storage space on the system drive may be one of the causes of the Windows 11 upgrade being stuck. So, before you begin upgrading, ensure sure you have adequate storage space to complete the procedure.

▶ Corrupted update files
The ISO file is critical in the Windows 11 installation process, and if it is damaged, the installation process would be hampered.

How to fix Windows 11 update stuck problem

After you know the possible reasons that may cause this problem, now, let’s solve Windows 11 update stuck at 100% or any certain percentage.

Step 1. Go to Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters.

Additional troubleshooter

Step 2. In the Additional troubleshooters window, find Windows Update, click on it and then click Run the troubleshooter.

Step 3. Wait for the troubleshooter to look for any issues and fix the issues it finds. Then, restart your PC and the update should download and install now.

Way 3. Extend system drive

Check your C drive, if it doesn't have enough space, you may make more by rearranging partitions, moving certain software, and emptying your download folder.

And if you open Disk Management and find that there's unallocated right behind the C drive, then you can use "Extend Volume" to extend C drive space. However, if the unallocated space isn't adjacently on the right of C drive or there's no unallocated, don't worry, you can use AOMEI Partition Assistant Professional to easily fix this issue.

It’s Windows disk/partition management software that allows you to merge unallocated space to another drive even if they are nonadjacent and directly share free space from one drive to another.
