Why Does The Windows 11 Update Get Stuck (Causes)?

Several factors can be responsible for causing this issue, and the type of approach needed to fix them also differs. It could be your internet connection that is making download longer or you may run out of storage space in between updates and so on. 

Unstable Internet Connection

It is the cause that is responsible for most of the 'updates getting stuck' issues. The same goes for the installation of the Windows 11 update as well. Unstable internet connection, aside from being a cause itself, can give birth to even more reasons. The unstable internet connection can lead to an error in the downloading process of the update, or the downloaded files may be corrupted, which may cause the update to get stuck. 

Unstable Power Supply

Although not as frequent as other causes listed in this section, the unstable power supply can also cause Windows 11 updates to get stuck on your PC. Windows 11 update installs on boot. If the power supply is unstable, it may interrupt the installation process, leading to the update getting stuck at a certain level. 

Insufficient Storage

Windows updates, especially version upgrades like Windows 11, need plenty of space to install. The ISO of Windows 11 is over 4.5GB.  It will be first downloaded on the system drive and then decompressed to start the update process. One of the causes of the Windows 11 update getting stuck can be insufficient storage on the system drive. So make sure before you start updating, clear out enough storage space for the process to complete.

Corrupted ISO File

An unstable internet connection may cause this, but sometimes the downloaded file itself is corrupted. The update process can get stuck if the Windows ISO file is corrupted or isn't compatible for some reason. The ISO file is of utmost significance in the installation process of Windows 11, and if it's corrupted, the installation process will face certain obstacles.

How Do I Know If My Windows 11 Update Is Stuck?

It is essential to verify that the Windows 11 update is stuck before jumping to conclusions and trying solutions to fix it. Here are some of the known symptoms that hint at a stuck update installation process:

1. Stuck At Downloading:  0%, 90%, 100%, etc. or it's not progressing

If your Windows 11 update is stuck at a certain percentage of the files downloaded in the downloading part of the whole process, it might hint at a stuck update installation process. Wait for some time to verify if your download seems stuck at a certain level or hasn't progressed at all, even when your internet connection is fine. 

 2. Windows 11 download completes at 100% but doesn't go to the next stage, hangs for hours.

It is safe to assume that your Windows 11 update is stuck if the download is 100% complete and nothing happens for hours. Usually, you'll be taken to the next stage once you reach the 100% download mark, but if that doesn't happen and your PC stays hanged for a long time, you may have to restart the process.

3. Windows 11 update takes hours but doesn't move at all

The Windows 11 update process may take some time to complete, but it doesn't take hours. If your update takes hours to install, it might be stuck, and you need to try the solutions listed in this article to fix the issue.

How Do I Fix Windows 11 Update Stuck (0%, 11%, 99%, 100%) Issue

As mentioned earlier, depending on the cause of the issue, the approach needed to fix it might differ. Before we take a look at the real solutions, here are some quick tips that you can try:

  •  Disable and Enable Windows Update Service
  •  Reset Windows Update Components
  •  Turn Off Firewall Temporarily
  •  Unplug External Storage Devices

If these tips aren’t working for you, here are some more impactful ways to fix the issue. Follow them one by one, and always check if the update has started progressing after every section.

Method 1: Check and Fix Unstable Network Connection, Power Supply

We discussed earlier that an unstable internet connection and an unstable power supply might lead to the Windows 11 update getting stuck. Here the things you can try to check and solve these problems:

Unstable internet connection: Check your internet connection. If it is fine, then disconnect your PC, restart it and connect again. Use an ethernet cable if it is an available option. The chances of Windows 11 update getting stuck on a stable internet connection are low. Try connecting to a different network. You've to make sure the PC is connected to a stable internet connection while undergoing the update installation process.

Unstable power supply: This can lead to Windows 11 update getting stuck as well. Disconnect your PC from the power supply and check it thoroughly. Once you're sure that the power supply is fine, re-plug your PC and check again. Look for a different power source if the one you've been using is even slightly unstable.

Method 2: Clear SoftwareDistribution Folder And Re-download Windows 11

Windows Update Agent is responsible for maintaining the SoftwareDistribution folder, a significant folder for Windows 11 updates. Usually, there is no business with this folder, but there might be a need to clear its contents to force Windows to start downloading updates again. Windows will re-download all of the content of this folder when it sees nothing is there, on its own later. So you don't need to worry about anything. Follow the steps listed below carefully to clear the SoftwareDistribution folder safely:

Reset Windows Update Service

  • Open Start and search for Command Prompt. Right-click on it and click on Run as administrator.
  • Type the command: net stop wuauserv and press the Enter key. It will stop the Windows Update Service.
  • Type the command: net stop bits and press Enter. It will stop the Background Intelligent Transfer Service (BITS)
  • Open This PC by pressing Windows + E and navigate to this location: C:\Windows\SoftwareDistribution
  • Select all of the contents you see in the SoftwareDestribution folder by pressing Ctrl + A and delete them. Restart the computer and repeat the process mentioned if you encounter any trouble while deleting the files.

Next, we need to start the two services that we stopped at the beginning of this process. 

  • Type this command in the command prompt and press Enter: net start wuauserv
  • Type this command and hit Enter: net start bits

Re-download Windows 11. Make sure to verify files and download them on a stable internet connection. 

Method 3: Extending System Partition With Sufficient Space

Check your C drive or where Windows is available; if it has enough space left for installing the Windows 11 update. If it doesn't have enough space, you can add more space by altering partitions or uninstalling some of the applications and clearing your download folder.

Many software available on the internet will help you with that, but we recommend using the EaseUS Partition Master. Using the EaseUS Partition Master, you can easily extend the storage of your C drive and proceed with the Windows 11 update process without any issues.

Step 7. The computer will boot using the USB drive, and Windows 11 installation should begin. Make sure to select the same system drive where Windows 10 was installed. If you are doing it on a new PC, then make sure you have enough storage. Follow the wizard, and complete the installation process.
