Contrary to the popular belief, the luck doesn’t have anything to do with the preference of Windows 10 upgrades. Users who get the updates before the general population, avoid OTA and stick with the Upgrade Assistant. This tool is great to install major updates just after the release. However, some of those users are, seemingly, unable to upgrade their system with the Upgrade Assistant. There’s the reoccurring error which prevents them from finalizing the installation process.
How to fix Upgrade Assistant error in Windows 10
- Make sure you meet the requirements
- Run Update troubleshooter
- Disable third-party antivirus and unplug the peripherals
- Use the Media Creation Tool
- Repair previous Windows 10 installation
- Perform a clean reinstallation
1: Make sure you meet the requirements
Firstly, let’s start with the essential reminder. When we say to meet the requirements, we mostly refer to storage space. You’ll need at least 16 GB of free space to install a Feature or Major update. In addition, we encourage you to double-check the drivers and uninstall third-party applications. This isn’t needed by default, but there are reports about third-party programs causing update issues.

Once you’ve done that, restart the update/upgrade process and look for changes. If the error is persistent, move on to the next step on the list.
2: Run Update troubleshooter
Windows 10 comes with the built-in troubleshooter for all system-related features. That includes the Windows Update troubleshooter. This is, probably, the most used troubleshooter due to the sheer number of update issues. Ideally, it would find and fix the problem causing the Upgrade Assistant error.
Follow these steps to run the Windows Update troubleshooter:
- Right-click Start and open Settings.
- Choose Update & Security.
- Select Troubleshoot in the left pane.
- Expand and run Windows Update troubleshooter.
- Follow the provided instructions.
3: Disable third-party antivirus and unplug the peripherals
We already mentioned the negative effect of third-party apps. The system should be able to upgrade without meddling with the installed software, but that doesn’t work every time. The programs that are especially causing errors are third-party antivirus solutions, which integrate deep into the system core. That’s why we suggest uninstalling them (or at least disabling) until the upgrade is successfully administered.
Furthermore, we also suggest unplugging all external hardware, with the mouse being the only exception. It seems there’s the stall leading to an error when the update fails to install the drivers for certain devices.
4: Use the Media Creation Tool
Now, there are multiple ways to install the same update. Besides the standard over-the-air update via the system and Upgrade Assistant, you have Media Creation Tool at your disposal, as well. This tool comes in handy when you need to create the installation media. However, you can also use it to download and install the update at hand. Be it a small patch or the major update. To do so, just download the tool, here. Accept the License terms and click Update now.

In addition, if this fails. You can create the installation media and install updates from there. Success or fail, you’ll be needing the bootable Windows 10 drive for the final two steps either way.
Here’s how to create the bootable media drive:
- Download Media Creation Tool from this link.
- Plug in the compatible USB flash drive with at least 6GB of free storage space.
- Run Media Creation Tool and accept the License Terms.
- Select ”Create installation media (USB flash drive, DVD, or ISO file) for another PC”.
- Choose the preferred language, architecture, and edition and click Next.
- Choose a USB flash drive and click Next.
- Wait until everything is done.
5: Repair previous Windows 10 installation
The most common critical reason for this occurrence are issues with the previous installation you made. Whether that was a failed major update or something else, we suggest repairing the system installation. If you’re able to access the system interface when the Upgrade Assistant error occurs, you should be able to reset your PC to factory values.
Here’s how to do it in a few simple steps:
- Press Windows key + I to open the Settings app.
- Choose Update & Security section.
- Select the Recovery from the left pane.
- Under the “Reset this PC” option, click Get started.
- Preserve your files and continue with the procedure.
In addition, you can boot from the bootable USB drive and load the installation files. Just, instead of going for the clean install, click on the Repair and repair the system.
6: Perform a clean reinstallation
In the end, if all of the previous steps fell short, the approach which remains is the clean reinstallation. With the clean reinstallation, you should be able to start from a scratch and the updates will be automatically administered during the installation. If you’re not sure how to perform a clean reinstallation of Windows 10, follow the steps we provided in this article.
