However, more often than not, the Upgrade Assistant folder is confused for the Windows.old folder. If that's the case or if you don't like this folder sitting in the root of your C drive then you can simply delete it.
Without ado, let me show how you can delete the Windows10Upgrade folder in Windows 10.
Steps to Delete Windows10Upgrade Folder
In general, since the folder is created by the Upgrade Assistant application, you should not delete the Windows10Upgrade folder directly. If you do try to delete it directly, it might throw Access Denied error or make the Upgrade Assistant application act unpredictably. So, what you have to do is, uninstall the application and then delete the folder. Let me show you how.
1. First, open the "PC Settings" app by pressing the Win + I keyboard shortcut. In the app, go to the "Apps → Apps & Features" page.
2. On the right panel, scroll down till you find the Windows 10 Upgrade Assistance application. You can also make use of the search bar to make things easier.
3. Click on the Upgrade Assistant option and then click on the "Uninstall" button.
4. Click on the "Uninstall" button again in the pop-up.
5. Go through the wizard to complete the uninstallation procedure.
6. Now, open the File Explorer by pressing Win + E and go to the C drive.
7. Here, see if you have the Windows10Upgrade folder. By default, the folder should be automatically deleted when you uninstall the Upgrade Assistant application. If not, simply select the folder and press the Delete key on your keyboard.
If you see any error messages while deleting the folder, reboot the system and try again. Sometimes, even after uninstalling the Upgrade Assistant application, the folder might still be in use in the background. Rebooting will fix the issue.
