How to Fix Error 0x80070005 and Upgrade to Windows 10 or 11 Pro

Fix Error 0x80070005

Important note: your files will be deleted, we recommend that you make a backup before proceeding with the steps below.
  1. First, you must open the start menu, search for “ Registry Editor ” or “ Regedit ” and then navigate to the following key:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\
  2. Double-click “ ProductName ” in the right pane and change the value from “Windows 10 Home” to “Windows 10 Pro” or change it to “Windows 11 Pro” if you are trying to fix Windows 11.


The next step is a factory reset of your computer, where Windows will be tricked by the registry hack into thinking you are already using Windows 10 Pro and have configured everything for you.

  1. Open the Settings app, press Windows + I keys, and go to Update & Security > Recovery or type “ Reset this PC ” in the search box.
  2. Tap the “ Get Started ” button under “ Reboot this PC ”, choose the “ Keep my files ” option (unless you want to delete all your files), and proceed with the wizard to do a complete factory reset of your PC.
Note: If you are presented with the option to download the installation files to the cloud, choose that option.
