Need help with Windows Error C1900204

Bleda412 · March 5, 2016

Okay, I have tried to upgrade to Windows 10, and it says there is an error. I of course looked it up on my own, but the only solutions were for Windows 8. Trying to follow the same steps didn't get me anywhere (iirc since i tried this last one month ago).

Have you changed the default install location like this guy with the similar error had? https://answers.microsoft.com/en-us/windows/forum/windows_10-win_upgrade/update-failed-error-code-c1900204-fixed/d65366a8-7926-4784-af17-516762bbeb51?auth=1

If so, change it back and try again.

Usually a brute but foolproof trick works: A clean install instead of an upgrade.

Get the USB installer instead of the in-OS installer. You can get the USB creation tool here. Boot the machine off of the USB and do a clean install. You can use the license key for 7 or 8 or 8.1 during the installation. This method will completely eradicate all the data on your installation partition so do backups beforehand.
