Windows 10: I get an 0xc1900201 error when updating windows 10 "can't install windows 10 to a flash...

I get an 0xc1900201 error when trying to update windows 10, it also says "can't install windows 10 to a flash drive using setup". I don't have anything plugged into my computer! Only the ethernet cable. I have version 1703 and am trying to upgrade. Can you help me? I tried renaming the Softwaredistribution file but couldn't. It kept telling me the file was in use by another program and I needed to close it first, but nothing else was running!

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Is it time for Windows 10 already?

Again, for those that want the update reservation and you meet the requirements ---> Upgrade to Windows 10 for Free

And, some info from the FAQ page:

Also, some interesting info from the Specifications page:
