New installation of W10 and W8.1 is failing.
New installation of W10 and W8.1 is failing.
Earlier today I set up a W10 insider version 10130 and used my w8.1 activation key. It turns out this build has a problem—it won’t automatically upgrade to newer versions. So I had to copy the W10 release build to my USB drive and perform a fresh installation. When trying to activate with the w8.1 key, I receive an error code 0xC004C003. Microsoft support isn’t helping; they suggest installing the w8.1 version first and then upgrading, even though the key worked perfectly on the insider build. I’m stuck because I don’t have space for the “windows.old” folder on my SSD.
