So I upgraded last night to the RC of Windows 7.
I took longer than the previous builds to upgrade but that’s possibly because I had the files from ISO on the HDD I was upgrading. It wasn’t my fault I needed to change the MinBuild string to let me upgrade from 7068 though.
So first impressions? Not really any difference from the 7068 build with the exception of the changed desktop version printout. SideShow still seems to be missing, and I’ve emailed the SideShow team to ask them about this, so hopefully I get a positive response back like it will be back in the RTM build.
