OK, as expected ID from Win 8.1 Pro is used here. With build 9860 it started to error when trying to avtivate via WMIC, so i would like to ask if you could check following activation command. Code: wmic path SoftwareLicensingProduct where ID='c06b6981-d7fd-4a35-b7b4-054742b7af67' call Activate Even if it can't contact a server it shows in Win 8.1: Code: C:\Windows\System32>wmic path SoftwareLicensingProduct where ID='c06b6981-d7fd-4 a35-b7b4-054742b7af67' call Activate Executing (\\S1AVE77-PC\root\cimv2:SoftwareLicensingProduct.ID="c06b6981-d7fd-4a 35-b7b4-054742b7af67")->Activate() ERROR: Description = But in mentioned build and 9878 it reports 'Invalid Class' error. In my tests even 'slmgr /ato' errored but still activated the system.

OK, so my assumption those 'PREVIEW' builds had been delivered broken was right. Nice to know, then my JATD, with slight adaptions to determine the build correctly, will work for this one (like for 9841) . Refused to download the broken builds, but now i know that i will download this one .
Only one thing i forgot . Is sfc /scannow adapted to recognize the new file compression/encryption or does it still give errors at the end ?
