Hello,
Windows was not pre-activated, after install, connect to internet, reboot - not activated. Used HWID from Medicines folder, works fine.
Every other Rain version of win10 i used was alright and activated as soon i connected to internet. Didnt even need to reboot. Installed on over 100 laptops.
Last one i used Windows 10 Pro 19h1 v.1903.18362.145 En-us x64 May2019 V.3 Pre-Activated-=TEAM OS=-
I think someone else said in comments it didnt auto activate...
