Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.

 

Windows 10 Activation (Insider)

I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

 

Windows 10 Activation (Insider)

Hi!

I signed up in the windows insider program and got windows 10 free - the windows 10 insider preview updated to windows 10 pro.
Today i got another SSD and did a raid 0 on my system forcing me to do a clean install of windows but now it wont activate anymore.
Signing in with my microsoft account that was linked to the insider program didnt help.
Maybe i got this problem since i quit the insider program for several days and signed up again after i found out that my win 10 wont activate anymore.
Any ideas how to fix it?
