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.

 

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

 

Windows 10 pro activation

Hello all,

I have recently purchased Surface pro 4, but my system throws an activation message informing to activate the windows 10 pro. On attempt to activate my system is displaying another error message informing that system does not have valid digital licence.

My question is ,on purchasing a new device is windows 10 pro will be pre-activated and installed ?

Also suggest me some solution to solve this problem.

Thanks in advance
