Friends,
STOP PIRACY of Windows 10 Pro.
You can buy Windows 10 Pro OEM keys as low as ₹1000/- each!
I personally used 8 keys and all are work fine for 3 year+
You can NOT change the Motherboard and Processor TOGETHER.
Processor upgrade is also allowed, no issue.
If you are interested, then post here.
Pls Note:You MUST need to have fresh Windows 10 Pro Installed WITHOUT any key. Then activate Windows using the new Key.
