Hi All,
One of my PCs needed to be reformated. It had Win 10 Pro previously and activated from Win 7 product key (when free upgrade was still a thing).
I couldn't remember how I reformatted it, but I think it was from the recovery mode or repair option after the BIOS or something like that.
Since I reformatted the PC, now on the bottom right it has "Activate Windows" watermark, which is annoying.
Went to Settings to activate then put previous key (win 7 admittedly), did not work.
Is there a way for me to activate this Win 10 installation now other than buying win 10 pro key which is expensive?
If the only option for me is to buy the key, what's the cheapest way to get it?
Tia!
You can usually call a number and have it activated that way.
To activate Windows 10 by phone:
Select Start > Settings > Update & Security > Activation.
Under Activate Windows Now section, select Activate by Phone.
Select your location (or the location nearest to you) from the drop-down list, and then select Next.
Call one of the available phone numbers listed. An automated system will guide you through the activation process.
If you're not able to complete activation successfully, you will be connected to Microsoft support for your region and country.
It's a fairly quick process (5 minutes to do) and should work pretty much instantly, assuming the license key you provide is a legit one.
Note: it'll also help that you're signed into a Microsoft account, as opposed to a local account. In Win 10 onwards, Windows sometimes is activated with a digital license linked to your Microsoft account. Try Logging into your account and then rebooting, see if that helps.
