Could your Windows 10 Pro license be shared or misused by someone else?
Could your Windows 10 Pro license be shared or misused by someone else?
You have the possibility of it being used on other devices. Since you created an offline install without a Microsoft account, tying it to an online account might help keep it exclusive to your setup. However, checking past installations could still reveal if someone else accessed the key before.
The sticker applies to an 'OEM' license for Windows 10. Currently, it seems transfers aren't possible between devices, even with different storage drives. In real-world use, as long as you possess valid Windows 10 keys (either OEM or retail) linked to your Microsoft account, you should face no licensing or activation problems regardless of the computer you're using.
It started as a sticker, so it's improbable it's found elsewhere.
In that scenario, they would have recorded notes on paper and erased them. Still, very improbable.
