Updating pirated xp
Microsoft just wants to bug you into using a legitimate version of Windows and buying a legitimate product key.
This feature also prevents smaller computer manufacturers from installing pirated copies of Windows on their PCs and selling them to unsuspecting buyers.
If you install a different copy of Windows on a PC that came with an OEM Windows key, you’ll have to go through the standard Windows Product Activation process.
The OEM activation process only works when you use the copy of Windows that came with your computer or restore that original copy of Windows.
This feature works similarly, but Office will only function in read-only mode if it hasn’t been successfully activated.This is an anti-piracy feature — it’s designed to annoy you if you’re using a non-genuine copy of Windows.Luckily, Windows Activation has been toned down after its introduction in Windows XP.Apple makes no representations regarding third-party website accuracy or reliability. Windows Activation, introduced in Windows XP, checks in with Microsoft when you install Windows or get a new Windows PC.
