Is buying an OEM key online legal?
الإجابة المختصرة
Yes in most countries — Microsoft sells OEM keys to system builders, and reselling unused, unbound OEM keys is permitted in the EU under the UsedSoft v Oracle ruling (CJEU C-128/11). In the US, OEM keys are legal once detached from the original system as part of a single transfer.
الشرح المطوّل
Microsoft's End User License Agreement allows the original purchaser of a Windows OEM license to transfer it once, in its entirety, to another party. Unused keys that were never activated on a specific motherboard are treated under the EU first-sale doctrine as resellable goods.
Risk indicators when buying: keys priced under €15 for Windows 11 Pro, no email receipt, no invoice, marketplace sellers with no contact address. Legitimate resellers offer a money-back guarantee and a written replacement policy.

What's the difference between Office 2024 and Microsoft 365?
Office 2024 is a one-time purchase that locks the apps at their October 2024 version forever. Microsoft 365 is a subscription that includes the same apps plus 1 TB OneDrive, monthly feature updates, Outlook with email hosting (Business plans) and Copilot eligibility — but stops working when you cancel.
How many PCs can I install one Office licence on?
Perpetual Office (2021/2024 Home & Student / Home & Business / Pro) activates on exactly one PC and is transferable to a new PC if you uninstall on the old one. Microsoft 365 Personal allows install on unlimited devices but sign-in on five at a time; Family allows the same for six users.
How do I fix Windows activation error 0x80072F8F?
0x80072F8F is a TLS clock mismatch — Windows can't validate Microsoft's activation server certificate because the system date is wrong. Open Settings → Time & Language → Date & Time, enable 'Set time automatically' and 'Set time zone automatically', then re-run activation.
Can I install Windows 11 without TPM 2.0?
Technically yes via a registry bypass during setup, but Microsoft explicitly does not guarantee security updates on unsupported hardware. Most 2018+ PCs have an fTPM in BIOS that just needs enabling — check before bypassing.
