Frequently asked questions
Windows 11 Home or Pro: which should I choose?
Home is enough for personal use: browsing, office work, gaming. Pro adds BitLocker encryption, remote access to your PC (Remote Desktop), Hyper-V and advanced update management, which are useful for freelancers and SMEs. See Windows 11 Pro OEM and Windows 11 Home OEM.
OEM or Retail key: what is the difference?
Same software, same updates. An OEM key is tied to the first computer it is activated on; a Retail key can be moved to another PC if you stop using it on the old one. If you plan to change your computer or motherboard, choose Windows 11 Pro Retail. Find out more: OEM or Retail and Windows and the motherboard.
Is my computer compatible with Windows 11?
Windows 11 requires, among other things, a TPM 2.0 chip, Secure Boot and a processor supported by Microsoft. Microsoft's free "PC Health Check" app tells you in a few seconds whether your computer meets these requirements.
How do I activate my Windows 11 key?
Open Settings > System > Activation, click "Change product key" and enter the 25 characters you received by email. An Internet connection is required. If your PC runs Windows 11 Home, a Pro key upgrades it without reinstalling. Some keys are activated by phone: see the guide.
When will I receive my key, and what if it doesn't work?
By email, within 24 hours of payment, together with your invoice (please also check your spam folder). If the key does not activate, let us know within 7 days at support@chkey.ch: after checking, we replace it or refund you. Details: Shipping & Returns.
