Buy Windows 10
Windows 10 Home and Pro keys in Switzerland, as OEM or Retail versions, plus the Education and Enterprise LTSC editions. A solution for computers that do not meet the Windows 11 requirements. Key by email within 24 hours with an invoice, payment in CHF by TWINT or card. Before buying, read the FAQ on the end of support.
Microsoft ended support for Windows 10 Home and Pro on 14 October 2025. The system still installs, activates and works normally, but no longer receives free security updates. For a computer used online every day, we recommend Windows 11 if the PC is compatible. The Enterprise LTSC editions follow their own support schedule.
When does Windows 10 still make sense?
For a PC that cannot move to Windows 11 (no TPM 2.0 chip, processor too old), for business software or a device that only works on Windows 10, or for a machine that stays offline. Microsoft's free "PC Health Check" app tells you whether your computer supports Windows 11.
Home or Pro?
Home covers personal use. Pro adds BitLocker, Remote Desktop, Hyper-V and joining a domain. A Pro key upgrades a PC running Home without reinstalling.
OEM or Retail key?
An OEM key stays tied to the first PC activated; a Retail key can be moved to another computer. If you plan to change your motherboard or PC, choose Retail. Explained here: OEM or Retail.
How do I activate my Windows 10 key?
Settings > Update & Security > Activation > "Change product key", then enter the 25 characters you received by email, with an active Internet connection. For phone activation: 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.
Windows 10 remains a reliable, stable and well-supported operating system — ideal for giving an older computer a second life or equipping a machine that doesn't meet Windows 11's requirements. Chkey.ch offers Windows 10 Home and Pro licences at Swiss prices.
Activation happens directly from Windows settings, within minutes, with no reinstall needed if the system is already in place.
