Frequently asked questions

Windows Server 2025 Standard or Datacenter?
Standard covers one physical server and up to two Windows Server virtual machines: the right choice for a file server, a domain controller or a business application. Datacenter allows an unlimited number of virtual machines, for a heavily loaded Hyper-V host. Rights also depend on the number of cores: check them above 16 cores.
What are the minimum requirements?
According to Microsoft: a 64-bit 1.4 GHz processor supporting the SSE4.2 and POPCNT instructions, 2 GB of RAM for the installation with a graphical interface and at least 32 GB of disk space. A TPM 2.0 chip and Secure Boot are required for some security features.
Can I upgrade a 2019 or 2022 server?
Yes, Windows Server 2025 supports in-place upgrades from Windows Server 2012 R2 and later versions. Make a full backup before you start and check that your business applications are compatible.
Do I need CALs for Remote Desktop?
Yes, beyond the two administration sessions: one RDS CAL 2025 per user or per device. CALs from an earlier version do not work with a 2025 server.
How do I activate the key?
Settings > System > Activation, or the command slmgr /ipk followed by the key in an administrator command prompt. A server installed from an evaluation version must be converted first; if in doubt, write to us before buying.
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 Server 2025 is the current generation, released at the end of 2024 and supported by Microsoft into the 2030s, which makes it the sensible choice for a server you intend to keep for a decade. Chkey.ch offers Standard and Datacenter licences at Swiss prices.

This release brings hotpatching, which applies certain security updates without a reboot, along with SMB over QUIC, GPU partitioning for virtual machines and an Active Directory rebuilt on larger database pages. Datacenter lifts the virtual machine limit, Standard covers two guests per licence, and Remote Desktop CALs are sold separately.
