Is the KMS setup key from Microsoft’s website a free license?

No. It is a generic installer key that only points the server at a KMS activation host. Without a KMS server on your network it activates nothing. Permanent, standalone activation requires a retail or OEM key.

Do I still need CALs with a Standard key?

Yes – Windows Server 2022 Standard requires User or Device CALs for clients that access the server, separate from the license itself. Essentials bundles its own simplified CAL.

Is buying Windows Server 2022 still worth it in 2026, so close to mainstream end?

Yes for most on-prem workloads: security updates run to October 2031 under extended support, and the license includes upgrade rights to Windows Server 2025. Budget accordingly for the 2025 in-place upgrade when the time comes.

How many VMs can I run with one Standard license?

Two virtual machines (or two OSEs) on fully licensed hardware, plus the physical host itself. Beyond that, additional Standard licenses or a Datacenter license cover the extra VMs.

My server shows “not activated” after months of working. What happened?

That pattern matches a voided volume-license batch or a hardware change. Note the exact error code, check whether your seller’s guarantee covers replacement, and try phone activation once before repurchasing.
