Hi HINGEX,

It's a complicated case, since Microsoft no longer reissues keys for out-of-support products; replacing or upgrading to a supported Windows Server is the recommended long-term solution for production systems. But here are some of my suggestions you can consider trying to recover or replace the key.

1/ Quick checks

• Look for the COA sticker on the server, original media packaging, purchase invoice, or vendor email.
• If your org used Volume Licensing, check VLSC or ask your licensing admin.

2/ Recover from the running system (it's the fastest way)

• Run a trusted local tool (for example NirSoft ProduKey) as Administrator to read and decode the installed product key from the registry.
• If the system won’t boot, export the SOFTWARE registry hive and run the same tool on another trusted PC.

If you cannot recover locally

• Contact the original hardware vendor/OEM or your reseller to check purchase records or COA reproduction.
• If you have enterprise licensing, ask your Volume Licensing administrator to retrieve or reassign a key.
