Basically there are two editions of Team Foundation Server, the Workgroup and Standard Edition. The workgroup edition is cheaper, but is limited to 5 connections.
I use my TFS primarily for small (hobby) test projects and to learn all about it. But I think i'm running out of licenses. So I was wondering which version of TFS I was running, Workgroup or Standard Edition.
You can find it in the Windows Registry on the TFS Server:
HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\VisualStudio
\8.0
\TeamFoundation
\Registration
The value in the key named 'Edition_CT' tells you about the edition. Note: changing this has no effect!
- "Full" = Team Foundation Server ("Standard Edition")
- "Trial" = Team Foundation Server 180-day Trial Edition
- "Workgroup" = Team Foundation Server Workgroup Edition
If you want to upgrade from Workgroup Edition to Standard Edition, all you need to do is run setup in Maintenance Mode and supply the product key for Standard Edition, which will lift the restriction of requiring users to be a member of "Team Foundation Licensed Users." (source)
