When a computer group is created in Essentials 2010 using Create a Computer Group in the Computers space, a corresponding group is created in the WSUS database. This can be seen in the WSUS console.
Figure 1. Computer groups in the WSUS console.
Deleting these computer groups from the WSUS console will result in the computer group not showing in the Computers space.
Use this tool if you no longer see some or all computer groups in the Essentials console that you had previously created.
