You need to have the following on your Windows Home Server:
- Download and install Microsoft’s Process Explorer
The first step is to suspend the SBCore service process in Process Explorer:
- Launch Process Explorer
- Right-click sbscrexe.exe and select Suspend
Once the process is suspended, the service can be disabled in the registry:
- Launch the registry editor (Start → Run… → regedit)
- Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SBCore
- Right-click the key and select Permissions…
- Add the local Administrators group, give it Full Control and press OK
- Press F5 to refresh the view and show all the values under that key
- Double-click the Start value
- Change the Value data field from 2 to 4 to disable the service
- Close regedit
In order to prevent the service from restarting itself, perform the following steps:
- Open Windows Explorer and navigate to C:\Windows\System32\
- Right-click sbscrexe.exe and select Properties
- Select the Security tab
- Add the Everyone group, Deny all access and ignore the warnings
Last but not least, terminate the suspended process in Process Explorer:
- Right-click sbscrexe.exe and select Kill Process
The SBCore service should now longer be running or restarting itself.
The solution was first discussed in a Speed Guide Forum post in the context of Small Business Server 2003, from which Windows Home Server inherits some of its functionality.
What is SBCore? is a related discussion on the Microsoft forums.
