Cannot delete WSUS role on SBS 2008

Trying to fix WSUS on SBS 2008 server, I followed https://technet.microsoft.com/en-us/library/dd939818(v=ws.10).aspx and ran the commandmsiexec /x {BDD79957-5801-4A2D-B09E-852E7FA64D01} callerid=ocsetup.exe

I'm still receiving error 0x80070643 with MessageCode: -2147023293 when trying to delete WSUS role from SBS 2008 server.

The worst, I lost access to SharePoint Services.

Any idea how could I get back Windows Internal Database, or fix suppression of WSUS role from SBS 2008 in order to reinstall after the role?

Thank you
