It seems that Microsoft has acknowledged this issue (see my earlier post), and published this workaround.
You can resolve this problem by setting some services to Automatic (Delayed Start) and restarting Windows:
Press the Windows Key and R at the same time to bring up the Run dialog. Type services.msc in the Run dialog and press Enter.
For each of the following services, locate the service in list, right-click the service and select Properties. Then set the Startup type to Automatic (Delayed Start) and select Apply.
