If a windows takes to much CPU usage and runs endless the following trick may help:
- run the tool ‘msconfig’
- disable the option ‘Benutzerdefinierter Systemstart’ -> ‘Systemstartelemente laden’
- select under ‘Dienste’ the option ‘Alle Microsoft Dienste ausblenden’
- deselect all ‘Dienste’

When all updates are finished successfully the option “normaler Systemstart” can be enabled again in the msconfig Tool.
