Yesterday, when updating two PCs at the office, the SVCHOST.exe was using 100% of the CPU for a long time. There seems to be a fix for this but you have to get in contact with Microsoft. According to the KB article: 916089 it happens when you run Microsoft Update or apply updates to any applications that use Microsoft Windows Installer (MSI) 3.1 together with Windows Update. Additionaly you may receive the folowing error in the Event Viewer:
Application popup: svchost.exe – Application Error : The instruction at “0x745f2780″ referenced memory at “0x00000070″. The memory could not be “read”.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes. Apply it only to systems that are experiencing this specific problem.
To resolve this problem, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:
