Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.
When users try to log on to Windows Server 2008 or Windows Vista SP1 systems, the User Profile Service crashes. This problem occurs if the profile that the service tries to load or to unload contains compressed files or compressed folders.
Additionally, the following services also crash:
Background Intelligent Transfer Service
Group Policy Client
Health Key and Certificate Management
IKE and AuthIP IPsec Keying Modules
Multimedia Class Scheduler
User Profile Service
Remote Access Connection Manager
System Event Notification Service
Terminal Services Configuration
Shell Hardware Detection
Windows Management Instrumentation
This issue occurs because the User Profile Service (ProfSvc) uses an incorrect synchronization method to set the compression flag in user profiles. Therefore, the User Profile Service encounters an access violation and then crashes.
The User Profile Service and the other services that the "Symptoms" section mentions share one Svchost.exe process. Therefore, when the User Profile Service crashes, all the other services that the "Symptoms" section mentions also crash.
