Description: Provides management services for applications that require assistance in a multiple user environment. This service is responsible for activating the application compatibility shims for Fast User Switching. Fast User Switching allows multiple users to log on and run applications on a single machine. Some applications (usually non-Windows 2000 logo applications) are not able to run in this environment. We have created shims that allow these applications to run in a multiple user environment. This service only starts if there is more than one user logged on to the machine. It does not activate when there is only one user on the machine. Fast User Switching only works on Personal and Professional when joined to a workgroup. Thus, machines joined to a domain are not affected by this service.
If the service is stopped or disabled, the shims* used to make applications work in a multiple user environment will not occur. You will not have application compatibility for known Fast User Switching issues.
*Shims are application compatibility fixes which are used to address application compatibility issues reported to Microsoft.
