I am working on a installer, it should check FUS (Fast user switching) is enabled or not on the XP system. If FUS is enabled then installer should exit, otherwise perform the actual installation. My question is there any command line utility (or API) to check if FUS is enabled on XP?
Thanks..
The vast majority of your users (assuming an average target market) will have Fast User Switching enabled, and will not know how to disable it and possibly not want to either. By doing this, you will annoy your customers and eliminate a large potential target market.
Why do you want to do this in the first place?
To do it, check the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AllowMultipleTSSessions.If FUS is enabled, it will equal 1.
