Back in the "Good ol' days" there was the Black Viper website, where you could get a detailed list of Windows Services, and a recommendation of which ones that could be either Disabled completely or just set to Manual Start.
The "Black Viper" is no longer running Windows at all, and has stopped his Services recommendations. ( sniff )
I used his info to write a Batch file to either disable or set to Manual Start, several Services that I would never want to have running as Automatic.
SysMain is one service that I gladly Disabled, since it runs 'Prefetch' which I don't want running, EVER.
I still run that Batch File on every Windows Install.
Windows will continue to RUN, even with all Services in their Default condition, but it's kind'a fun to disable those that will never be needed.
Cheers Mates!
