We have some shared PCs, each user has their own login and profile. The PCs are used by shift workers and are used 24 hours a day. There are frequently over 100 profiles on these PCs. We find these PCs slow way down, and can take 1-30 minutes to log on. Is there any documentation on how many profiles and what sizes are recommended? Most answers I find say it doesn't matter, since rarely is more than one loaded at a time. I deleted 150 profiles (all but mine) from a PC and it went from the login prompt into fully functioning Windows in around 30 seconds. Prior to deleting the profiles it took over 1/2 hour, and sometimes just showed the spinning cursor for over an hour and the rebooted the PC. I'm in the process of cleaning the 4th in a few days, they all have 90 to 170 profiles and run fine once the profiles are cleaned out.
