Maximum number of C:\User profiles allowed in Win 10 (not local accounts)

Question

My company has a dozen domain PCs at different sites with Windows 10 Pro being used to check-in visitors. Because many domain users log into these PCs over time a large number of profiles have been created in the C:\Users folder. In one case we had 65 profiles.

Does Microsoft have a Best Practice on the maximum number of DOMAIN user profiles (NOT local accounts) allowed in Windows 10 Pro before performance issues arise. And if the max is exceeded specifically what type of performance issues could occur?

Answer 1

We don't use guest accounts. These are receptionists who log onto the PCs with their own domain username/password. The first time they log onto a PC it creates a profile for them under C:\Users.

We can use Group Policy to delete these old profiles but I kinda want a benchmark on how many of these profiles Windows allows in C:\Users before performance issues set in.

Answer 2

Its easy to delete Profiles by GPO. I was hoping that someone might know a Best Practice on how many Profiles can reside in C:\Users before causing performance or other issues.
