Yes, it is possible to create multiple user profiles in the registry. The process is very straightforward and all it requires is the use of a few simple steps.
First, you need to start the registry editor on your system by searching for “regedit” from the start menu or running the regedit command from the command prompt. This will bring up the registry editor window.
Second, you need to navigate to the following location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. This is where all of the existing user profiles are stored and it is also where you will create the new profiles.
Third, you will need to create a new key for each user profile. To do this, you simply need to right-click on the ProfileList key, select New, and then Key. You’ll then be asked to name the new key (e.g. User1, User2, etc.)
Fourth, you need to specify the profile path for each user profile. To do this, double click on the newly created key and then navigate to the ProfileImagePath value under the Data column. In that value you should enter the path of the user profile.
Finally, you need to ensure that the permissions for each user profile are set correctly. To do this, right-click on the newly created key and select Permissions. Then grant the appropriate permissions for each user profile.
Once you have completed all these steps, you should have successfully created multiple user profiles in the registry.
