How to find user profile disk from registry

To locate the User Profile Disk (UPD) in the registry, you can follow these steps:

1. Open the Registry Editor:
   • Press Win + R to open the Run dialog, type regedit, and press Enter.
2. Navigate to the Profile List in the Registry:
   • Go to the following path:
     Copy code

     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

3. Locate the SID for the User:
   • Each user profile is associated with a unique Security Identifier (SID).
   • Under ProfileList, you’ll see folders named with long strings that start with S-1-5-.... These are the SIDs.
   • Click through each SID and check the ProfileImagePath entry to identify which SID corresponds to the user you’re looking for.
4. Check the Profile Path:
   • Once you’ve identified the correct SID, look at the ProfileImagePath value. This entry shows the file path to the user’s profile, which can also indicate the UPD location if it’s mapped to a specific disk or location.

If the profile is on a User Profile Disk, the path should include the location where the UPD is stored. In some environments, the UPD might be located on a network drive or a specific folder, often mapped under the C:\Users directory with the username.
