Avoid making changes in the temporary profile to prevent data loss; 2. Rename the corrupted user folder (e.g., to username.bak) from another admin account and restart to let Windows create a new profile, then copy personal files (excluding AppData, NTUSER.DAT); 3. Fix registry issues by checking ProfileList keys for correct ProfileImagePath and healthy State/RefCount values, renaming the folder and deleting problematic keys if needed after backing up the registry; 4. Run sfc /scannow in Command Prompt as admin to repair corrupted system files; 5. Run chkdsk C: /f /r to fix disk errors, scheduling it at reboot if necessary; 6.

As a last resort, create a new user profile, copy data from the old folder, and delete the corrupted account after backup — your original files are typically still recoverable with careful steps, so the issue can usually be resolved without permanent loss.

If you're encountering a temporary profile login issue in Windows 10, it means Windows couldn't load your regular user profile and instead created a temporary one. This results in losing access to your files, settings, and apps. The good news is that your original profile is usually still intact — Windows just can't load it properly.

Here’s how to fix it:

1. Don’t Make Changes in the Temporary Profile

Before doing anything:

• Avoid saving files or making changes in the temporary profile.
• The changes won’t be saved to your real profile, and you risk losing data.

Instead, log out and try to access your account from another administrator account if possible.

2. Check for Corrupted User Profile

Windows often loads a temporary profile when it detects an issue with your user profile. Here’s how to fix it:

Step 1: Log in with Another Admin Account

• You’ll need access to a second administrator account.
• If you don’t have one, boot into Safe Mode with Command Prompt (via recovery options) to create one.

Step 2: Rename the Corrupted Profile Folder

• Press Win R, type C:\Users, and press Enter.
• Locate your user folder (e.g., C:\Users\John).
• Rename it to something like John.bak.

  This preserves your files and settings in case they’re needed.

Step 3: Restart and Log In Again

• After renaming, log back into your account using the original username.
• Windows will create a fresh profile.
• Then, manually copy your personal files (documents, pictures, etc.) from the .bak folder to the new profile.

?? Don’t copy AppData, NTUSER.DAT, or other hidden system files — they can carry the corruption.

3. Fix via Registry (Advanced)

Sometimes the issue is due to a registry misconfiguration pointing to the wrong profile.

Steps:

1. Press Win R, type regedit, and press Enter.

2. Navigate to:

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

3. Under ProfileList, look through the subkeys (like S-1-5-21...) for one that has:

   • Your username in the ProfileImagePath.
   • A value named State with data 0 (healthy).
   • Avoid keys with State = 4 or RefCount = 1 — these may be temporary.

4. If you find a key with:

   • Correct ProfileImagePath but no .bak suffix.
   • And it has a RefCount or State issue — rename the folder in C:\Users to .bak and delete the registry key.
   • Then reboot and log in again to rebuild the profile.

? Always back up the registry before making changes.

4. Run System File Checker (SFC)

Corrupted system files can prevent profile loading.

Open Command Prompt as Administrator:

sfc /scannow

Wait for the scan to complete. If issues are found, it will attempt to repair them.

Then restart and try logging in again.

5. Check Disk for Errors

File system errors can corrupt user profiles.

Run in Command Prompt (Admin):

chkdsk C: /f /r

You’ll be prompted to schedule the scan on next reboot. Type Y and restart.

6. Ensure Correct Permissions

Your user account must have full control over its profile folder.

• Right-click the C:\Users\YourName.bak folder → Properties → Security tab.
• Click Edit → Add → type your username → Check Full Control.
• Apply and propagate permissions to subfolders.

Then rename back to original name (if trying to reuse) or copy files safely.

7. Create a New User Profile (Last Resort)

If nothing works:

1. Create a new admin user via Settings > Accounts > Family & other users.
2. Log in to the new account.
3. Copy your personal data from the old profile folder.
4. Delete the corrupted account (after backup).

Bottom line: The temporary profile issue is usually fixable by renaming the user folder, repairing system files, or correcting registry entries. The key is acting carefully to avoid permanent data loss.

Basically, don’t panic — your files are likely still there.
