If creating a new profile resolves the issue, you will need to migrate your data and settings from the old profile to the new profile. This can be a time-consuming process, but it’s necessary to ensure that you don’t lose your important files and configurations.

* **How to migrate data:**
1. Open File Explorer.
2. Navigate to the old user profile folder (usually located in `C:\Users\OldUsername`).
3. Copy the contents of the old profile folder (e.g., Documents, Pictures, Downloads, Desktop) to the corresponding folders in the new user profile folder (usually located in `C:\Users\NewUsername`).
4. **Important:** Be careful not to copy the `ntuser.dat` file, as this file contains the user’s registry settings and can potentially corrupt the new profile if it’s copied from a corrupted profile. Consider copying only the essential folders and files first, then manually reconfiguring application settings.

### 10. Advanced Troubleshooting: Registry Editor (Caution Advised)

**Warning:** Modifying the registry can be risky and can potentially damage your system if done incorrectly. It’s recommended to back up your registry before making any changes. Only proceed with this step if you are comfortable working with the Registry Editor.

1. Open Registry Editor. To do this, search for “regedit” in the Start menu and click on the result.
2. Go to “File” -> “Export.”
3. Choose a location to save the backup file, give it a name, and click on “Save.”

* **Checking ProfileList in Registry Editor:**

1. Open Registry Editor (regedit).
2. Navigate to the following key: `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList`
3. Examine the subkeys under `ProfileList`. Each subkey represents a user profile.
4. Look for subkeys that have a `.bak` extension at the end. These are usually backup profiles created when Windows detects an issue with the original profile. If you find a key with a `.bak` extension *and* a corresponding key *without* the `.bak` extension, it might indicate a problem.
5. **Potential Fix (Proceed with Caution):**
* Delete the key *without* the `.bak` extension. This forces Windows to use the backup profile.
* Remove the `.bak` extension from the backup key. Rename it to the original profile name.
6. Restart your computer and try switching profiles again.

* **Double Profile Entries:**
Sometimes, duplicate entries in the `ProfileList` can cause conflicts. If you see multiple entries for the same user, delete the incorrect or outdated entry. **Be very careful to identify the correct entry to delete.** Check the `ProfileImagePath` value in each key to confirm which profile it points to.

### 11. In-Place Upgrade (Last Resort)

If none of the above solutions work, you can consider performing an in-place upgrade of Windows. This process reinstalls Windows while keeping your files and applications intact. However, it’s still recommended to back up your data before performing an in-place upgrade.

* **How to perform an in-place upgrade:**
1. Download the Windows Media Creation Tool from the Microsoft website.
2. Run the tool and choose “Upgrade this PC now.”
3. Follow the on-screen instructions to complete the in-place upgrade.
