When we try to open a photo, video, or app on a Windows PC and suddenly see an “Invalid Value for Registry” error, it’s usually caused by a glitch in the system registry. This error often occurs when a system update is incomplete, an app becomes corrupted, or a registry entry is incorrectly modified.
In this detailed guide, we’re sharing all the effective ways to permanently fix the ‘Invalid Value for Registry’ error in Windows.
What is the ‘Invalid Value for Registry’ error?
The Registry is the Windows database where all important system and application settings are stored. When an entry is incorrect, corrupted, or mismatched, the system can’t read the correct value, resulting in this error.
This issue typically occurs in the following situations:
- After a Windows Update
- When opening the Photos or Media Viewer app
- After changing the default app
- After making a manual change to the registry
Method 1: Reset the Windows Photos App
If this error occurs when opening Photos, the first step is to reset the Photos app.
Steps:
1. Open the Start Menu and click Settings.
2. Go to Apps → Installed Apps.
3. Find Microsoft Photos.
4. Click the three dots → Select Advanced Options.
5. Scroll down and click Reset.
Restart the system after resetting. This fixes the problem in most cases.
Method 2: Delete old entries using the Registry Editor
Be sure to take a registry backup before this procedure.
How to take a backup:
1. Press Windows + R
2. Type `regedit` and press Enter
3. File → Export
4. Save the backup file
Now to fix the problem:
1. Open the Registry Editor
2. Navigate to the following path:
HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Packages
3. Look for entries showing an old version number.
4. Delete any duplicate or outdated entries.
Restart the system and check again.
Method 3: Run the System File Checker (SFC Scan)
If registry files are corrupt, an SFC scan is very effective.
Steps:
1. Click Start
2. Search for “Command Prompt”
3. Select Run as Administrator
4. Type the command below:
sfc /scannow
5. Press Enter and let the process complete.
This tool scans for and automatically repairs all corrupt system files.
Method 4: Use the DISM Tool
If SFC doesn’t resolve the issue, run the DISM command.
Type the following command in Command Prompt (Admin):
DISM /Online /Cleanup-Image /RestoreHealth
This repairs the Windows image and helps fix registry value errors.
Method 5: Reset Default Apps
Sometimes this error occurs due to incorrectly set default apps.
Steps:
1. Settings → Apps → Default Apps
2. Scroll down and click Reset to Microsoft Recommended Defaults
This will restore the default values for all file types.
Method 6: Complete Windows Update
Incomplete updates also cause Registry conflicts.
1. Open Settings
2. Go to Windows Update
3. Install Pending Updates
4. Restart the system
Method 7: Check by performing a Clean Boot
If a third-party app is causing the problem, perform a Clean Boot.
Steps:
1. Press Windows + R
2. Type `msconfig`
3. Go to the Services tab
4. Tick Hide All Microsoft Services
5. Click Disable All
6. Open the Startup tab → Task Manager
7. Disable all Startup Apps
Restart the system.
Method 8: Create a New User Account
Sometimes this error occurs due to a corrupt user profile.
To create a new account:
1. Settings → Accounts
2. Family & Other Users
3. Add Account
4. Create a New Local User
Log in to the new account and check for the problem.
Method 9: Use System Restore
If the problem started recently, perform a System Restore.
1. Search for Start → “Create a Restore Point.”
2. Click System Restore
3. Select an earlier date
4. Start the restore
Advanced Solution: Reinstall the Photos App from PowerShell
If the Photos App is completely corrupt, reinstall it.
Run this command in PowerShell (Admin):
get-appxpackage Microsoft.Windows.Photos | remove-appxpackage
Then reinstall the Photos App from the Microsoft Store.
