If the 'Max Usage' setting in 'System Protection' keeps reverting from 5% back to 50% even after changing it, there are a few possible reasons and solutions to consider:

Possible Causes and Solutions:​

1. Permission Issues:
   • Cause: Limited user permissions might prevent the system from saving the changes.
   • Solution: Make sure you are logged in with administrative privileges. Right-click on System Protection, then select "Run as administrator" before changing the settings.
   []Group Policy Setting:
   • Cause: Group Policy settings might be overriding your changes.
   • Solution: Check Group Policy settings to ensure that there are no conflicting policies affecting System Protection. You may need to adjust Group Policy settings accordingly.
   []Corrupted System Files:
   • Cause: Corrupted system files could interfere with the changes being saved.
   • Solution: Run the System File Checker tool to scan and repair any corrupted system files. In an elevated Command Prompt, run:

     batch sfc /scannow

   []Third-Party Software Interference:
   • Cause: Third-party software or security tools might be reverting the setting.
   • Solution: Temporarily disable any third-party antivirus or system optimization software that could be causing conflicts.
   []Registry Settings:
   • Cause: Incorrect registry settings may prevent changes from being saved.
   • Solution: Manually check the registry setting related to 'Max Usage'. To do this, open the Registry Editor (regedit) and navigate to:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SR\Settings

     Verify and update the 'DiskPercent' value to 5%.
2. System Restore Point Limit:
   • Cause: Windows might enforce a minimum limit for System Restore points.
   • Solution: Check if Windows has a minimum threshold for System Restore point allocation. If so, you may need to allocate the minimum necessary instead of setting it too low. By addressing these potential causes, you can troubleshoot why the 'Max Usage' setting isn't saving at 5% and implement the appropriate solution to ensure that your desired setting persists.
