How to Check Reserved Storage in Windows 11

Understanding how much storage Windows 11 reserves for system updates and essential functions can help you manage your disk space more effectively. Reserved Storage is a feature that allocates a portion of your drive to ensure smooth updates, security, and performance. Sometimes, this reserved space can seem unexpectedly large, leaving less room for your files and applications. Checking the amount of Reserved Storage on your Windows 11 device allows you to monitor your disk usage and decide if adjustments are necessary. Before starting, ensure your device is connected to the internet and you have administrator privileges, as some steps require administrative access.

What You’ll Need

• A Windows 11 device with internet connection
• Administrator access to your device

Step-by-Step

1. Open the Settings app by clicking on the Start menu and selecting the gear icon, or press Windows + I on your keyboard.
2. Navigate to the System section in the Settings menu.
3. Scroll down and click on Storage from the list of options.
4. Within the Storage settings, look for the link labeled “Show more categories” or directly for “Reserved Storage”. If you don’t see it, proceed to the next step to check via Command Prompt.
5. If available, click on “Reserved Storage” to view the current reserved space. Windows will display the amount of storage reserved for system updates and related processes.
6. If you do not see this option, or want a more detailed view, open Command Prompt with administrator privileges by right-clicking the Start button and selecting “Windows Terminal (Admin)” or “Command Prompt (Admin)”.
7. Type the following command and press Enter:

   DISM /Online /Get-ReservedStorageState

8. The output will display whether Reserved Storage is enabled and the amount of space allocated.
9. For a detailed breakdown of disk usage, you can also run PowerShell commands such as:

   Get-ReservedStorage

   (if available) or check your disk usage via the Task Manager or third-party tools.

10. To modify or disable Reserved Storage, you’ll need to use the Registry Editor or Group Policy Editor, which is more advanced. Proceed with caution and back up your system before making changes.

Common Mistakes

• Confusing Reserved Storage with overall disk space; reserved space is a subset, not the total disk capacity.
• Attempting to disable Reserved Storage without understanding its impact on system updates and security.
• Not running Command Prompt or PowerShell as administrator, which can prevent commands from executing properly.
• Ignoring the need to back up your system before editing registry settings or making advanced changes.

Tips

• Regularly check your disk usage to prevent unexpected low storage issues.
• Use built-in tools like Storage Sense to automatically manage disk space.
• If Reserved Storage seems excessive, consider freeing up space by deleting unnecessary files or uninstalling unused apps.
• Keep your Windows 11 updated, as updates may optimize how Reserved Storage is allocated.
• For advanced users, consider adjusting Reserved Storage settings via Group Policy if applicable.

Troubleshooting

If you encounter issues when checking or modifying Reserved Storage, try these solutions:

• Command not recognized: Ensure you are running Command Prompt or PowerShell with administrator privileges.
• Reserved Storage not visible in Settings: Update Windows to the latest version, as newer builds improve visibility and control over storage management.
• Disabling Reserved Storage causes system issues: Re-enable it via Group Policy or Registry Editor, or restore your system from a backup.
• Low disk space persists despite freeing up space: Check for hidden files or system restore points that may occupy space.

If problems continue, consider reaching out to Microsoft Support or a professional technician for assistance.
