How to Disable Disk Cleanup

Windows Disk Cleanup is a built-in tool to help reclaim disk space. Under certain circumstances, however, it can nag the user and become an irritation. This may happen when disk space is critically low, in which case the notification can be disabled. Alternatively, the system may be running the application automatically at scheduled intervals. In this case, the task can be deleted.

Disable the Low Disk Space warning (XP/Vista/Windows 7)

Step

Start the Registry Editor by clicking "Start," selecting "Run," typing “regedit” and pressing "Enter" if you are using Windows XP. If you are using Windows Vista or Windows 7, click "Start" and type "regedit" into the Search field. Press “Enter.”

Step

Find and select “HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer.”

Step

Create a new entry in this location. Click “Edit,” select “New” and choose “DWORD Value.” Type or copy and paste “NoLowDiskSpaceChecks” into the box and hit the “Enter” key. If this already exists, move to the next step.

Step

Make the new entry positive. Select it, click “Edit” and choose “Modify” or simply double-click it. Enter “1” and click “OK.”

Step

Quit the Registry Editor and restart your computer.

Delete Scheduled Task (XP)

Step

Open Scheduled Tasks by clicking "Start," selecting “All Programs," choosing "Accessories," clicking "System Tools" and selecting "Scheduled Tasks.”

Step

Find and select any entries in the list that refer to Disk Cleanup. Hold the “Ctrl” key while clicking to select multiple items.

Step

Click “Delete Item” and select “Delete the selected items” in the sidebar to the left.

Disable Scheduled Task (Vista/Windows 7)

Step

Click "Start" and type “Task Scheduler.” Hit “Enter.”

Step

Find any entries in the Active Tasks box at the bottom that refer to “Disk Cleanup” and double-click them.

Step

Click “Disable” in the sidebar on the right and close Task Scheduler.
