How to Fix C Drive Out of Space Issue on Intune Managed Windows Devices ! There is an issue on Windows devices managed through Intune where the C: drive (250 GB HDD) frequently runs out of available space. This problem is occurring across multiple systems, impacting performance and daily operations.
After performing the disk cleanup or using other storage management tools, the available space on the C: drive does not remain consistent. Devices show a temporary increase in free space, but it soon decreases again without any significant user activity or large file downloads.
The fluctuation in C: drive space occurs because certain background processes and system activities automatically consume storage after cleanup. Windows creates temporary files, update caches, and diagnostic logs during regular operations.
These files can accumulate quickly, reducing the available disk space even after running cleanup tools. Additionally, devices managed through Intune may generate management or diagnostic logs that contribute to this issue. As a result, the available storage keeps increasing and decreasing frequently, causing noticeable fluctuations on the C: drive.

Workaround for C: Drive Filling Issue on Intune-Managed Windows Devices
Windows devices managed through Intune may experience C: drive space consumption due to excessive log and temporary file generation, particularly in the C:\Windows\Temp\WinGet\defaultState folder. This can make devices nearly unusable if not addressed promptly.
| Workaround for C: Drive Filling Issue | Details |
|---|---|
| Stop the Intune Management Extension Service | You can open services.msc and locate Microsoft Intune Management Extension, right-click, and select Stop. This prevents files from being in use while deleting them. |
| Delete the problem files | You can navigate to C:\Windows\Temp and C:\Windows\Temp\WinGet\defaultState, and delete all contents inside these folders. Do not delete the folders themselves. |
| Restart the Intune Management Extension Service | Return to services.msc, right-click the service, and select Start. |
| Restart the device | Rebooting ensures all changes take effect and frees up disk space. |
| Optional Automation | For ongoing mitigation, deploy PowerShell detection and remediation scripts via Intune. The detection script checks if the folder exceeds 2GB, and the remediation script clears its contents automatically, reducing the need for manual intervention. |
