0x8007001E
Microsoft Windows Update
Severity: ModerateWhat Does This Error Mean?
Windows Update error 0x8007001E means Windows ran out of storage space while trying to download or apply an update. The error code translates to 'Not enough storage is available to complete this operation.' Windows needs free disk space not just for the update files themselves, but also for temporary files during the installation process.
Affected Models
- Windows 10
- Windows 11
- Windows Server editions
Common Causes
- The system drive (usually C:) does not have enough free space for the update
- The Windows Update temporary folder (SoftwareDistribution) has grown very large
- There is not enough virtual memory or page file space available
- Low RAM combined with low disk space is causing insufficient working memory
- The Windows component store has become corrupted, wasting disk space
How to Fix It
-
Check your available disk space: open File Explorer, right-click the C: drive, and select Properties. You need at least 10–20 GB free for Windows updates.
Windows Feature Updates (major versions) require 20+ GB of free space. Security updates need less but still require a few GB.
-
Run Disk Cleanup: type 'Disk Cleanup' in the Start menu search bar, select your C: drive, click 'Clean up system files', and check everything you can safely delete.
Previous Windows installations (Windows.old), temporary files, and delivery optimization files can free up significant space.
-
Clear the Windows Update cache: open Services (search 'services' in Start menu), stop the 'Windows Update' service. Then delete all files in C:\Windows\SoftwareDistribution\Download\. Restart the Windows Update service.
This folder stores downloaded update files. Clearing it forces Windows to re-download updates fresh.
-
Run the Windows Update Troubleshooter: go to Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run.
This tool automatically detects and fixes common Windows Update issues including storage-related errors.
-
Run System File Checker to repair any corrupted system files: open Command Prompt as Administrator and run: sfc /scannow
Follow with: DISM /Online /Cleanup-Image /RestoreHealth — this repairs the Windows image and can free up space used by corrupted components.
When to Call a Professional
If cleaning disk space and the SoftwareDistribution folder does not resolve 0x8007001E, and you are low on RAM, contact a computer technician to assess whether a hardware upgrade is needed. Adding RAM or upgrading to a larger SSD are the permanent solutions to chronic storage and memory errors.
Frequently Asked Questions
How much free disk space do I need for Windows updates?
For regular security and quality updates, have at least 5–10 GB free. For major feature updates (like Windows 10 to 11 upgrades), you need at least 20 GB free. Windows will warn you before large updates if space is insufficient.
What is the SoftwareDistribution folder and is it safe to delete?
The SoftwareDistribution folder is where Windows temporarily stores downloaded update files. Stopping the Windows Update service first, then deleting the contents (not the folder itself) is safe. Windows will re-download whatever it needs next time updates run.
Can I install Windows updates on an external drive to save space?
No — Windows updates must install on the system drive (usually C:). However, you can move your Documents, Downloads, and other personal files to an external drive to free up space on C: for updates.
