1. Press Windows + S, search “Disk Cleanup”
2. Select drive “C:”
3. Click “Clean up system files”
4. Check “Windows Update Cleanup” and “Temporary files”, then confirm This removes leftover update files that normal cleanup does not remove.

Error code 0x80070070 in Windows 10 indicates that the disk is full and there isn’t enough free space to download or install updates or an upgrade.

To fix it on Windows 10:

1. Check free space on the system drive
   1. Open File Explorer.
   2. Right-click Local Disk (C:) → Properties.
   3. Confirm there is sufficient free space. For Windows updates and upgrades, aim for at least 20 GB of free space on the OS disk.
2. Free up space Use any combination of these steps on the C: drive (or the drive where Windows is installed):
   • Uninstall unused apps and programs.
   • Delete or archive large files (videos, ISOs, old downloads) you don’t need.
   • Move personal files (documents, pictures, videos) to another internal drive, external drive, or another computer/cloud storage.
3. If still low on space
   • On a physical PC: use an external drive during the update/upgrade process. See “Updating Windows using an external storage device” for detailed steps.
   • On a virtual machine: extend the OS disk and then retry the update.
4. Retry the update or upgrade
   • Run Windows Update again, or rerun the Windows 10 upgrade.
   • For upgrade-specific errors like 0x80070070 – 0x50011, 0x80070070 – 0x50012, or 0x80070070 – 0x60000, freeing disk space and retrying the upgrade is the prescribed fix.

If the error persists after freeing sufficient space, collect Windows servicing and update logs as described in the Windows servicing troubleshooting guidance and contact Microsoft Support.
