How to troubleshoot error 0x80070070

Windows Update needs working space for downloading, extracting, staging, rollback, and temporary files—not only the visible update size.

1

Check the Windows drive

Open Settings > System > Storage and confirm free space on the Windows drive. Also note whether the error identifies another partition.

2

Use supported cleanup tools

Review Temporary files or run Disk Cleanup. Remove only categories you recognize and preserve Downloads unless you have reviewed it.

3

Restart and retry the update

After creating adequate working space, restart Windows and check for updates again. Investigate partition-specific errors before resizing anything.

Before advanced repair: Do not manually delete Windows servicing folders or resize partitions until you know which volume is full and have a current backup.
