Windows Update Not Enough Disk Space (Feature Update) Applies to: Windows 10, Windows 11

What it means

The feature update needs more free space than is currently available, even after normal Disk Cleanup.

Quick fix steps

  1. Free up at least 20-32GB of space — feature updates temporarily need much more room than regular updates.
  2. Use an external USB drive as temporary storage if internal space genuinely can't be freed — Windows Update can use it during install.
  3. Uninstall large unused apps or games temporarily, then reinstall after the update completes.

Frequently Asked Questions

Is this related to disk space specifically?
Yes, this is one of the most common causes — this error frequently relates to insufficient free space for the upgrade to complete, similar in spirit to 0x800f0922.
How much free space is actually needed?
Microsoft generally recommends at least 20-64GB free for a major feature upgrade, though the exact amount varies — checking Disk Cleanup and freeing up space liberally before retrying is the safest approach.
