Not enough disk space

Windows needs more free space on the drive used for the update.

TRY THIS FIRST

Check your free space

Open PowerShell and paste this command.

Read-only · No administrator access needed

PowerShell

Get-PSDrive -Name ($env:SystemDrive.TrimEnd(':')) | Select-Object Name, @{Name='FreeGB';Expression={[math]::Round($_.Free / 1GB, 1)}}

Result: FreeGB shows the space available on your Windows drive.

Still not working?

Open Settings → System → Storage and review cleanup recommendations. Remove only files you recognise and have backed up, then retry the update. Use the space requirement shown by Windows; there is no single minimum for every update.

Check the result: The same update finishes without the disk-space error.
