A fix is released to improve disk space requirements when trying to install the Windows 10 November update

We have recently addressed an issue that improves the ability to install the Windows 10 November update on systems with low available storage space.

Previously, on systems with small hard drives (16 GB or 32 GB), you may not have been able to free enough space to upgrade, even with the assistance of external storage.  In this scenario, Windows Update would report an error when trying to install the November update:  “We found some issues.  Select this message to fix and finish updating.”  When clicking the “Fix issues” button, a message would appear that said “Windows needs more space”, and one option provided is to “Choose another drive or attach an external drive...”  If you selected this option and attached the external drive, Windows was not making good use of that external storage, and you may have seen a message saying that you still needed a similar amount of free space to install the update.

With the fix that we’ve released (KB3124260), Windows will better use external storage, making it much more likely that the install will continue once you select to use an external drive and hit the Refresh button.  The fix reduces the amount of space required on the C: drive by over 2 GB. 

Please note that this issue and fix only apply to Windows 10 devices upgrading to the November update.  It does not apply to Windows 8.1 devices.

If you had previously experienced this issue, to get the fix you’ll first need to remove the temporary Windows installation files so that you can download them again, this time with the fix included.  To do this:

  1. Run Disk Cleanup.

  2. Click Clean up system files.

  3. Select Temporary Windows installation files and click OK.

Then check for Windows Updates and try reinstalling the Windows 10 November update.  When the update downloads, it will include the fix that will make it easier to use an external drive to install the update if you are low on free disk space.

Thank you.
