Progress installing the Windows 10 November update stops responding at 44%
We’ve observed that some devices that have an SD bus with an SD card inserted while installing the Windows 10 November update will stop responding at 44%, and we are currently investigating the issue.
If your install is freezing at 44%, check if you have an SD card inserted and remove it, and the update should be able to progress beyond this spot. If you needed the SD card for additional disk space, see if you have a USB/Mini-USB port available that you can use instead for the upgrade. Otherwise, you may have to try freeing up some disk space off the hard drive.
If you're hanging at some percentage other than 44%, please create a new post.
