General changes, improvements, and fixes for PC

• We fixed an issue resulting in some Insiders seeing error 0x8007023e when installing updates.

• Magnifier now remembers its window position after close and will reopen in that same location next time.

• We fixed an issue where, when capturing a repro video while filing a bug via Feedback Hub in Windows Mixed Reality, you couldn't select Stop video.
