I saw different situations so fare.
One root cause was when a AV software blocks a file temporary during an update while it is scanning all involved files. This usually goes in hand with an installation process but it can fail if the system get blocked in his processes. I had seen this so far only two times with calibre during an update while calibre was running in back ground (my fault). The calibre program folder was blocked with system authority. You can normally solve this problem with canceling the installation and rebooting the system.
I have seen this behavior more often with Acrobat CC when you open and close PDF files fast and try to delete immediately the file. The file is then locked and when you delete the file some time later the folder of the file can't be deleted. You can delete the folder after a reboot.
There is also an other root cause when WINDOWS 10 makes security updates in background where the system waits for a reboot. Then it can also happen that your current user account lack on rights.
For this problems on my system an attribute change was not not a possible solution as these blocks was not a attribute problem it rather was a rights problem where user admin rights are not enough to clear a system lock for involved files and/or folder.
