The only issue I've had with stopping is when it decides to update, and just hangs there with a completion percentage and the message "This could take a while." I almost always end up holding down the power button because it'll sit on the same percentage, sometimes 100%, for hours.

I have a Windows virtual machine that was doing this to me a lot, and making Ubuntu reboots take a long time, and then requiring a disk check after the unclean shutdown.

I found a registry key that tells Windows to force stop apps that block shutdown. I may lose an unsaved document once in a while but I would have lost it anyway, and I am pretty good about saving things when necessary.

HKEY_CURRENT_USER\Control Panel\Desktop AutoEndTasks REG_SZ 1

My main complaint is all the programs that think all your documents are so precious that they refuse to shut down. Reminds me of

That vm I shut down last week, probably still is shutting down. Hope this answers your question

that happens to coincide with the 79 ways to "power off" windows.
