How to fix Windows 10 Critical error: Your start menu isn't working.

I wonder does everyone who has the Start Menu problem actually have dropbox installed as I do...

Did you install dropbox before or after Windows 10? Maybe that makes the difference.

I'm not even the OP of this thread, somehow my comment in another thread in response to a video saying how to fix the start menu by uninstalling dropbox got moved to a new thread of it's own. In my case, I have no idea if it's dropbox or not except I keep my system up 24x7x365 and only reboot when some software update requires it so it's about 3 weeks or so and each time, after rebooting, my HDDhealth.exe will say it cannot write to C:\Program Files (x86)\HDDHealth\_identity.bin repetively on windows login and that's when the start menu stops working. It always happens a little less than 30 days after a install on September 12, 2015 and October 13, 2015 and October 26, 2015.

It's not a conflict, it seems to be a Windows 10 permissions issue which is what the dropbox issue is too from what I read. HDDHealth.exe uses SMART built-into HDD/SSD's to monitor their health on a real time basis. The only thing is that file never gets modified or written other than when it was first installed as the last modification date is always the installation date as the copies it changes is in C:\Windows. I was commenting as I already fixed the problem with a in-place upgrade each time, it's faster than trying the other methods.

O.k. is a bit confusing as you are at the beginning even tho i do not see you as thread starter and you said it was moved by Admin.
Just seemed as though start menu issues has happened from these other files.

I basically read all the forums here once a day and today, I noticed the topic and I was the threadstarter and there was a reply so I responded to it. Mines always says Start Menu has a critical error, never mentions Cortana like everyone else says even though my Cortana doesn't work either when it happens. In any case, the first time I saw mention of dropbox which was a week ago, I uninstalled and reinstalled it just to see if it is really the culprit.
