Windows 10 Start & Cortana critical error issue?
« on: August 06, 2015, 01:15:54 PM »
This was reported by a user on Windows Central. "Do those dealing with this problem have avast antivirus installed? If so, I believe that is what is causing the 'critical error'. I uninstalled the software and upon reboot my start button and cortana were working perfectly again."
If this is correct then Avast will need updates soon. If not an Avast issue then Windows Central need to be informed.

Repair Avast:
1. Control Panel -> Add/Remove programs -> Avast
2. Click on 'Repair'.
3. Follow instructions.
4. Reboot.

I'm having this problem as well, start and some task bar icons don't work.

Windows defender is greyed out.

Also can't find avast in control panel/programs to carry out a repair or uninstall n re-install.

Also Avast updates are hanging. I've also sent 2 notices via the app regarding this issue with no response

I had this problem and also, even if I don't get the critical error, the whole Windows 10 UI freezes. I have to use the task manager to restart the explorer.exe and than bang!! Same thing happens... Sometimes I get the Start & Cortana Critical Error if I wait long enough.

I had to switch to another antivirus because of this.

It is not avast related on. Just had this one from nowhere first time on Windows 10 after one month. Just restarted my PC once and error is gone.

Fighting this issue for 3 days now (and I'm an experienced break/fix tech)

You can try system restore, but in order to do that your going to have to completely uninstall avast! and reboot first (make sure you reboot). For whatever reason, even with the SDM turned off, system restore isn't able to modify the definitions folder for avast! and will fail.

My first system restore has brought back Cortana, but I still don't have a start menu.

As far a rebooting to fix..... I'm sorry to say that you are only at the beginning of the problem my friend. It started out like that for me too. Reboot/Logout would fix it every time. Then, a few days later..... start & cortana are both completely unresponsive.

When I figure it out, I'll post

Sadly, but It's true. Still it's a fact! I'll wait some resolution of this matter.

I had to reboot my system several times to get this cleared up.
Sorry, I don't buy into the thinking it's an avast issue. I do believe in
making regular system backups. At least twice a month preferably once a week.
An aggressive backup program is a must. There are several backup utilities available,
personally I use AOMEI Backupper Free. To be honest I'm making a backup right now.
