Hi John,

You may be able to temporarily resolve the issue by booting to Safe Mode, and then immediately booting back into normal mode. This workaround may resolve your problem for a while, however the error may return later.
To boot to Safe Mode:

• Hold the Shift key down while you click Start, Power, Restart.
• Once you are in the Windows Recovery Environment, select Troubleshoot, then Advanced options, then Startup Settings, and Restart.
• When it restarts, you should see a number of options. Press 5 or F5 for Safe Mode with networking.
• Once you sign into your account in Safe Mode, you’re done. Just restart your PC to return to a normal boot.

If you are running a third-party antivirus software, we recommend uninstalling, then reinstalling the antivirus software, as this may also provide a work-around for this problem. Some customers have reported that adding a new local administrator account has resolved their Critical Error. If that doesn’t work, try removing the original administrator account now that you have a new one created.

Here’s how to create a new local account:

• Click Start, Settings, Family & other users, Add someone else to this PC. (Note that you can’t “Add a family member” with a local account. Presumably that is tied in to parental controls.)
• In the box marked “How will this person sign in?” down at the bottom, click “The person I want to add doesn’t have an email address.”
• In the “Let’s create your account” dialog, at the bottom, click “Add a user without a Microsoft account.”
• At that point, finally, you can type in a user name, password and password hint. Click Next and you suddenly have a local account ready to use on your machine.

Your programs don’t appear on the Start menu’s All Apps list
If you have more than 512 programs on your machine, Windows 10 gives up—the apps don’t appear on your Start all apps list. Although the apps are still installed, you can’t get to them through the Start menu. Your system may freeze, it may become very lethargic, and links might not work.
The 512 limit applies not only to programs. It’s the total of all the programs, folders, files, and shortcuts that you have in your Start menu, on the left and right (tiled) sides.
So, remove some programs.

I hope this helps.
