How to Resolve Critical Issues with the Windows 10 Start Menu

When you initially encounter the issue of the Windows 10 Start button not functioning due to a critical error message, don't hesitate to refresh your computer one or two times, or simply shut it down and restart. This is the safest and quickest method to assess the severity of the problem you're facing.

But many people aren’t so lucky to fix the critical error with Start menu and Cortana so easily. Next, we have some general troubleshooting for you to try.

Solution 1: Install the Latest Windows 10 Update

Since the critical error prevents you from accessing the Settings option in the Start menu, let's bypass the Start menu and get to the location where the update can be found.

Step 1. Press the Windows + R keys on your keyboard simultaneously to open the Run dialog box. Type ms-settings: in the empty field and then press Enter.

Step 2. On the Settings panel, click Update & security and then Check for updates. If you're running Windows 10 version 1511, you should go to System > About > Version. Follow the prompts to install the latest update available on your PC.

Solution 2: Download the Start Menu Troubleshooter

You should be aware that issues with the Start menu are common with each Windows 10 update, so you're not alone in experiencing this problem.

Solution 3: Boot into Safe Mode and Then Return to Normal Mode

It appears that booting into Safe Mode is the most effective solution, as numerous users have reported that entering Safe Mode, and then returning to Normal Mode, resolves the critical error. However, some have mentioned that this is only a temporary fix, as the error reappeared after a certain period. Nonetheless, it's worth attempting.

Step 1. When Windows 10 boots up, press the Windows Key + L to log out of your account.
Step 2. Click on the "Power" icon located in the bottom right corner of the screen, then while holding down the "Shift" key on your keyboard, click "Restart".
Step 3. Your computer should now reboot into the Boot Options menu. Navigate to "Troubleshoot" > "Advanced options" > "Startup Settings". Click the "Restart" button to proceed.
Step 4. After your computer restarts, press F5 to enter "Safe Mode" with Networking enabled.
Step 5. Once in Safe Mode, your issue should be resolved. Simply restart your computer normally to continue using it.

Aside from the three general methods for Start menu troubleshooting, keep in mind your antivirus software. It's been reported that third-party antivirus programs can silently cause critical errors with the Start menu. Try to uninstall it, and then reinstall it to see if that resolves the issue.

Moreover, there are a few insights from experienced users who have resolved their issues. The subsequent sections might be slightly more advanced, so it's crucial to exhibit patience and diligently follow the comprehensive guide.
