We’ll try to fix it the next time you sign in.” (may happen with or without Cortana) where your start menu eventually freezes, Cortana doesn’t respond to your typing, and Edge is not functional.

We have had this problem recently in one of our Windows 10 system despite this problem being so old. We have decided to summarize our findings to the problem in this post and show you the most effective fix after trying every possible solutions suggested on the internet.

Fix 1: Apply Windows Update

As we have mentioned this problem is old. It first happened during the very first month when Windows 10 releases few years ago. Microsoft already have the fix in the latest patches. All you have to do is turn on your Windows Update to receive the latest patches, especially if you own an old copy of Windows 10 and have previously turned off your Windows Update long time ago.

For some reason, we did turned off the Windows update (which is not recommended) for one of our working computers. The “start menu isn’t working” error eventually pops up and we solved it by re-enabling Windows Update.

Fix 3: Temporary boot into Safe mode and back to normal mode

This error has been around for few years without an actual fix for all victims. Some still suffer this despite having the latest patches applied from Windows Update. Until today, there are still many people reporting the same exact problem in Microsoft’s support forum even after applying all patches from Windows Update.

A representative from Microsoft has suggested to temporary boot your Windows 10 into safe mode and then back to normal mode. This may temporary get rid of the problem but eventually the start menu may crash and freeze again some time later. If the problem does come back, you will then have to do the workaround all over again.

To boot Windows 10 into safe mode:

  1. Hold and press Win Key + R to open Run window.
  2. Type msconfig and click OK.
  3. Go to Boot tab.
  4. Tick the “Safe boot” checkbox under boot options.start menu not working windows 10 msconfig safe boot
  5. Restart your computer. It will automatically boot into safe mode.
  6. When you are in safe mode, repeat step 1 to 3 to open msconfig.
  7. Under Boot tab, this time, uncheck the “Safe boot” checkbox.
  8. Restart your computer to boot into normal mode again.

Fix 3: Reinstall your antivirus software program

Some old antivirus software would interfere and cause Windows 10 interface to crash and freeze. If you are currently using an outdated antivirus software, update it to see if it solves the problem.

If it’s already updated (and if you have already tried all the solutions above but to no avail), try to uninstall your antivirus software and reinstall it. Some have reported that this solved theirs.
