If the Windows 10 start menu stops working, it can grind your computer to a halt. This appears to be a fairly common glitch following a recent Windows 10 update. We've heard from a number of members who've reported problems with the Windows 10 start menu not working properly.
The good news is Microsoft is aware of the issue and has created a fix.
How to fix the Windows 10 Start menu
To download Microsoft's free Start Menu troubleshooter tool, copy and paste the following link into a new web browser tab, then press Enter: aka.ms/diag_StartMenu
When prompted, save the startmenu.diagcab file to your desktop (or somewhere that’s easy to find). Alternatively, it will show in your web browser under your downloads.
Once it has finished downloading, double-click the file to run it, then click Next and follow any remaining instructions until you’re prompted to close the Start menu troubleshooter tool.
Install Classic Shell
Classic Shell became hugely popular when Windows 8 was launched. It restores a Windows 7-style Start menu to your system. It's free, quick to install and runs without any further effort in the background, and can also provide a fix if you're struggling with the Windows 10 start menu.
You'll lose access to Cortana by installing Classic Shell, so this may not be the best long-term solution if you want to make the most of Windows 10. But if the Windows 10 Start menu issue is costing you the use of your PC, we'd recommend installing Classic Shell as a simple short-term solution until Microsoft rolls out a proper fix.
Head to the Classic Shell website and click Download Now. There are lots of options for customising the new Start menu, but you can easily leave these alone and stick to the automatic installation settings (or adjust them later).
