StartAllBack is a fan-favorite app among power users. It allows users to address the shortcomings of Windows 11's native Start menu and change it to the way they like it. But if you have the app installed, it turns out that Microsoft is going to create trouble for you.

With StartAllBack installed on your system, you won't be able to install the latest Windows 11 updates on your PC. Windows is citing security and performance issues while blocking the StartAllBack app. It shouldn't be too surprising for users, since StartAllBack uses a Windows shell hack to provide the features that it does. And as Microsoft is refactoring the shell experience in Windows 11, it seems like the source of the block.

While all the logic does make sense, it doesn't mean that it leaves users happy. They just wanted some old Windows functionality back, like being able to move the taskbar to the left/ right, and the app is the only way to get it. But there's no reason to be too unhappy. While it includes an extra step, it's all too easy to update your Windows 11 PC.

To solve this problem, first, you need to uninstall the StartAllBack from your PC.

Then, go to Settings > Windows Update and install the latest updates on your PC.

Now, you can reinstall the StartAllBack. However, there's a caveat. You can't normally install StartAllBack anymore, since Windows is blocking the app. But all you need to do is rename the executable (exe) file for StartAllBack so it doesn't include the name 'StartAllBack' in it. After that, you will be able to install the app just fine.

If you think all this is too much hassle, there's also another popular app, Start11, that lets you customize your Start menu in Windows 11. It doesn't provide the same options as StartAllBack, but you won't face any update issues with this app installed.
