Classic Shell 4.3.0 is officially supported on Windows 10 Anniversary Update.
Classic Shell 4.3.1 is officially supported on Windows 10 Creators Update.
Classic Shell 4.3.1 is reported by the majority to run on Windows 10 Fall Creators Update, but some others are reporting various issues.
It mostly works well on a clean install.....until the next Windows update/upgrade comes along to disrupt everything. As you may or may not be knowing, Classic Shell is no longer the priority for the developer (Ivo), nor for me (I was one of the testers). Windows 10 has caused me to lose interest in the PC platform completely.
Classic Shell is in maintenance mode. New features and new releases will be very slow or unlikely. Issues with Windows 10 might be because of no testing performed by me on that OS. Even if you find issues, they must be reliably and consistently reproducible, only then can Ivo fix them. And that's the problem with Windows 10 - it gives everyone a very inconsistent experience.
The community is of course free to carry the Classic Shell project forward and there are other decent Start menu solutions too.
Because of the way Windows 10 is serviced and updated, it routinely creates crashing issues for Explorer because Microsoft's upgrade process is imperfect even after years of trying and cannot even properly migrate desktop app settings after the upgrade - it ends up deleting or corrupting certain configuration in the Registry required for Win32 programs to work properly. On a clean install of Windows 10's latest release, Classic Shell works. But often when in-place upgrades are done, Windows Setup damages it or causes serious issues due to their imperfect update process causing a partially installed state where Classic Shell crashes Explorer. I recommend you to stay with Windows 7 or 8.1 if you want to use Classic Shell.
You could capture a crash dump as per these instructions:
viewtopic.php?f=12&t=6 but there are so many instability issues in general with Windows 10 that it is always going to give you problems. It's not a good, well-engineered, well-tested system.
Another thing you can try is download the Classic Shell Utility from here:
http://www.mediafire.com/download/3uker ... tility.exe and use it to clean all traces of Classic Shell from your existing installation, including all settings. Then try a clean install of the newest version.
However we cannot guarantee it won't crash or break again because Microsoft designed Windows 10 to routinely break desktop apps that integrate deeply with the system.
At present, there is an issue with Explorer hanging/freezing and crashing reported by a small group of users on Windows 10. The handle and thread count of Explorer process increases when the Start Menu is running.
If you are doing an in-place build upgrade (not a clean install) and Windows removed Classic Shell for you, the fix that will most likely work is using the Utility to remove all traces of it including all settings for all users and then reinstall it.
However, Windows 10 Setup also sometimes causes messed up Registry and file system permissions during the upgrade, causing Classic Shell to not work. Sometimes, the MSI installation data gets damaged or improperly migrated during the Windows 10 update. Some others have reported that changing the installation path from the default is causing it to crash. It is clear that Microsoft does not want non-Store desktop apps to survive for long.Also, on some PCs which have IDT audio hardware, the audio driver (IDTNC64.cpl file to be specific) is known to be incompatible with the latest Windows 10. It can cause Explorer/Classic Shell to crash. Uninstall IDT audio driver or get the updated fixed one from HP's website for your PC model.
Besides IDT, there is one more driver that has been reported to cause Explorer/Control Panel/Classic Start Menu crashes - Realtek's audio driver if you haven't updated it, contains RtkAPO.dll/RltkAPO64.dll which has the same effect as IDT's CPL file.
The real "fix" is to not use Windows 10 at all since it is a very problematic OS that fails all quality control standards and never stops harassing the user via bloated forced updates. If you use it anyway, there is no incentive left for Microsoft to fix anything since they already have your support. They will continue to take you for granted and drop the ball on Windows quality even more. All Windows feedback falls on deaf ears and critical bugs and design flaws in the OS are never fixed as you may be knowing from experience.
Use Windows 8.1 with Classic Shell if you want a more modern OS than Windows 7 without the hassles of Windows 10. You will be surprised at how well Windows 8.1 works once Classic Shell is installed to suppress the Metro UI.
