This registry workshop will help you to fix 'Server execution failed' error for File Explorer (explorer.exe) in Windows 10. Also check the HotFix inside.

By default, File Explorer in Windows operating systems (OSes) shares same explorer.exe process for all Explorer windows. This means if you open Desktop, Taskbar and few File Explorer windows, they all will be sharing a common process, named explorer.exe. Hence, when you press End Task button for this same process in Task Manager, you’ll find that Desktop and Taskbar is also restarted along with File Explorer.

However, sometimes the third-party software you use on your Windows may change the above mentioned default behavior, and may allow the OS to launch folder windows as a separate process. If this happens, Desktop and Taskbar will get isolated explorer.exe process separated from File Explorer‘s explorer.exe process. The new instances of File Explorer launched will have other brand-new explorer.exe processes. Hence, now if you restart Explorer windows, Desktop and Taskbar won’t be reloaded and they keep running.

Recently, we came around an issue in Windows 10 which is supposed to occur if OS is launching folder windows as separate process. The error is:

Server execution failed.
