+/*
+Allows to run explorer.exe in taskbar mode from any location. This can be used to run another version of Explorer
+without replacing system files. The path to explorer.exe can be specified in the registry key
+HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell.
+For running taskbar in Windows 10 mode, the localization folder should be available
+at the location of explorer.exe. For Windows 11 taskbar mode, this is not required.
+
+The mod makes explorer.exe think that it has been launched from %Systemroot%\Windows.
