Finally after 8 years of pause I tried to migrate Task Manager Extension to x64 (Vista and later).
Currently only Windows Vista is working fine with this release (both x64 and 32bit).
Windows XP is also better supported than before.
Windows 7 Task Manager currently crashes. Windows 8.1 Tasks Manager is not visible for extension.
Note! Support for Windows 95, 98, NT4, 2000 was dropped from this release!
