Purpose: mstask.exe provides the ability under Win98/Me to schedule programs that will run at a specific time or repeatedly on a recurring basis. In Win98, Task Scheduler has an icon in the tray that you can click to see the list of scheduled tasks. In Windows Me, you access its user interface through Control Panel. If you disable Task Scheduler, it will not be possible to schedule tasks. Windows itself sometimes uses Task Scheduler for running programs, so disabling it is not advisable even though Windows will generally function fine without it.

mstask.exe is an essential part of Windows and required for Windows to work properly. It should never be disabled.
