Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If you had a version of Microsoft Works then the task launcher would be installed along with the rest of the product. Works is no longer included with new PCs, and you may instead have the Office Starter edition (which is sometimes referred to as Works, but is a different animal entirely). Office Starter does not include a task launcher.
Frankly I don't see the point of such a beast, especially with Windows 7 which has its own task manager which runs across the bottom of the Window.
If you must have the Works task manager you will need to find a copy of Works Version 9, which is, I believe, now discontinued.
If you have kids using your PC, ensure that you setup separate Windows user log-ins for them to keep them out of your personal data.
