Thanks for posting and a big welcome to the Community
Sorry to hear that you've lost your saved shortcuts on your task bar. What version of Windows are you using please? I've had a bit of a play about with the PC I'm using which is Windows 7 and I can just drag and drop programmes and shortcuts to my task bar. Let me know what operating system you're using and I'll try and find specific instructions for you.

If you're using Windows 10: just drag stuff on to the taskbar, or if stuff is in the start menu right click on what it is you want, then select pin to taskbar. You can also access taskbar settings by right clicking on the taskbar itself, then a context menu will pop up. Select taskbar settings. Looks like Mickeysoft has kept this feature (not a bug!)
