Here’s a quick tip on how to backup all the items that you have pinned in your taskbar.
Just access the path below. Replace the ‘User’ with your username:
C:UsersUserAppDataRoamingMicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar
If you don’t know your username. Then just click on the start button and check out the name indicated just above the Documents shortcut. The one that I highlighted.
Now you will find all the shortcuts. Just back them up using good old ctrl + c and ctrl + v. Into a safer location.
So that everytime the shortcut is accidentally deleted. You can just copy from your backup, then paste into that location.
