If you don’t have the InkFile registry value at all on your computer, then try some of the other methods below. Check to see if you can pin items to the taskbar now. Name the new string IsShortcut and don’t give it any value. In the right-hand pane, go ahead and right-click and then choose New – String Value (REG_SZ). Open the registry editor by going to Start and typing in regedit. Try to restart your computer and then try to pin a program to the taskbar. If you used a third-party program, then simply use that program to undo the removal. If you used a program to remove shortcut arrows on your desktop icons, then the first thing you should try is to restore those shortcut arrows.
Note, however, that there are some programs that cannot be pinned to the taskbar. If not, post a comment and I’ll try to help.
In this article, I’ll show you how to fix the problem, so you can again pin items to your Windows 7 taskbar! Hopefully, one of the methods will work for you. This can probably be caused by other reasons, but the fact is that there is a registry value called IsShortcut that somehow got accidentally deleted.
I figured something had gone wrong with the registry because I had tried to delete the overlay arrows on my desktop icons and fiddled with the registry. Unfortunately, something happened, or I did something wrong and this option disappeared! So I tried to drag the icon to the taskbar, thinking that would work, but it didn’t either! Instead I got a red round sign that meant I could not drop the item to the taskbar.
