Windows 10: Fixing Gaps in the Taskbar

August 27, 2018 by Michael

I make pretty extensive use of pinning icons to my taskbar.  After shuffling a few of them around and deleting ones I no longer use, I ended up with blank space where icons once where.

Here is an example of the problem:

In order to fix this problem I had to open regedit and delete the following two values from the TrayNotify key:

HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\IconStreams
HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\PromotedIconCache

Once those two keys are deleted you can either reboot your computer or simply terminate the explorer task and restart it.  Your choice.
