White boxes for icons in Notification Area

Running Win 10, build 16299. I used a program, "Dir Icon" to change the icons in the Notification Area" of This PC.
I opened My PC on startup last week and all the drive icons had turned into white square boxes.

I tried everything I could find to repair the icons, even the Reset Notification Area Icons Cache. I did a Repair Install of Win 10 to try correct this and other problems but it did not solve the problem.

Would anyone have a solution?

Thanks for any help

Just curious.......
What if you uninstall "Dir Icon" and do a reboot afterwards.

Thanks davidhk for the quick reply.

This is one of the things I tried. I uninstalled "Dir Icon" before the repair of win 10 and then downloaded a new ver.

I have found that I can change icons that are contained within the drives that will not change. Also. icons that are on the desktop do not change after using the "new" Dir Icon.
