In this screenshot, you can clearly see how Windows drops a shadow for icon labels:
Enabling and disabling drop shadows for icon labels is very easy. You need to open the Performance Options / Visual Effects settings and make your choice there. But it did not seem to be working for some. If you are facing this problem, then you can tweak the registry to achieve the results. We tried it, and it worked like the charm. This is how you can go about it:
Cannot remove Drop Shadows for Icon Labels
Press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.
Navigate to the following location:
In the right pane of this location, you’ll see the ListviewShadow named DWORD (REG_DWORD) having the Value data as 1. Double click on the same DWORD to modify its Value data, you’ll get this:
In the shown box, put the Value data as 0 and click OK. You may now close the Registry Editor and reboot the machine. After reboot, you’ll find that there are no drop shadows for Desktop icon labels, as expected. We hope this helps you resolve your problem.
