they will NEED to know your OS and Bit 

oh check for Graphic card driver updates

in the windowBlinds interface do you have it set to do transparency? it's under the transparency tab  click on Reset all

and also check under the Explorer Background Tab in  WindowBlinds. click on Rest Opacity levels..  then click on apply changes...  I can't say if it will help but it's a starting point to try.

if that don't work the next 2   I would try is to Uninstall WindowBlinds and reinstall  if still no go then try uninstalling the Graphic card drivers and then reinstall

note restart PC with each if the reinstall don't work then try the hole Graphic Card drivers and Program.

WB and the G- driver is your pick to which to Uninstall / reinstall first...

I would go with the G-card drivers first..  cause it's doing it too all skins  oh and just in case the Driver file you downloaded is corrupted get go ahead and re-down it

if you do uninstall WB run Ccleaner then restart PC then install

Hope something here will help you out...

don't use that one then.. go with an older or newer one  but you already know that...

No Nvidia would have to as you said it only happens with the january 18th version of nvidia.

Try to roll back the nvidia drivers to a previous version or look for updates to the ones you have.
