CS6 on Windows 10 - After DPI Scaling Fix - Tools Icons to small

Dear community members,

after I used the DPI scaling fix (Photoshop.exe-> Comatibilty -> Change high DPI settings -> Check "Override high DPI scaling behavior" > Choose "System") the layout size of the UI is fine.

Unfortunatly the size of the actual tools icons (not in the menue but in the editing window) e.g. the transform or the brush icon are to small. I know about the Interface Preferences as well, but that doesn't seem to do the trick for the actual tools icons in the editing window. 

Does anyone know a solution for this problem? Maybe even an add-on for Photoshop CS6 that could help?

With kind regards.
