WB 10 works on windows 10. WB 7 will not work on 10. Let me put it another way. WB 7 was tried on 10 by a few and nothing but problems besides it not working. So do NOT install it.
WindowBlinds 10 beta is working fine on win 10. If you are an objectdesktop subscriber you can download it. If not you have to wait for the final version and purchase it.
