Windowblinds 10 is best obtained by purchasing the Object Desktop suite. It includes Start 10 and host of other apps, some of which, surprisingly, don't work with Windows 10. To my knowledge, there is no free upgrade to 10, nor is it available by paying a nominal fee. Like so many other software products today, it appears to be a yearly service, having a countdown starting with 365 from the day of installation. Whether or not ALL the programs in Object Desktop fall under the 365 day restriction, (to me) is a matter of conjecture.
