Does Test Complete plans to support Windows 10 ?

The short answer is, yes. They recently held a webinar on this. 

Webinar that was posted.

The recording of this should have been posted here:

Recorded webinars.

But I don't see anything that looks like it...Perhaps someone from SmartBear can clarify this.

Hi Adina,

We always support the latest Windows versions after their official release. I don't think that Windows 10 will be an exception.

You can request this feature by submitting it in our new TestComplete Feature Request forum. Other community members can also vote for this idea - it can speed up the implementation process.
