Windows 7 maximized windows not draggable: how to enable?

On my current Windows 7 install (relatively stock from Lenovo) I cannot click-and-drag on a maximized window and drag it onto my second monitor.

On my older computer (another Lenovo laptop w/Win7 -in the same laptop family) I could do this.

I'm sure there's some Windows config/registry setting that enables "detaching and dragging" of maximized windows when click/dragging on the title bar of a window, but I can't find it on Google or here.

Thanks for any info or ideas!

Solution 1:

Try this under Ease of Access Center.

Turn off this setting.

Solution 2:

You will find that the reason you could drag maximized windows was that your T410 had the nVIDIA screen drivers installed.

I have the same problem now that I have a new laptop: I can no longer drag maximized windows to the other screen and it is really annoying once you have got used to it!

Although this doesn't aid you, at least you now know it is not a Windows setting but something enabled by a 3rd party.
