How to stretch or scale a windows to fit resolution height and width sizes?

I used to use Sizer, which works well for this. Unfortunately, there is no version for 64-bit Windows, so I do not use it any more, and I am unaware of anything similar.

Using the Win++ and Win+- keys should work fine for you if you do not care about the rest of the applications while you are scaling this one up. The Windows 7 Magnifier tool can be set to full screen zoom, with almost any zoom factor, and it does not disable any interactions or animations. You can also set it to not follow the mouse pointer or keyboard focus, so the view is fixed once you have everything set up.

If you see a docked window, press Ctrl + Alt + F to switch to full screen view. Note that this is only valid for Windows 7 with Aero enabled. Windows XP's magnifier is always a docked window with no interaction.
