A big issue many users have with Windows apps is that they run full-screen. This can be confusing if you mostly use the desktop environment of Windows 8/8.1. You can easily forget if you have apps running -- and lose track of how many are running -- since there is no obvious indicator on the desktop of this happening. Two applications attempt to rectify this, letting you interact with your apps as if they are traditional Windows desktop applications: ModernMix and RetroUI Pro. Both will run a Windows app inside a re-sizeable window. (Unfortunately, the Windows 8.1 version of RetroUI Pro doesn’t offer this function.) ModernMix is free for 30 days; then $4.99, RetroUI Pro is free 7 days; then $4.95.
