Winabler Portable

Designed as the portable edition of Winabler, Winabler Portable is an advanced and easy-to-use application that can temporarily enable disabled objects in various Windows tools, thus giving you the possibility to test them even if they are locked under normal circumstances.

Portable tool with a simple UI

Since there is no installation involved, you can copy the downloaded .exe file to a custom location on the disk and double-click it to launch the program. It can also be stored on a USB flash drive to carry it with you at all times and run it on any machine.
As far as the interface is concerned, there's a single window available, which shows all options provided by Winabler Portable.

Capture active windows to enable objects

To give control to the app, you can capture the menu structure from a currently running program, in order to test the menu options in this area instead of the source. Worth mentioning is that the application's not compatible with all types of windows out there, as they must meet a certain standard (e.g. graphical menus, which are in fact button bars). Captured menus can be released.

Drag a crosshair to unlock objects

A crosshair symbol can be dragged out of the utility and moved to the disabled object you're attempting to unlock. If the item doesn't seem to become enabled, you can target its parent object instead. As informed by the developer, some objects continuously disable themselves, so it's necessary to keep unlocking them.

Evaluation and conclusion

It left a small footprint on system resources in our tests, thanks to the fact that it needed a low amount of CPU and RAM to function normally. No error dialogs popped up and it didn't hang or crash.
To sum it up, Winabler Portable may come in handy for disabling locked objects from other running programs, as long as you keep in mind that it doesn't work with all types of windows.
