AHK takes a bit more memory, i used for a few months and finally give up...
let us know what utilities you must have with your pc
i have 3 must-have toos
1. ALTRun(Keyboard hotkey tool, chinese-developped, called ET Worker)
much stronger than langcher and less than 1M...non-tech to use,
takes almost 0 resource(as StrokeIt)...chinese and english lang supported,
it has a tool called winctl.exe(a window-control tool), can do almost everything with window, max/max all, min/min all, hide/hide all,show/show all, close, top/untop, move, transparent and much more, support window handle,title and class
2. StrokeIt(Mouse gesture tool), work with ALTRun, one controls keyboard, the other controls mouse, perfect...
3. Total Commander, no need to say anything...
of cause, with nircmd, i can simplely do much more...
