Where is the best place to install applications? By default it seems to be the Programs folder in Windows, but this fills up quickly and I now have little of my initial 20GB OS space remaining.

Moreover, some applications install huge caches and/or temporary files into your system disk no matter where you install the application itself (Adobe suite, many Microsoft programs, Google earth maps, etc.). So, they will still use up space on your OS disk even if you install them somewhere else.
So, a better long-term solution would be to increase the size of your system disk beyond 20GB. That is too small, won't be enough for OS + updates alone.
