I've used PDF X-Change viewer for a while now, less bloated than Adobe Reader.
The reason that it's less bloated is probably because there is no ActiveX/OLE code in it. ActiveX uses a shed-load of memory on initialisation as well, whether you use the facilities or not. Mostly, you dont.

But it is nearly always the most recently installed product that wins...
You're right. If the software is polite, it will ask you if it can override the file associations. Of course, if the programmer who wrote the software is lazy or pushed for time, he won't bother with any of that nonsense. "What? More tests?"

It's a bit naughty to silently change file associations if you don't provide the inter-operability services that other Windows applications use and that Microsoft expects you to have.

I think it depends very much on what software installation framework you use. A good one will do most of the work for you. Adobe have no excuse if they don't give you the option. Maybe they do if you select "custom installation".
