Which software do you mean? windows and visual studio 2017 do install fast, also office 2016. Also, "slowly" compared to what? I mean visual studio does install slowly compared to notepad++ for example, but this is due to different package size..(of course)

Office does NOT install fast in my experience. I have downloaded the offline installer in order to not have to download office each time I need to reinstall it, but the installer often spends several minutes using 0% cpu and 0 I/O just saying “we’re getting things ready for you”

Office these days uses App-V with Click to Run for the online installations. The Windows Store version (full) installs really fast tho.

I don't know about the "new versions" of Visual Studio 2017. But VS from 2008 to 2015 installs very slowly (IO wasn't the bottleneck), triple the installation time if the iso file has service packs (I remember that they are applied in "Finalising your setup" progress with bars showing 100%). The latter one is also applies to Office setup.

2017 installs pretty quickly, mostly, I think because you can customize the install for the bits you need. But even then, it's much improved, which is good, because they are pushing large updates almost weekly at this point.
