You most definitely do NOT have to install the Windows Phone junk.
Quick and dirty screen shot. The difference is a whopping 8GB, too. Default selections under Custom takes 8GB. Add the Phone crap and it goes to 16GB. And some stuff can be pointed to a drive other than C:.
SSDs are cheap these days, no sense to constrict yourself anyway. I have all that stuff, plus a full install of SQL Server, plus standard Office apps, KiCAD, Arduino IDE, and more, and it could al fit on a 256GB SSD, though I have a 512GB in this machine. Same stuff plus a few games on my home machine and that one actually DOES only have a 256GB SSD. In fact I have 2 versions of Visual Studio installed on that one because I wanted to use the OLD VB for a project (VS 6.0), but just VB and the IDE out of it.
