Well, the default blue** colour background for MS Win2K reminds me of WB 1.3.2 while the GUI**** reminds me of WB 2.X/3.X i.e. smooth metal look.
**The shade of blue is similar.
****With NT 5.X, the “grey” is closer to light grey.
The default MS-mouse setup is two buttons for all Win9X and WinNT 4.0/5.X, just like the AmigaOS.
Most non-MS PC mouse back that time (around the early 1990s) has three buttons while MS-mouse has two.
There’s probably some assimilated ex-Amiga programmers within Microsoft Corp.
