Oh, man. The "Active" Desktop. The only thing that it kept active was my CD drive when I was forced to reinstall Windows every time I tried to make it work on my PC and it broke everything.
I was all about some 98lite ‘Sleek’ on my hand-me-down 486DX/2-66 in the late '90s, Windows 98/98SE/Me with the original Windows 95 pre-OSR2.5 non-Active Explorer swapped in :)
