I've taken much pleasure in shitting on Microsoft and their products for decades, but I'm also the first one to admit the products that are actually good:
Built-in antivirus (for the past 10 years, at least)
Notepad. (Sometimes you don't want any features)
Outlook Express (Newer equivalent is decent, but too buggy and bloated)
Windows 7 (The pinnacle of an MS OS since MSDOS 6.22)
There are probably more, but those are the ones I remember off the top of my head.
