Fun fact: Before Windows XP, the default Windows installation directory on NT versions was C:\WINNT

[Nir Lichtman @nirlichtman_]

Fun fact: Windows 2000 dropped the NT from the Task Manager name as part of a re-branding

Fun fact: Windows 11 Notepad still has the "F5" Time/Date keyboard shortcut dating all the way back to Windows 1.01 (1985)

This is one of the best tech youtube channels. Like, actual tech. Debugging Windows kernel (yes, Windows kernel!), drawing graphics with assembly, creating Linux distros from scratch. With all first principle sources.
It's a crime that Nir doesn't have 100k subs!

@valigo Thanks Valentin!!

Just got this 1999 Sony Vaio N505AS from Japan, stay tuned for next video!

Fun fact: You can browse to "about:about" on Chrome to get all kinds of interesting internal pages, you can even do this on mobile devices
