@tomxcd Install? Somewhere between Oct 2011 and March 2012 (I think early 2012), cuz Ubuntu 11.10 was my first ever exposure to Linux using WUBI

Switch? Around 2019

My main OS was Windows 7 at that time, tried to switch to Windows 10 like 5 times but it was always buggy and slow (especially on a mechanical HDD)

Microsoft announced that they're gonna stop supporting 7 soon, so left with the choice of using a buggy broken OS or biting the bullet and switching to Linux... Yeah
