"What is this?"

I started using a computer when I was 4-ish
My very first Windows OS was Windows 7
I thought it came out in 2014 until 9 (was a week away from my 10th birthday) year old me googled its release date and found out it came out the EXACT same day as my date of birth. (Even made Moscovio May having the same date of birth as me canon)
And i knew how to type when i was 5-6-ish.

I used a computer when I was 5

Cool
Did it run windows 7? Or you forgot.

It was ChromeOS

Wow ChromeOS is rarer than windows
I use ChromeOS at my school.

I normally use chromeos

For Chromebooks
For me it's Microsoft Windows 99% of the time
1% is ChromeOS (school days only)

ok
