A Few Things I’m Grateful about Microsoft Windows
TL;DR. this is my story with Microsoft Windows, from 3.1 to 7. Many years after my mom bought me my first PC, I realized the Windows 3.1 installed by the vendor was a cracked copy, or pirate copy if you will. But Windows 3.1 was really amazing, and I liked it a lot. There were […]
