Finally, with the arrival of January 14, 2020, the ten-year-old Windows 7 operating system has officially retired. Starting today, Microsoft will officially discontinue support for Win7, which means that users can still use this classic operating system normally, but Microsoft will no longer perform any reason and update.
Microsoft stated that "after January 14, 2020, Microsoft will no longer provide security upgrades or support for computers with Windows 7 installed." Windows 7 was born in 2009, and it has been more than 10 years. 10 years of maintenance, so the impact of this outage is not small.
