As is well known, support for Windows 7 will end on January 14, 2020. This system was released on July 22, 2009, and is now 10 years old. However, its popularity remains high. According to Netmarketshare, Windows 7 is used on 28% of PCs. And since support for Windows 7 is ending in less than three months, Microsoft upgrade offers. These are sent to a large number of users on PCs with licensed Windows 7 Professional.

The message states that the system's support period is ending. After it finishes, Microsoft will no longer provide security updates or technical support for Windows 7. It also recommends creating backups to ease the transition. However, this is just an informational notification that can be disabled. You can check the corresponding box at the bottom left.
Currently, there are two options: upgrade to Windows 10 using a key for free updates or accept the lack of patches. Considering that many are still stuck on Windows 7 and do not plan to switch to something new, the outcome is obvious. However, the same was true for Windows XP in its time.

As of now, it is known that after January 14, 2020, security updates for Windows 7 will only be available as part of paid updates and only for corporate use.
