Windows 7 has been with us since October 22, 2009. And for a full 10 years, Microsoft provided support for it. That support ends on January 14, 2020. Microsoft will no longer address technical problems or release security updates. Does this mean the end entirely?
Windows will not stop working. It will, however, become vulnerable and unsafe. Thanks to regular updates, you had been receiving security patches that eliminated the risk of your company network being attacked.
What might such a threat look like? For example, the hard drives of a company server being encrypted after an unsecured device is connected.
Summary
An older operating system is used mainly by manufacturing companies in offline mode, where only a simple control program runs. If you operate on Windows 7 in online mode (office work, company email, and the like), upgrading to the latest operating system, Windows 10, presents itself as a solution.
An operating system no longer has to be as costly an item as it once was.
