Here are some tips from security experts. (These are the most important patches that the company recommends users install immediately).

Microsoft has been limiting support for its older software and is trying to convince users to switch to its more secure and newer Windows 10.

In addition to keeping Windows up-to-date with the latest security enhancements, anti-virus software can prevent malware from infecting your computer.
