In fact, this month’s round of updates, which will roll out to machines running versions 20H2 (or the October 2020 update) and 2004, also contain fixes for over 83 security vulnerabilities in Windows and other enterprise tools, which is why it is recommended that users download the update immediately. Most importantly, the January update also plugs a big security flaw in Microsoft’s otherwise capable Windows Defender antimalware scanner that is built into the operating system. The other areas receiving patches include Windows Storage Service, Windows Peripherals, the Windows App Platform and Frameworks, Windows Cryptography, Windows Fundamentals, and Windows Hybrid Storage Services, according to Windows Central.

Also read: Microsoft fixes bothersome Windows 10 reboot bug Users who are wary of updating could possibly defer their update by 7 days using the pause updates feature, which will allow them to keep an eye on any issues that emerge in the coming days, but given the important fixes in this update, waiting may not be a good idea especially if you need your device to be secure for work purposes. Microsoft will also issue an update to finally get rid of the now outdated Adobe Flash Player, which was finally killed off on December 31, 2020. The update KB4577586 is designed to do that for you, but you can simply head over to Microsoft’s website and download it yourself. Flash player needs to be completely removed, as Adobe’s discontinuation of updates makes it a huge security risk on any computer going forward.
