Microsoft just released its first round of Patch Tuesday updates this year and you should update your Windows PC right now to stay safe.

Microsoft fixed over 150 vulnerabilities on Update Tuesday in January. These include 11 security vulnerabilities categorised as critical and several Windows vulnerabilities that are already being exploited for attacks.

With these critical security flaws in mind, you'll want to update the browsers ASAP. To update Chrome on the desktop, click the three-dot icon at the top, move to Help, and then click About Google Chrome. The browser will automatically install the latest update and then prompt you to relaunch it.

All three zero-day vulnerabilities have a CVSS score of 7.8 and could allow an attacker to gain system privileges.
