Microsoft has released the first Patch Tuesday update for the year, which fixes some critical vulnerabilities present in the operating system. The company said that all users should install the updates right away to prevent attackers from exploiting the vulnerabilities (via ZDNet).
The first two patches fixes known vulnerabilities in both Microsoft Edge and Internet Explorer browser. The first exploit in Internet Explorer allowed an attacker to remotely execute code and trick the user into visiting a specially crafted webpage in order to gain user rights. There are several vulnerabilities patched in Silverlight and Office as well to prevent attackers from exploiting them and safeguard the users.
It's highly recommended that you should install these latest patches through Windows Update as soon as possible to stay safe from attackers.
