Microsoft Urges Customers to Update Windows as Soon as Possible

By on Jul 08, 2021

What happened  

Microsoft has shipped an emergency security update affecting most Windows users. This update partially addresses a security vulnerability known as PrintNightmare that could allow remote hackers to take over your system.  

How does this affect you?  

PrintNightmare could allow hackers to gain control of your computer. This means hackers could perform malicious activities like installing their own apps, stealing your data, and creating new user accounts.  

How to fix the issue

Microsoft recommends Windows 10, 8.1, and 7 users update their computers through Windows Update as soon as possible. Note that an additional patch will likely be required to fully fix the issue, so expect another update prompt from Microsoft in the days to come. 

Additional protection
