Internet Security

Microsoft’s next big update for Windows 10 (May 2020 Update) is just around the corner and the Redmond-giant has already released the downloadable ISOs for IT Pros via the MSDN.

People spent half of their life browsing on the Internet these days and protecting your data from threats like eavesdropping and spoofing has become a top-priority for security experts.

In order to ensure a solid line of defense against DNS exploits, Windows Insiders with Build 19628 (or higher) installed on their machine can now try out the Windows DoH client (DNS over HTTPS) that is built into the operating system.

To know what build and version of Windows you are running,

typing ‘winver‘ in a Run window will yield the results, as shown below.
