KB4100375 windows 10

Well, despite all the rumors and inside information regarding the launch date of the Windows 10 April Update, Microsoft changed its mind more than once. Many expected the tech giant to release Windows 10 version 1803 on April, 10 but apparently something came up and Microsoft decided to wait a little bit longer before pushing the red button.

The Windows 10 April Update is now available for download, and the company already rolled out the first ever cumulative update for the new OS version. Update KB4100375 takes Windows 10 to build version 17133.73.

Windows Insiders running build 17133 in the Fast, Slow, and Release Preview rings were the first to download this cumulative update, but now all users can download and install KB4100375 on their machines.
