There was a safeguard hold on Symantec by Microsoft. The firm had blocked Norton antivirus users or Symantec from the latest update of Windows 7. This also includes the Windows Server 2008 R2 devices.
The block happened because of Windows update, which was code signed using SHA-2 certificates that were deleted during the installation. That is on Windows 7 SP1.
Microsoft did say that the software may not correctly identify files including the updates. This will lead to the risk of the update being delayed or incomplete.
Further, Microsoft did mention that Bluetooth speakers will not be working when it is connected to Windows 10. This is after the installation of the 1903 devices, which is the KB4505903 cumulative update that had come on July 26, 2019. A warning did come from Redmond regarding Windows 10 on August 24. The earlier versions are said to end by October 9, 2019, and that is why the latest version seems to be important now.
The throttled update delivery system is currently being tested by Microsoft along with the Windows 10 19H2 Build 18363.327. The industry is growing and Microsoft isn’t behind. Being a big player it is still making sure it has a good grip over the industry.
