Windows, in it’s various versions, always seems to be carrying tons of “Remote Code Execution Vulnerability” bugs/patches.
I guess it’s true what they say about Windows: Backdoors are only found when people report them.
No issues on Windows 7 ESU.
No issues to report on two Windows 8.1 Pro systems.
After taking a Macrium image of the system, installed the Servicing Stack Update first (KB5014025) downloaded from the Microsoft Catalog. Then via Windows Update installed the Monthly Rollup (KB5014011) and Security and Quality Rollup for .NET Framework 3.5, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8 for Windows 8.1 for x64 (KB5013872).
