I am looking at how to move data from a file to a memory stream. This

g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
