Basically, I haven't been able to install the last 2 or 3 security updates - the installation keeps failing. This is happening on two relatively new machines running Avast, while on two older computers, I installed the updates without any issues, and they are running the default Windows Defender. Does anyone know what the problem might be or why the installation has been failing for the past 2 or 3 Security Updates? I read somewhere that Windows changed something regarding BitLocker, but I don't see why that would cause the installation to fail.
