Windows Update is 100% malware by definition. Remember when Windows 7 had a free upgrade to Windows 10? It would force itself into the update queue with regular updates regardless of the user’s permission, and even after x days after the user explicitly said they didn’t want Windows 10. I worked in a computer repair shop in that time. The Windows 10 upgrade that people didn’t want or agree to often failed, breaking the machine. Sometimes we could recover the installation. Sometimes the OS had to be reinstalled. It was intentionally pushing software in deceiving ways to unconsenting users that broke their machine.

They are the Activator. They need to complete their duty before any of us can use LibreOffice
