Thanks out to @SthrnMixer who brought this up on the VC.
According to Microsoft, this vulnerability is impacting all Windows 10 versions, including the most recent May 2021 Update (version 21H1) and version 20H2 (October 2020 Update).
To deploy Microsoft’s patch, you need to check for updates under Updates & Security > Windows Update and apply the latest July update, and reboot the system when prompted.
Alternatively, you can install the emergency update manually from the Microsoft Update catalog if you are unable to do so via the normal Windows Update procedure.
However, researchers have revealed that Microsoft’s patch is incomplete and attackers can still abuse the vulnerability to gain access to the system. Thankfully, you can temporarily disable the Windows Print Spooler service to mitigate the vulnerability until a proper fix is released.
