Q. Is this really as harmful as you think?
A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.
If employees are using the corporate’s computers, they can already see everything the employees do, they don’t need this new window feature to do it
That is by no means necessarily the case. For example, if a notebook is taken into the field and is not on the LAN.
A lot of companies are implementing better VPN tech (like SD-WAN, Nebula by Slack, etc), or at the least Microsoft Intune to ensure your corporate laptop is reachable anytime it’s connected to the internet.
My work laptop is a brick until it establishes a VPN tunnel back to the home network. There are ways to ensure the device only works how the company wants it to.
