That is the same name as the old Microsoft IIS web server’s location.
Microsoft is making our computers become web servers?
That is exactly what a commenter at the source asked...
“The file is apparently used by Internet Information Services with some users having the folder installed and in use on their computers since 2018. The unusual thing about the current installation via the security update is that it’s now being installed on computers where IIS is either not installed or disabled.”
And another one:
“Didn’t we hear them remaking Recall into CoPilot Vision? Maybe making the desktop computer an internet host will make it easier for Microsoft to spy on you with Recall.”
My first thought as well.
Maybe Microsoft wants to run their own botnet.
Interesting.
