This installs a small agent (a PowerShell script run by Task Scheduler) that checks in with the Mac Mini over HTTPS so its AI agent can manage this computer. Nothing on this PC listens for connections; the PC only makes outbound requests to win8.ashavolian.com. Works on Windows 7, 8, 8.1 and 10.
If it fails with a certificate or trust error, this PC lacks the Let's Encrypt root certificate. The chat also gives a hash-checked one-liner that installs it; run that first, then retry.
What gets installed: C:\ProgramData\win8-bridge\ (agent.ps1, launcher.ps1, a token, logs) and a scheduled task named win8-bridge. To remove it, run uninstall.cmd from that folder as admin. Source: setup.ps1 (needs a code), VERSIONS.txt.
