Part of FD-5418. This follows #583, which merged before the fix was pushed.

On a Windows desk, the probe's P6 typing checks failed now and then with agent-desktop (2 of 8 probes): 3 to 5 typed keys didn't arrive.

The cause is in the Windows base, not the driver.

• OneDrive sets itself up at the session user's first sign-in, from the default profile's Run key. It leaves two RunOnce entries behind, each a cmd.exe /q /c del ….
• Windows 11 opens each console command in a Windows Terminal window, which takes the foreground for about 350 ms.
• A composed disk boots afresh every time, so the entries ran at every boot. Input sent with SendInput during that window went to Terminal, not the app.
• Every Windows desk had these windows. cua-driver mostly posts input in the background, so it mostly escaped them.

A watcher inside the guest found the cause. It logged foreground windows and new processes during the probe: explorer.exe started the two cmd.exe at logon, their Terminal windows took the foreground, and the session user's RunOnce held the two OneDrive entries.

What changes

setup.ps1 removes OneDriveSetup from the default profile's Run key, beside the other default-profile settings, before the session user's profile exists. OneDrive never sets itself up for that user. The RunOnce entries, the background OneDrive process and the Terminal windows are gone.

What it costs: the base setup changes, so each machine with a Windows base installs a fresh one once (about 15 minutes), and its Windows desks recompose.

Tests

On an agent-environments-admin box, I installed a fresh base from Microsoft's ISO and composed a windows-11 desk with driver = "agent-desktop":

• Gate 3 passed.
• 8 rounds of the probe at full each passed 52 of 53 checks; P8 leases doesn't apply.
• The watcher, run alongside each round, saw only the fixture and the taskbar take the foreground. No cmd.exe, Terminal window or OneDrive process started in any round.
• The agent task: Claude Code with Sonnet 5.5 saved a line in Notepad through agent-desktop's tools.
• Before this change, the same probe lost keys in 2 of 8 rounds. The watcher caught the Terminal windows in each round and the OneDrive entries in the user's RunOnce.

Confidence Score: 5/5

This PR appears safe to merge.

Summary

Removes startup commands containing OneDriveSetup from the default Windows profile before the session user's first sign-in.

• Windows desks skip OneDrive's setup when the session user first signs in.
