Hi Rout, Subham,
In VDI/FSLogix environments, even when installed per-machine, OneDrive runs a lightweight setup routine (like OneDriveSetup.exe /thfirstsetup) every time a user logs in or attaches their profile.
This routine ensures the user's profile is configured correctly. In doing so, it touches and updates the uninstall registry keys for OneDrive under HKCU. Windows natively monitors these keys, and when they are modified, Windows automatically updates the "Installed Date" displayed in Apps & Features — even though no actual reinstallation or version upgrade occurred.
Stop looking for that exact quote. If you need to explain this to an audit or security team, explain the registry-touch behavior during the logon process. If this helps clarify the mystery, please click "Accept Answer".
