ok weird one maintenance mode is not supposed to last all afternoon, right?

Windows Update
We couldn't complete the updates.
Undoing changes. Don't turn off your computer.
Error code: 0x800f0922
i started updating WooCommerce from the dashboard. The progress spinner ran for ages, then i clicked away too early. Since then the site is stuck on the maintenance message. i have access to my hosts file manager. Is there something i can safely remove, and how do i know whether the update itself completed? Id appreciate a short checklist of what to verify after its back up.
