steamwebhelper
steamwebhelper.exe is the Chromium/CEF process that renders Steam's user-facing UI: the store, the library, the friends list, in-game overlay panels, and most non-trivial dialogs. Steam's UI was rebuilt on this Chromium foundation in 2023 (the Steam New UI rewrite), which is why you typically see multiple steamwebhelper.exe processes in Task Manager: a primary plus per-tab and per-overlay sandboxes.
The high RAM and CPU usage that sometimes draws attention to this process is the Chromium runtime doing UI work, not a sign of misbehavior. If you have Steam installed, multiple instances of this process are expected whenever Steam is running.
Catalogued from Vera's own observations across real sessions, surfaced only after the process has been seen on multiple independent machines. The reported publisher and category come from the process itself and Vera's curated app catalog. File paths are never published.
