Microsoft Teams
Microsoft Teams stores a mix of Chromium and app-specific data under its profile, including HTTP disk cache entries, IndexedDB and Local Storage records, GPU shader caches, and SQLite databases with write-ahead log and shared-memory files. These files speed up sign-in, channel rendering, media previews, and web content inside the app, but stale browser storage, invalidated GPU cache data, and bloated SQLite files can cause loading failures and sluggish behavior. Kudu clears disposable Teams cache data and compacts its SQLite databases with VACUUM, without touching your account, messages, files, or saved settings.
Why clean Microsoft Teams?
- Corrupted Chromium disk cache entries can leave Teams stuck on a white or spinning loading screen because the app keeps reusing bad web assets instead of fetching fresh ones
- Stale authentication and web storage data can trigger repeated sign-in prompts, tenant switching glitches, or a loop back to the login page even though your account is valid
- Invalidated GPU shader cache after a graphics driver update causes black panels, flickering video windows, or a sluggish first launch until Teams rebuilds the cache
- Oversized IndexedDB and Local Storage from long-lived sessions can make chat lists, channel tabs, and search results appear late or fail to refresh until cached state is reset
- Broken cached thumbnails and media responses can cause missing profile pictures, blank image previews, or attachments that only open after a manual reload
- SQLite databases accumulate free pages and fragmented page layout over time; VACUUM rewrites the database file without deleting rows, which can reduce disk usage and improve startup or search responsiveness
- Leftover write-ahead log and shared-memory files from an unclean exit can make recent UI state inconsistent, such as unread counts or conversation panes not matching what the server shows
Cache paths Kudu targets
These databases are vacuumed (compacted) — no data is deleted. SQLite VACUUM reclaims wasted space left over from normal usage.
