Run the vendor uninstaller first, ideally elevated. Reboot if the installer demands it; skipping that step often leaves services locked.
Open the leftover scan only after the program is closed. Sort results by path and prefer removing folders that still carry the publisher name you recognize.
For registry suggestions, export a backup, then remove keys in small batches. If something breaks, import the backup from a recovery session.
Keep a simple text log (date, product name, paths removed) if you support family members remotely. It saves hours when someone asks why a game stopped launching two weeks later.
When two products share one install folder (rare but messy), remove the product you no longer want first, then rescan; do not delete the parent directory until both uninstallers have run.
Read the list like evidence, not a shopping list. Legitimate leftovers often include the vendor name, version folders, and uninstall logs. Generic paths such as Temp or broad Visual C++ redistributable keys deserve extra pause—other installers may still reference them.
Work in layers: delete obvious empty install directories first, reboot if the product had a filter driver or shell extension, then run a second scan. Many “new” lines after reboot are stale handles that only appear once files unlock.
When a tray app refuses to show in Programs and Features, use Hunter mode to identify the real executable, uninstall from the correct entry, and only then trust leftover paths that match that binary’s publisher.
On laptops, check both AC and battery profiles if power management software leaves services behind; some vendors install duplicate stacks per power scheme and the leftover scan may surface both.
If you are helping someone non-technical, export the leftover list to a screenshot or PDF before cleanup. That snapshot becomes your rollback map if a game launcher suddenly “cannot find components” a week later.
Check context columns, not only the path string. The same folder name can appear for a trial and a paid SKU from one vendor. Match version numbers in the path to what Add/Remove Programs reported before you removed the product.
Antivirus and game anti-cheat hooks sometimes register as leftovers even while still active. If a path points at a driver store package (oem###.inf style), stop and read the vendor’s uninstall doc instead of deleting random .sys pairs.
Cloud-synced “Documents” folders can mirror deleted shortcuts back from another PC on the same account. Pause sync briefly if you see the same desktop icon return minutes after cleanup.
When nothing looks wrong but disk space is still flat, compare sizes before/after in Settings → Storage, then revisit Disk space after uninstall for caches the scan will not reclaim automatically.
