Hi!
I was testing Google Chrome 31.0.1650.57 stable, and found it doesn't delete all added Registry Keys after closing the browser.
Here is RegShot's log after first run:
----------------------------------
Keys added: 8
----------------------------------
HKU\...\Software\Google
HKU\...\Software\Google\Chrome
HKU\...\Software\Google\Chrome\BrowserCrashDumpAttempts
HKU\...\Software\Google\Update
HKU\...\Software\Google\Update\Clients
HKU\...\Software\Google\Update\Clients\{......}
HKU\...\Software\Google\Update\ClientState
HKU\...\Software\Google\Update\ClientState\{......}
This one is after closing the browser:
----------------------------------
Keys deleted: 5
----------------------------------
HKU\...\Software\Google\Update
HKU\...\Software\Google\Update\Clients
HKU\...\Software\Google\Update\Clients\{......}
HKU\...\Software\Google\Update\ClientState
HKU\...\Software\Google\Update\ClientState\{......}
So, three first keys are not removed.
Same happens with version 33.0.1712.4 Dev
I also tested a backed-up old version 29.0.1547.66, and this one works fine (it deletes all created keys on exit).
