[Fixed] Google Chrome leaves stuff behind

I have never looked at the source, but from what appears there it seems to be a localization problem.

*EDIT*
I have those keys on my machine, Chrome is NOT installed there.

I also have C:\Documents and Settings\Blarg\Application Data\Google\Local Search History

HKCU\Software\Google\Update
That is not a language program.

I though Data\ looked skinny. But those may be releated to the updater. At any rate, I do think that they need to be handled.

GRAWR. I want a good release for once.

I'm confirming this

Geez! You people are PICKY!

OK Let's see what we got here.

HKCU\Software\Google\Common\Rlz

I don't even know what this is, I don't think I'll touch it. Chances are I have more chance of doing damage to other Google apps installed on the local machine (mine has more keys than listed here) than properly cleaning up after Chrome Portable.

It looks like it's part of the DLL that "measures partner distribution deals". Whatever that means. I may clobber it on close regardless of whether or not it existed on startup... I'll need to test stuff to make sure it doesn't break anything when I do that.

HKCU\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}

I will have the launcher remove this key if it wasn't present on startup.

HKCU\Software\MozillaPlugins

Google Chrome checks this key for plugins installed into Firefox, so it can pick up on them and use them (since when it came out plugin installers like Flash didn't install to Chrome, obviously).

HKLM\SOFTWARE\Microsoft\Cryptography\RNG\Seed

Probably related to the password encryption stuff, this key is manipulated by internal Windows APIs.

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Prefetcher\TracesProcessed

Ditto about being set by Windows APIs, not gonna touch it.

C:\Dokumente und Einstellungen\Itunes\Lokale Einstellungen\Temp\chrome_shutdown_ms.txt

I don't have any such file like this in my %TEMP%, hmm... anyways it's probably a small single file in %TEMP% with no "interesting" data in it so I'm not gonna worry too much about it, but I'll take a look at it if I can get it to pop up (I don't have one).

C:\Dokumente und Einstellungen\username\Lokale Einstellungen\Anwendungsdaten\Google\Chrome\User Data

I'll verify this in a VM, if I can reproduce it then I'll have it destroy the directory on quit if it's empty.

It doesn't seem to create User Data but it DEFINITELY creates the Chrome directory one level up. Right now it's looking like it just tries to check if User Data exists. I will check to see what happens if it does not though.

[Edit: It does, I'll have the launcher clean it up.]

In HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463C-AFF1-A69D9E530F96}:
- Reads brand, never writes
- Writes to dr, never reads (always 1?)
- Reads lang. Never writes, doesn't seem to affect actual language (changing language in Chrome still has this value at "en").
- Tries to read referral (doesn't exist)
- Reads and writes usagestats (always 0?)

Since GCP works fine without any of these values in place I'm not going to worry too much. I will just remove the key on quit if it wasn't there when GCP started up.

Both HKLM and HKCU Software\MozillaPlugins are created. I'll remove them both if they are empty on quit.

Tries to read from the following keys, they don't exist on any machine (yet) and it doesn't create the keys so no need to do anything with them:
- HKLM\Software\Google\Chrome\Extensions (globally installed extensions, I guess...)
- HKLM and HKCU\Software\Google\Google Chrome\IndexerPlugins (huh? Maybe Chrome can/will use Google Desktop plugins somehow?)
- HKLM\Software\Google\Update\Client\{8A69D345-D564-463C-AFF1-A69D9E530F96}
- HKLM\Software\Google\Update\ClientState\{8A69D345-D564-463C-AFF1-A69D9E530F96} (both are overrides or fallbacks for the HKCU values maybe?)

HKLM\Software\Google\Update\ClientStateMedium\{8A69D345-D564-463C-AFF1-A69D9E530F96} is created and usagestats is written, but never read. I will delete the key if the only value in it is usagestats.

HKLM\Software\Google\Common\Rlz is opened and a single value read. It's not created if it does not exist, it appears. I won't do anything about this since it's never written to.
