I did a search and replace of all the occurrences of chrome.exe in my registry with the specific command link. So,

"C:UsersPROFILE-NAMEAppDataLocalGoogleChromeApplicationchrome.exe" -- "%1"  

was replaced with

"C:UsersPROFILE-NAMEAppDataLocalGoogleChromeApplicationchrome.exe"  --user-data-dir="C:Chrome Profile location" --omnibox-popup-count=10 -- "%1"

everywhere and so far haven't run into any troubles. But there should definitely be a more easier/elegant way of doing this.

Add a key of type REG_SZ (string) called UserDataDir under

HKEY_LOCAL_MACHINESOFTWAREPoliciesGoogleChrome

with the value of the user-data-dir that you'd like to use. The can be done with a single command line from the Command Prompt, as follows:

reg add "HKLMSOFTWAREPoliciesGoogleChrome" /v UserDataDir /t REG_SZ /d "C:UsersUser1chrome-profile" /f

The profile specified will be used as the default when Chrome is launched. This is confirmed to work in the current version of Chrome as of this writing -- version 70. The UserDataDir key was introduced to Chrome in version 11.

This way you don't have to use any command line arguments to chrome.exe and so you don't need to change the shell handlers for the various file types that chrome opens.

The Solution that works for me is to

Open Regedit

Navigate to HKEY_CLASSES_ROOTChromeHTMLshellopencommand

Edit Default key Value to add --profile-directory varaible

i.e.
Modify Default key Value data as:
"< path to Chrome.exe >chrome.exe" --profile-directory="< *name of your default directory* >" -- "%1"

There's an explanation of how to use multiple Chrome profiles here.

The gist of it is to look inside

%USERPROFILE%Local SettingsApplication DataGoogleChrome

(Windows XP)

or

%USERPROFILE%AppDataLocalGoogleChrome

(Vista, Win7)

and copy the "User DataDefault" folder to "User Datayour_profile".

Then run chrome with some command-line options:

chrome.exe --user-data-dir="..User DataYour_profile" -first-run

and thereafter, you can run Chrome with that profile by using:

chrome.exe --user-data-dir="..User DataYour_Name"

And you can add that --user-data-dir option to a shortcut.

Now how you would use that setup for the default browser, I don't know. Might involve some tinkering in the Registry, around HKEY_CLASSES_ROOThtmlfileshell

I adopted the solution proposed by Rehan Khwaja above. Following the steps below will make Chrome launch from your new user location, you DO NOT need to edit shortcuts or any of that.

My exact steps were:

1. Create the folder structure you want use, for instance:

Y:ProfilesChromeMyUserDataProfile



2. Follow Rehan Khwaja's steps in the registry by opening registry editor and creating this structure:

HKEY_LOCAL_MACHINESOFTWAREPoliciesGoogleChrome

(I had to add the GoogleChrome part as follows)

a) Right click on 'Policies' in the left pane of the registry editor

b) Select 'New Key' and call it: Google

c) Left click on your new key called Google (in the left pane of the registry editor, might have a folder icon next to it)

d) Now repeat steps a to c but left clicking on: Google, and creating a new key called: Chrome



3. Once you have the key called Chrome:

a) left click on it in the left pane of registry editor

b) right click in the RIGHT pane, and

c) Select: New > String Value

d) Name the string value: UserDataDir

e) Right click on your newly created UserDataDir

f) Select modify...

g) Under Value Data enter the path of your folder structure, for instance:

Y:ProfilesChromeMyUserDataProfile

h) Select Ok

i) Close registry editor

Google Chrome will now launch from:
Y:ProfilesChromeMyUserDataProfile
(by default, using all your standard shortcuts without having to edit their path's etc).

If you want to replicate your existing browsing environment in this new profile location, you can copy the entire contents of your old profile (or Chrome's default one) into your new path.

Windows 7 or 8 - Default Chrome Install
Copy everything from:

%USERPROFILE%AppDataLocalGoogleChromeUserData

into

Y:ProfilesChromeMyUserDataProfile

If you want to launch Chrome from different profiles with separate shortcuts for each, you will have make the shortcuts and edit the path's etc (as suggested in other posts).

Windows Solution

If you are using --user-data-dir for your shortcuts already, then this is what you're looking for.

This will make http:// and https:// links in other applications (eg. Skype) open in Chrome with the profile specified.

1. Open Regedit (Run / WIN + R, type regedit, press enter)



2. 
   

   Locate the following keys:

   
   
   
   
   
   • HKEY_CLASSES_ROOThttpshellopencommand
   
   
   • HKEY_CLASSES_ROOThttpsshellopencommand
   
   
   
   

   Edit the (Default) values of these keys to this:

   
   
   

   
   

   "YOUR_CHROME_PATH_HERE" --user-data-dir="YOUR_USER_DATA_PATH_HERE" -- "%1"

   
   

   
   
   

   Replace YOUR_CHROME_PATH_HERE with your Chrome.exe path, eg.

   
   
   

   
   

   C:Program Files (x86)GoogleChromeApplicationchrome.exe

   
   

   
   
   

   Replace YOUR_USER_DATA_PATH_HERE with your Chrome User Data Folder, eg.

   
   
   

   
   

   P:LibrariesChrome Profile

   
   

   
   
   

   The default Chrome User Data Folder is located in

   
   
   

   
   

   %LOCALAPPDATA%GoogleChromeUser Data

   
   

   
   
   

   Note: Can't use %variable% in Regedit.

   
   

The way I get around this is

1. 
   

   If you want to open a particular profile rather than Chrome picking up the last open profile:

   
   
   
   
   

   • Follow the steps mentioned here to create a custom icon for your profile : https://superuser.com/a/723145/84229

   
   

   • Open whichever profile you want with the corresponding icon.

   
   
   
   


2. 
   

   If you are concerned about which profile is picked up by an external program

   
   
   
   
   

   • Swap the names of Default & Profile 1 directories here %LOCALAPPDATA%GoogleChromeUser Data

   
   

   • i.e. rename Default to DefaultTmp, rename Profile 1 to Default, rename DefaultTmp to Profile 1

   
   
   
   

For multiuser systems with roaming profiles (ie. Terminal Server)

use:

reg add "HKLMSOFTWAREPoliciesGoogleChrome" /v UserDataDir /t REG_SZ /d ${roaming_app_data}Chrome /f

environment variable %appdata% wont work via registry.
So use ${roaming_app_data} instead.

There is a setting within a global preferences file in the Chrome AppData directory that updates a "last_used" variable with the most recently used profile. You can reset/override this setting by setting it to your desired profile and it should simply use the profile you specified on the next app open. Otherwise using --profile-directory="Default" or --profile-directory="Profile 1" on your shortcuts will force a new window using that profile. You should NOT use --user-data-directory, as that is something completely different (sets/overrides the cache and settings directory path which the profile should already have defaults for).

The file mentioned above is the Local State file, which you could potentially parse to replace whatever profile is selected as the last used with your desired profile. See https://superuser.com/a/436262/333828

I have a solution for MacOSX. I have used an Automator to create Folder Action on ~/Library/Application Support/Google/Chrome. When the Chrome application quits, it creates some unimportant shutdown file in this directory. This triggers a folder action. If the last profile used was not the Default it runs this script, to modify saved profile:

cd ~/Library/Application Support/Google/Chrome

if ! grep '"last_used": "Default"' Local State >/dev/null; then

    sed -e 's/"last_used":.*/"last_used": "Default",/' 

        -e 's/"last_active_profiles":.*/"last_active_profiles": [ "Default" ],/' 

        -i .bak Local State

    say "Chrome Default Profile Set"

fi

Next time you start Chrome (anyhow), it will start with the Default profile.

For the sake of completeness, I'll add another solution which aparently did work in the past, but at least for me (WinVista, Chrome 31) does not.
http://productforums.google.com/forum/#!topic/chrome/4F9bjXogI0s

The solution is to make the User Data folder a hard-link (an NTFS junction) to your actual profile folder, like this:

mklink /J "C:Users<user_name>AppDataLocalGoogleChromeUser Data" "C:myDefaultGoogleProfile"

• Open Chrome


• Top right corner of the browser click the icon that looks like three horizontal lines and in the drop down menu select "Settings."


• Select "DISCONNECT YOUR GOOGLE ACCOUNT" at the top of the screen that appears.


• Click through the prompts to complete the account removal process.


• When there are no accounts associated with Chrome re-add the account you want to use as the default one FIRST then any subsequent accounts you want after that.


• That is what I did to make MY preferred user profile be the one active when launching Chrome.

For Windows 10, I modified the following registry keys:

HKEY_CLASSES_ROOThttpshellopencommand

HKEY_CLASSES_ROOThttpsshellopencommand

HKEY_CLASSES_ROOTChromeHTMLshellopencommand

All with this value:

"C:Program Files (x86)GoogleChromeApplicationchrome.exe" --profile-directory="Default" -- "%1"

And just an extra note, none of it worked until I modified the last key (the third above) HKEY_CLASSES_ROOTChromeHTMLshellopencommand, so that may be all that was needed. I only found that key because of this answer.

There are a lot of answers here but most of them seem to use HKEY_CLASSES_ROOT. This is a legacy key and really shouldn't be used any longer (to put into perspective, HKEY_CLASSES_ROOT comes from Windows 3.1 and was intended for backward compatibility). The correct place to make these changes is under HKEY_CURRENT_USERSoftwareClasses.

As mentioned all over the place here, Chrome stores each "profile" in its own directory. When launching, the --profile-directory command-line switch can be used to select a specific profile directory. Without this switch, Chrome will simply use whichever profile was last used. The default profile (the first user you logged in as after installing chrome) is always stored in the directory "default".

The simplest method for setting a profile is to simply edit Chrome's shortcut and add the command-line parameter --profile-directory="default":

"C:Program Files (x86)GoogleChromeApplicationchrome.exe" --profile-directory="Default"

The downside with this approach is that it only affects the shortcut itself. If Chrome is your default browser, and another application opens a page, this will have no effect. Similarly, if you associate a local file extension with Chrome, it will not affect which profile is selected when opening that file type from Windows Explorer.

The fix for this is to specify the profile to use in the Windows Registry. In order for this to work for both mapped extensions and shell execution, we need to make a change in two different places:

1. HKEY_CURRENT_USERSoftwareClassesApplicationschrome.exeshellopencommand




2. HKEY_LOCAL_MACHINESOFTWAREClassesChromeHTMLshellopencommand

The default value for both of these are the same:

"C:Program Files (x86)GoogleChromeApplicationchrome.exe" -- "%1"

Just as with the Shortcut method discussed previously, we simply need to add the --profile-directory="default" switch. One difference, however, it that here we need to add it between "chrome.exe" and -- "%1":

"C:Program Files (x86)GoogleChromeApplicationchrome.exe" --profile-directory="Default" -- "%1"

For a quick-n-dirty solution, create a file called ChromeDefault.reg and copy & paste the following into it:

Windows Registry Editor Version 5.00



[HKEY_CURRENT_USERSoftwareClassesApplicationschrome.exeshellopencommand]

@=""C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default" -- "%1""



[HKEY_LOCAL_MACHINESOFTWAREClassesChromeHTMLshellopencommand]

@=""C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default" -- "%1""

Once saved, double-clicking this file will automatically make the necessary changes to your registry. This simply saves you the trouble of walking through the tree in RegEdit.

I found an easy solution to this. I'm running Chrome Version 33.0.1750.117 m. I found that when I open my 2nd profile, Chrome creates another task in the Windows 8 task bar and the new Chrome task has a barely perceptible icon difference, it has the profile picture you've chosen for your new profile. In my case, there's a tiny Superman on the lower right corner of the Chrome icon.

Simply pin that icon to to your task bar and unpin the old icon.

I have tested this and it works for me. Even if the last instance of Chrome I close out is the old profile (which I am retaining), the new profile is opened when I open Chrome.

It's way easier than that -- just go into the Chrome users, click on the user you want to be default, and click the "Edit" button. Then, click to create a desktop shortcut that will make a shortcut straight to that user. Bingo!

No way to do it. Chrome always opens any external link from the active user or the last user you have switched to.
