Can't set Chrome as default browser from Powershell

Sarah Scott |

I'm running the following powershell commmand

$chromePath = "${Env:ProgramFiles(x86)}\Google\Chrome\Application\"
$chromeApp = "chrome.exe"
$chromeCommandArgs = @('--make-default-browser')
Invoke-Expression “cmd.exe /C `"$chromePath$chromeApp`" $chromeCommandArgs”

Unfortunatley, when I run this, I get the following error message.

cmd.exe : [1396:2128:0708/153347:ERROR:gpu_info_collector_win.cc(98)] Can't retrieve a valid WinSAT assessment. At line:1 char:1 + cmd.exe /C "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --make- ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: ([1396:2128:0708...SAT assessment.:String) [], RemoteException + FullyQualifiedErrorId : NativeCommandError

[1396:2128:0708/153347:ERROR:shell_integration_win.cc(200)] Chrome could not be set as default browser.

What could be causing this error? I realize there are various ways of executing the command, but the bottom line is that executing Chrome with the --make-default-browser switch is failing.

Adapted from this archived poshcode user script, with which you can switch between Chrome, Firefox, Internet Explorer, Opera and Safari. Add the Set-DefaultBrowser function like this:

function Set-DefaultBrowser
{ param($defaultBrowser) $regKey = "HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\{0}\UserChoice" $regKeyFtp = $regKey -f 'ftp' $regKeyHttp = $regKey -f 'http' $regKeyHttps = $regKey -f 'https' switch -Regex ($defaultBrowser.ToLower()) { # Internet Explorer 'ie|internet|explorer' { Set-ItemProperty $regKeyFtp -name ProgId IE.FTP Set-ItemProperty $regKeyHttp -name ProgId IE.HTTP Set-ItemProperty $regKeyHttps -name ProgId IE.HTTPS break } # Firefox 'ff|firefox' { Set-ItemProperty $regKeyFtp -name ProgId FirefoxURL Set-ItemProperty $regKeyHttp -name ProgId FirefoxURL Set-ItemProperty $regKeyHttps -name ProgId FirefoxURL break } # Google Chrome 'cr|google|chrome' { Set-ItemProperty $regKeyFtp -name ProgId ChromeHTML Set-ItemProperty $regKeyHttp -name ProgId ChromeHTML Set-ItemProperty $regKeyHttps -name ProgId ChromeHTML break } # Safari 'sa*|apple' { Set-ItemProperty $regKeyFtp -name ProgId SafariURL Set-ItemProperty $regKeyHttp -name ProgId SafariURL Set-ItemProperty $regKeyHttps -name ProgId SafariURL break } # Opera 'op*' { Set-ItemProperty $regKeyFtp -name ProgId Opera.Protocol Set-ItemProperty $regKeyHttp -name ProgId Opera.Protocol Set-ItemProperty $regKeyHttps -name ProgId Opera.Protocol break } }
}

Then invoke it with your desired browser like this:

Set-DefaultBrowser cr # cr|ff|ie|op|sa

And you can check that the correct values are set in the registry like this:

(Get-ItemProperty 'HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\ftp\UserChoice').ProgId
(Get-ItemProperty 'HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice').ProgId
(Get-ItemProperty 'HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice').ProgId

I've tested with all 5 browsers with the following versions:

  • Chrome = 39
  • Firefox = 34
  • Internet Explorer = 11
  • Opera = 11
  • Safari = 5

You can use the below PowerShell script to change the default browser to Mozilla:

function Set-DefaultBrowser { Add-Type -AssemblyName 'System.Windows.Forms' Start-Process $env:windir\system32\control.exe -LoadUserProfile -Wait ` -ArgumentList '/name Microsoft.DefaultPrograms /page pageDefaultProgram\pageAdvancedSettings?pszAppName=Firefox-308046B0AF4A39CB' Sleep 2 [System.Windows.Forms.SendKeys]::SendWait("{TAB}{TAB}{DOWN}{DOWN} {DOWN} {DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN} {DOWN} {TAB} ")
}
Set-DefaultBrowser

The following worked for me:

$chromePath = "${Env:ProgramFiles(x86)}\Google\Chrome\Application\"
$chromeApp = "chrome.exe"
$chromeCommandArgs = "--make-default-browser"
& "$chromePath$chromeApp" $chromeCommandArgs

In a search for an answer, I found The Kolbicz Blog which shows how to do this with SetDefaultBrowser.exe. Which is much simpler. SetDefaultBrowser – SetDefaultBrowserand SetUserFTA which sets user choices for default programs.

I've taken the code from @TechSpud and made some changes. Also included some functions from Disassambler's Github Win10-Initial-Setup-Script and removed Safari. I made the changes manually to see the changes made in the registry and observed that along with the Browser ProgID a Hash was changed too:

</dl>

I took all the hashes put in the code and tested. Worked!

BUT after testing again, Edge started to be set as default again and I didn't know why. I thought it was the "marvelous" Windows 10 doing its things, and in a certain way, it is. Every time you set the default browser even being the same browser, the same version, the same machine, the same user profile, doesn't matter if is seconds later, the hash changes. So the code works-ish.

I've found a nice script over here, which you can easily use to change your default browser:

You can find the identifier for Chrome, Edge, Firefox etc. when you have a look at this regkey: HKEY_CLASSES_ROOT\.html\OpenWithProgids

The following code works for GCP Windows 10 server image:

function Set-DefaultBrowser { Add-Type -AssemblyName 'System.Windows.Forms' Start-Process $env:windir\system32\control.exe -LoadUserProfile -Wait ` -ArgumentList '/name Microsoft.DefaultPrograms /page pageDefaultProgram\pageAdvancedSettings?pszAppName=Firefox-308046B0AF4A39CB' Sleep 10 [System.Windows.Forms.SendKeys]::SendWait("{TAB}{TAB}{TAB}{TAB}{TAB} {ENTER}{ENTER} ")
}

WinSAT is the Windows System Assessment Tool. It measures system performance: CPU, memory, graphics, and hard disk speeds and comes up with a single number from 1 to 7.9, that supposed to represent your systems performance. Software publishers (mainly graphics intensive games) were supposed to publish the minimum WinSAT score to get a good experience from their game. (This was the plan prior to Win7, but I don't to what extent it is actually used).

Anyway you can go to the Control Panel, System and you should see "Rating" in the middle of the window. You can click the message next to it to get a rating.

I think Chrome is complaining about not having a rating. (Although it is a big ambiguous whether it is Chrome or CMD) Try rating your system and see if it works.
