Thank you very much for sharing this, jaminben.
I went down the route of going back to a version of Chrome that was "stable", but actually being able to dish out updates is much better
I doubt it will be of any use now, but this is a powershell script I was using to clear out the AppData (pointing at "AppData\Roaming\Chrome") of all users on a given PC.
$ErrorActionPreference= 'silentlycontinue'
$pcName = Read-Host "Enter name of PC"
$target = "\\" + $pcName + "\c$\Users"
$users = Get-ChildItem $target
foreach ($user in $users)
{
$item = $target + "\" + $user + "\AppData\Roaming\Chrome"
Remove-Item $item -Recurse -Force
Write-Host -NoNewLine "."
}
# If running in the console, wait for input before closing.
if ($Host.Name -eq "ConsoleHost")
{
Write-Host "Press any key to continue..."
$Host.UI.RawUI.FlushInputBuffer() # Make sure buffered input doesn't "press a key" and skip the ReadKey().
$Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyUp") > $null
}
