Windows schedules task creation issue with powershell

I'm trying to script windows scheduled task creation with powershell, where the schedules tasks call powershell scripts that are in a directory that contains a space. So i need to create with a /tr argument like powershell.exe -noninteractive -command "& 'c:\temp\program files\a.ps1'"

Here is a sample of what i have tried

# Create the script file the schedule task will call, note path contains a space
'set-content c:\temp\program files\a.log "Just done @ $(get-date)"' > 'c:\temp\program files\a.ps1'

$scriptFilePath = 'c:\temp\program files\a.ps1';
$userName = read-host 'user name'; # will need log on as batch rights 
$userPassword = read-host 'user password';

# The following looks good but schtasks args gets messed up so no creation
$taskToRun = "c:\windows\system32\windowspowershell\v1.0\powershell.exe -noninteractive -command `"& '$scriptFilePath'`"";  
$taskToRun
schtasks /create /tn 'ATest' /ru $userName /rp $userPassword /sc MINUTE /mo 1 /st '00:00' /f /tr $taskToRun;

# Gets imported but mangles the tr so instead of 
$taskToRun = 'c:\windows\system32\windowspowershell\v1.0\powershell.exe -noninteractive -command \"& ''' + $scriptFilePath + '''\"';
$taskToRun
schtasks /create /tn 'ATest' /ru $userName /rp $userPassword /sc MINUTE /mo 1 /st '00:00' /f /tr $taskToRun;

If anyone knows how to escape correctly, i would appreciate a hint

Thanks in advance

I'd trade the -command option for -file:

$taskToRun = "c:\windows\system32\windowspowershell\v1.0\powershell.exe -noninteractive -file ""$scriptFilePath"""

Also, the PowershellPack has a TaskScheduler module that's makes task scheduling much easier:

[UPDATE] Thanks

Perfect, just needed to escape with a single quote rather than double quote

$taskToRun = "c:\windows\system32\windowspowershell\v1.0\powershell.exe -noninteractive -file '$scriptFilePath'";
