Issue like below:<\/strong><\/p>\n\n\n\n

I have a PowerShell script (that works). In Windows Task Scheduler I created a new task to execute\u00a0\"C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe\"<\/code>, passing the argument as my PS1 script. When the task runs I get a Last Run Result of\u00a00x1<\/code>.<\/p>\n\n\n\n

I updated my script to write to a log file when the script opens and that isn’t happening. It’s almost like the task can’t even open Powershell.exe.<\/p>\n\n\n\n

If the problem you’re having is with Execution Policy, then you can also set the execution policy of a specific invocation of PowerShell. This is what I usually do when executing PowerShell through a scheduled task:<\/p>\n\n\n\n

powershell.exe -NoProfile -NoLogo -NonInteractive -ExecutionPolicy Bypass -File \\\\path\\to\\script.ps1\n\nIf the problem you're having is with Execution Policy, then you can also set the execution policy of a specific invocation of PowerShell. This is what I usually do when executing PowerShell through a scheduled task:\r\n\r\npowershell.exe -NoProfile -NoLogo -NonInteractive -ExecutionPolicy Bypass -File \\\\path\\to\\script.ps1\r\nWhy?\r\n-NoProfile\r\nThis ensures that you don't rely on anything in the user's PowerShell profile, and avoids the overhead of executing that additional code.\r\n\r\n-NoLogo\r\nThis mostly doesn't matter; maybe it does if you're capturing the output of your script. Mostly it makes me feel better.\r\n\r\n-NonInteractive\r\nEnsures that your task won't wait indefinitely if something in your script unexpectedly prompts the user. With this switch, the script will just exit instead; at least you'll have an error code instead of a hanging script.\r\n\r\n-ExecutionPolicy Bypass\r\nYou can use Unrestricted here or whichever execution policy you like. This is probably the one you need the most.\r\n\r\nWhy I prefer setting Execution Policy this way:\r\nBecause I don't want the task to depend on a global non-default setting that you may have other reasons to change in the future. If some other process depends on a different execution policy, then it's not at odds with your task this way.\r\n\r\nPlus it's always nice not to have to change the defaults.
