I recently made the switch to creating Class-based PowerShell DSC resources. In this, I discovered that each time I use $env:HOMEDRIVE it returns a null value. I tried enclosing it with ‘$()’ but that didn’t help.

&nbsp;

Is there a way to use Environment Variables in the code that I’m missing?

&nbsp;

Thanks in advance,

Russ

DSC resources by LCM runs with system account by default. You will have to run as a specific user to use this environment variable.

Below links will help.

> **[Use Credentials with DSC Resources - PowerShell](https://docs.microsoft.com/en-us/powershell/dsc/configurations/runasuser?view=dsc-1.1)**
>
> DSC allows you to provide credentials to a configuration so that configuration settings can be applied the in the context of a specific user account rather than the Local System account.

Thanks kvprasoon. That makes perfect sense.
