This command is a PowerShell command that retrieves a list of all available modules on the system and filters out any modules whose names start with "Microsoft" or "PS".

Here is a breakdown of the command:

1. Get-Module: This cmdlet is used to retrieve a list of all loaded modules or all available modules on the system.
2. -ListAvailable: This parameter is used to specify that only the available modules should be listed. If this parameter is not provided, it will also include the loaded modules.
3. | (pipe): This is a pipeline operator that takes the output from the previous command and passes it as input to the next command.
4. Where-Object: This cmdlet is used to filter the objects that are passed through the pipeline based on a specified condition.
5. { $_.Name -NotLike "Microsoft*" -And $_.Name -NotLike "PS*" }: This is a script block that represents the condition for filtering the objects. In this case, it checks if the name of the module ($_.Name) does not match the pattern "Microsoft" and does not match the pattern "PS". -NotLike is the comparison operator used for pattern matching, and * is a wildcard character that matches any number of characters.

So, the command essentially retrieves a list of available modules and filters out any modules whose names start with "Microsoft" or "PS". The resulting output will be a list of modules that do not have these patterns in their names.
