Run it yourself

Three steps in PowerShell, four in C#. Every command copies with one click.

Install the module
Once. Windows PowerShell 5.1 or PowerShell 7 on Windows, macOS or Linux.
```
Install-Module ConsoleMonster -Scope CurrentUser
```
Save the program
Download it, or copy it from above into update-compliance.ps1.
Download update-compliance.ps1 View on GitHub
Run it
From the folder you saved it in.
```
./update-compliance.ps1
```

Create a project

A plain console app; .NET 8 or later.

dotnet new console -n UpdateCompliance; cd UpdateCompliance

Save the project
The project selects one C# style at a time and restores ConsoleMonster.
Download UpdateCompliance.csproj
Save both programs
Replace Program.cs and save Program.Fluent.cs beside it.
Download Program.cs Download Program.Fluent.cs View on GitHub
Run it
```
dotnet run
```

Create a project

dotnet new console -n UpdateCompliance; cd UpdateCompliance

Run it
```
dotnet run --property:DemoStyle=Fluent
```

Or skip the copying. Every demo ships with the module and the project template.

Show-ConsoleDemo update-compliance

Export-ConsoleDemo update-compliance -Path ./update-compliance.ps1

dotnet new install ConsoleMonster.Templates

dotnet new consolemonster --demo update-compliance -n UpdateCompliance

dotnet new install ConsoleMonster.Templates

dotnet new consolemonster --demo update-compliance --DemoStyle Fluent -n UpdateCompliance

Make it yours

Start with these, then read the rest of the file.

Fill the server rows from your update tooling's export (WSUS, Configuration Manager or Intune) instead of the inline list.
Change the 30-day overdue rule and the ring names to match your patch policy.
Add a column for the maintenance window so the overdue list doubles as a schedule.
