Disk Performance in Task Manager on Windows Server 2012

In Windows 8 the disk performance counters are visible by default in the Task Manager. On Windows Server 2012 they are disabled by default. To enable them, execute the command:

diskperf -Y

A handy shortcut to quickly start the Task Manager is CTRL+SHIFT+ESC.

More information on the source of the Disk Performance Counters can be found in the Microsoft Documentation.

You might wonder why on earth you would do this. Well… I once thought I wanted to be an IT manager, but without the quirks of users using the systems you maintain and design.

After years of consuming the knowledge of wise people, it is time to contribute back to the internet. So there you have it, the start of this blog.

As a developer, the title of your first everything would be nothing else than the famous words that have been written and displayed since binary ancient history: Hello World! And to put it in IT context, I though why not in terms of PowerShell:
