Device Manager is running in read-only mode

Today I was creating a template for my VMware environment, when I was trying to change the graphical interface card I was running into some problems. This is the message the Device Manager is giving me.

The result is that I cannot change any drivers or devices.

The solution is very simple but not obvious. My computer name is longer than 15 characters. This is a problem for NetBIOS computers. It turns out this is also a problem for the device manager. So I changed my computer name to a name with less than 15 characters, now everything works normal again.
