When you have a machine like I do that has a CPU capable of
Turbo or other overclocking, then one may want to only “activate it” when really needed. This way one can avoid unnecessary fan spinups and heat.
My default CPU clock is at 2.8Ghz and capable to boost up to 3.6Ghz. To avoid always going back to the
BIOS and turn the
Turbo feature on and off, I have found an easier way to throttle down frequency within the
Power options menu.
On this video I show you an easy way to create a custom power scheme and set the CPU throttle values:
As shown on the video you can realise it’s only to change the CPU speed from 100% (with Turbo) to 99% to throttle it to the default frequency. It’s just that 1%, really! :)
To further modify/delete power schemes you really have to go to the command line.
To delete a scheme:
First let’s list all of the schemes to get their UUID:
results in the list:
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced) Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (High performance) Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a (Power saver) Power Scheme GUID: dc512798-8638-4c98-9432-5e0e744ab01b (Game) *
Let’s delete Power Saver (you can’t delete the current one, marked with *):
powercfg /d a1841308-3541-4fab-bc81-f71556f20b4a
Changing power schemes with a click of the mouse
You can also create a few shortcuts to change between power schemes with just a line like this as the command:
cmd /c "powercfg /s dc512798-8638-4c98-9432-5e0e744ab01b"
This is useful when you use more than 2 schemes, because the taskbar icon only let’s you change between the most recent 2 of them.

This tutorial is based on using Vmware Workstation 11 on Windows 8.1 host using an Ubuntu 14.04 guest. Note: you have to have the vmware tools, client additions installed on the quest machine!
First go to the Vmware client's terminal when you are ready to shrink it down and type:
sudo vmware-toolbox-cmd disk list
This will give you the mount points that can be shrinked individually.
For me I will only go with shrinking the main disk with "/" (root).
First lets wipe the free space clean so the shrinker will know what is free to get rid of:
sudo vmware-toolbox-cmd disk wipe /
sudo vmware-toolbox-cmd disk shrink /
That's it, after the process in my case I've had a 4.4G file shrinked down to 1.7G, which is much closer to what the client OS saw (1.5G).

Ok now, let's see how these tags translate on the report UI.
First we are seeing failed results.
