How to speed up Windows 10 (Technical Preview – Build 9926)

If you are a Windows 10 Technical Preview “pioneer”, you will already be loving the enhanced GUI, Cortana and the new Notification Center etc. HOWEVER you might find it goes a bit slow at times and, if you like to keep an eye on Task Manager, you’ll note that CPU utilisation can shoot up randomly – so here are two Woody Gems® for how to remediate that:

Warning: If you are currently running Windows 10 Technical Preview, then this article assumes that you know what you are doing. If you are unused to using regedit or of a slightly nervous disposition, then DON’T TOUCH THAT DIAL – here is a picture of some kittens instead.

2. STOP the Diagnostic Tracking service:

Task Manager

That’s it – Windows 10 Technical Preview will go like the clappers now.
