Cheers Steve,
I'll add a link then, it shows in a video how to check/enable via reg editing
I know lots of people are afraid of the registry, but with a video i think anyone can do it without any worries
(before messing with any registry without having to worry back it all up)
If you highlight 'Computer' that's got an icon, then click File tab above, then Export, give it a name eg: 'before messing with core parking' (date too for good measure) (make sure Export range is set to All), then click save, you've now saved the whole registry before messing/altering with it
If you want to restore the reg, instead of doing the Export, just do Import, basically point to where you saved the reg backup
