First I found that ngentask was repeatedly running 32-bit ngen and it's practically impossible to debug what's gone wrong so I've replace the ngen with a dummy exe.

But it still does it, now instead of ngen it's simply "System" constantly burning 20% cpu for whatever utterly pointless maintenance task it's decided on that's obviously broken.

It's just really frustrating, I swear that the "idle" mode of win 10 costs me far more money than actively using the laptop. And it's so hard to debug because as soon as the computer activates it stops whatever bullshit it was doing.

On my desktop I tried ripping out all the privacy invasive stuff and have somehow managed to break the start menu search.

I do like it more than Win 7, the startup time's great, but it's still really frustrating at times.
