As usual for an invasion of privacy or violation of fundamental rights, the UK got there first. In England, you get your DNA taken and stored simply if you get arrested - you don't even need to be charged, let alone convicted.

Apply the patch update and change the options to disable vita chambers. Now death means death.

I scanned through the comments and didn't see this mentioned yet, so...

Check if the processor speed is being throttled. I once saw a laptop that seems to have the symptoms you described - everything going slow, processes taking lots of CPU time.

It turned out something was wrong with the power management and it was keeping the CPU at the minimum speed permanently. Setting the power profile to "Always On" fixed it for a while, but then it started again, so I disabled the processor power management features in the BIOS.

The post didn't mention if this is a laptop or desktop, but even modern desktop CPUs have lots of power states. Worth a look.
