30FPS performance when running Unchecky Service

Windows 10 Home (1607 Anniversary Update) on Skylake hardware.

When the Unchecky service is running, my Counterstrike GO and DOTA 2 games will max out at 30fps. Suspending the service causes the performance to bounce back up to 140fps as expected.

17 / 88 computers tested have this issue, all with identical hardware and software.
