This forces the CPU to stay at maximum power at all times. On a desktop that mostly means extra heat and wasted electricity, but it can destabilize power delivery on lower-quality PSUs, raise temperatures enough to trigger thermal throttling (making the PC slower, not faster), and on laptops it drains the battery very quickly.

This turns off a Windows display-composition layer. On some driver combinations it fixes flicker, but on others it causes exactly those symptoms: desktop flickering, stuttering video playback, broken HDR brightness, or glitchy window rendering. If your display starts misbehaving, revert this first.

Memory integrity is a real Windows security feature: it blocks many kernel-level malware techniques. Disabling it leaves your kernel less protected, and some anti-cheat systems (Vanguard for Valorant, several others) refuse to run without it. Only do this on a machine used for gaming where you accept the security tradeoff.

This pins the Windows kernel into physical RAM so it can never be paged out. On a PC with plenty of RAM that is fine, but on a machine with 8 GB or less it shrinks the memory available to your apps and can cause more out-of-memory errors, freezes, or crashes under load. A restart is required for the change to take effect.

Hibernation lets you close the lid and resume exactly where you were after days of sleep. If you rely on hibernate or Fast Startup, this removes both. Laptop users who hibernate overnight should leave this off.

With flushing off, data sitting in the drive cache is lost if power is cut mid-write - an outage or pulling the plug can corrupt whatever was being written at that moment. Laptops on battery are partly protected; desktops on a surge-only strip are not. Enable only with a UPS.

Policy-based QoS, DSCP traffic marking and third-party traffic shapers stop working, and the change (or the revert) only takes effect after a restart. Everyday browsing, downloads and gaming are unaffected. Fully reversible.

Turning this off breaks apps that rely on knowing where you are: Maps, Weather auto-detect, Find My Device and time-zone auto-set during travel. Enable it again if any of those matter to you.

If you regularly move files between drives and rely on .lnk shortcuts still resolving, re-enable this - those links will stop following the moved target.

Phone Link's notification sync, Nearby Sharing and cross-device resume stop working if you ever want them. The service may be restarted by Windows on some builds; if it reappears, revert this tweak.

Disabling DPS also disables automatic troubleshooting wizards (network adapter fix, audio troubleshooter) and some 'recommended troubleshooting' notifications. Windows Update, including driver delivery, keeps working normally.
