Lists PCI devices with their current interrupt affinity policy in Out-GridView, then pins the interrupts of the devices you select to the CPU cores you pick in a second grid (P/E-cores labeled on hybrid CPUs). Writes the documented DevicePolicy / AssignmentSetOverride registry values. Zero external dependencies. Windows PowerShell 5.1+.

Lists PCI devices, shows their MSI status in Out-GridView, and enables MSI for the devices you select. Zero external dependencies. Windows PowerShell 5.1+.

Enumerates devices whose driver is still registered but that are not currently present - the ghost entries left behind by unplugged USB sticks, headsets, dongles and old GPUs - and removes them so Device Manager reflects only hardware that is actually connected. Self-elevates via UAC. Zero external dependencies.

Turns off Game DVR (Game Bar background capture / recording) via the documented AllowGameDVR machine policy plus the per-user GameDVR values, and disables Fullscreen Optimizations globally via the GameConfigStore FSE values. A .reg undo file with the previous state of every value is written next to the script BEFORE any change. Zero external depen... More info

Shows the current state of the Windows timer stack (timer resolution, bcdedit timer tweaks, HPET, Windows 11 global resolution requests), measures real Sleep(1) precision, and applies the tweaks you select in a grid - each one opt-in, with a JSON undo file and a full BCD backup written before any change. Zero external dependencies.

This script disables CPU core parking (CPMINCORES/CPMINCORES1 = 100%) and sets Energy Performance Preference (PERFEPP/PERFEPP1 = 0) on the current power scheme. Supports Intel 12th gen+ hybrid CPUs (separate P-core/E-core settings) and traditional non-hybrid CPUs (AMD Ryzen, older Intel). Class 1 (P-core) settings that don't exist on non-hybrid CP...
