Tweaks are small, targeted changes to Windows settings, registry keys, or system services that modify how your PC behaves. In Sparkle, each tweak is a self-contained PowerShell script that applies a specific optimization or customization.

​
How tweaks work

Every tweak is built from three files:
FilePurpose
meta.jsonDefines the tweak’s name, description, category, risk level, and other properties
apply.ps1Contains the PowerShell commands that make the change
unapply.ps1Reverses the change (present only for reversible tweaks)
When you toggle a tweak on, Sparkle runs apply.ps1. When you toggle it off, it runs unapply.ps1.
Some tweaks don’t have an unapply.ps1. These show an Apply button instead of a toggle, because the change cannot be automatically reversed.

​
Toggle vs. Apply button

Sparkle uses two controls depending on whether a tweak is reversible:
  • Toggle — The tweak has both apply.ps1 and unapply.ps1. You can turn it on and off at any time. The toggle reflects the current applied state.
  • Apply button — The tweak has only apply.ps1. Clicking Apply runs the script once. There is no automatic way to undo the change.
Some tweaks show a confirmation dialog before running. The modal displays the tweak name and a plain-language explanation of what will change. You must confirm before the script executes. This applies to both toggles and Apply buttons when the tweak’s modal property is set.

​
Categories

Tweaks are grouped into categories so you can quickly find what you need:

General

Broad system tweaks and common settings.

Appearance

Visual changes like dark mode, taskbar layout, and clock format.

Performance

System optimizations that improve speed and responsiveness.

Privacy

Disabling telemetry, tracking, and data collection.

Gaming

Optimizations for FPS, game services, and GPU settings.

Network

TCP/IP tuning, DNS, and network latency improvements.

GPU

Graphics driver and hardware-accelerated scheduling settings.

​
Risk levels

Every tweak has a risk level so you know what to expect before applying it.
RiskMeaning
SafeLow risk. These changes are unlikely to cause problems. Most tweaks fall into this category.
CautionMay affect system behavior or certain apps. Review the tweak description before applying.
RiskyCan significantly change system behavior. Apply with care and create a restore point first.
Risk levels are displayed as badges on each tweak card. Hovering over the badge shows a tooltip.
Risk level indicators require Sparkle 2.16.0 or later.

​
Searching and filtering tweaks

The Tweaks page provides two ways to narrow down the list:
  • Search bar — Type any part of a tweak’s name or description to filter results in real time. The counter in the top right shows how many tweaks match.
  • Category buttons — Click a category pill to show only tweaks in that group. Select All to clear the filter.
You can combine search and category filters at the same time. The Apply Recommended Tweaks button opens a modal that lists a balanced set of tweaks suitable for everyday use. You can deselect individual items before confirming. Sparkle applies each selected tweak in sequence and shows a progress notification for each one.
Look for the star icon on tweak cards — it marks tweaks that are generally safe and beneficial for most users.

​
Compatibility checks

Sparkle checks your system hardware before showing controls. If a tweak requires hardware you don’t have (for example, a dedicated GPU or an NVIDIA card), the toggle or button is disabled and a tooltip explains why.
