Performance Tweaks

Apply tried-and-true Windows settings that trim startup time, reduce background noise, and make the interface feel snappier.

What it does

Windows ships with settings that favor new PCs and data-collection features that help Microsoft more than they help you. Performance Tweaks offers a curated list of reversible changes — the kind you'd read about in "speed up Windows" articles but packaged into safe, one-click toggles.

When you open the page, TuneBit scans your system and marks each tweak with its current state: Applied, Default, or Not applicable.

What kinds of tweaks are included

Startup & Boot

Disable unnecessary startup programs, trim boot delay values, and enable Fast Boot where appropriate.

Visual Effects

Turn off animations, transparency, and shadow effects on slower PCs. The interface becomes less pretty but noticeably faster — especially on systems without a discrete graphics card.

Background Tasks

Stop telemetry, advertising ID collection, app prelaunching, and background apps running with no visible window.

Indexing & Search

Reduce the indexing scope to only the folders you actually search, which keeps searchindexer.exe from chewing disk in the background.

Power & Responsiveness

Switch to the High Performance power plan on desktops, and set the CPU minimum state to keep cores responsive rather than throttled.

Network

Tweak TCP settings that help on high-latency connections, and disable legacy protocols (like LLMNR) that aren't used on a home network.

How to use it

Go to Optimize → Performance Tweaks. A scan runs automatically.
Skim the list. Each tweak has a short description and a status chip.
Check the boxes for any you'd like to enable. (The ones labeled "Applied" are already on.)
Click Optimize Selected. A log on the right shows what was changed.
If you need to undo, click Restore Defaults and select the tweaks you want to revert.

Conservative starter set: Disable Telemetry, Disable Advertising ID, Disable Background Apps, Trim Visual Effects. Those four are almost always safe and give most of the perceived speed improvement.

Every tweak is reversible. TuneBit records the previous values so you can click Restore Defaults at any time. If a tweak breaks something unexpected (for example, a game that relied on background audio), roll it back from this page.
