Windows 10 and 11, 64-bit. Requires a license key.
- Digitally signed updates

How it works
Quarkium reads your hardware first, so the recommendations fit your PC instead of a generic list.
Detect
CPU, GPU, RAM, motherboard and drives (SSD, NVMe, HDD) appear on the home screen, with live CPU and RAM.
Review
Recommended tweaks come pre-selected: SSD tweaks are not applied to an HDD, and a laptop gets different picks than a desktop. Nothing is applied until you confirm.
Apply and undo
Quarkium offers to create a restore point first. Once applied, registry and service tweaks can be undone from inside the program.
What Quarkium does
Optimizations
Tune Windows for your hardware and clear what weighs it down.
- Windows tweaks
- About 30 tweaks in Privacy, CPU, GPU, RAM, SSD, HDD, Network, Services, Explorer and Debloat. The ones that fit your hardware come pre-selected.
- Debloat
- Apps that ship with Windows, sorted as suggested, optional, third-party or protected. Search, filter and choose what to remove. Essential apps are locked.
- Disk cleanup
- Temporary files, Windows Update cache, DirectX shader cache, error reports, minidumps, Recycle Bin and DNS cache. The space to be freed is shown before you clean.
- Startup programs
- Turn on or off what launches with Windows. Reversible.
- Restore point
- Created before you apply changes, so you can roll Windows back.
- Free RAM
- Releases memory on demand with one click.
Quarkium Speed
A mode focused on performance, in the side menu.
- Automatic RAM cleaner
- Frees memory by itself, by usage threshold or time interval, using the rules you set.
- Game Mode
- One switch for performance: power plan, reduced visual effects, Windows Game Mode on and background recording off. It can also free RAM and close processes. Turning it off puts Windows back as it was, even if you closed Quarkium in the meantime.
- Deep clean
- Scans your drive and shows a folder tree sorted by size, so you can find what takes up space and delete it.
- Processes
- See what runs in the foreground and background and close what you don't need.
Quarkium Score
Measure the effect on your own PC.
- Score test
- Measures CPU, RAM and disk in about 10 seconds and gives a score from 0 to 1000. Compare it with your previous test to see what your optimizations changed.
- Bottleneck diagnosis
- Watches your PC for a few seconds and shows what limits performance most (disk, memory or CPU), plus weak points in your hardware.
Interface
Built for weaker and stronger PCs alike.
- Visual modes
- Light has no animations and uses minimal CPU and GPU, for low-end PCs. Physics adds transitions, particles and animations. Switch whenever you like.
- Languages
- English, Português (BR), Español.
Every change is yours to confirm and undo.
Medium-risk tweaks are never pre-selected.
Registry and service tweaks save the original value and can be undone from the interface. Quarkium also offers a restore point before you start.
Quarkium refuses to delete critical folders such as Windows, Program Files and Users, and does not close essential Windows processes.
Deleting files, closing processes and removing apps require holding the button for 3 seconds, to prevent accidental clicks.
Quarkium checks for new versions by itself and only installs updates that carry a valid digital signature.
Quarkium connects to the internet only to sign in, verify your license and check for updates.
Removing preinstalled apps. It is marked as irreversible in the program. If you need an app back, reinstall it from the Microsoft Store.
Use Quarkium Score to measure the difference on your own PC. Large Windows updates can undo some tweaks; apply them again.
