Real PC optimization.
Zero BS.
Astrix is a Windows 11 optimizer with 80 genuinely effective tweaks — every switch maps to a documented, measurable system change. Clean junk, cut latency, boost FPS, kill telemetry. One 400 KB app, no installer bloat.
Everything it actually does
No mystery "boosts." Each capability is a transparent switch you control, and you can see exactly what it changes.
Reclaim real space
Clears temp files, Windows Update cache, crash dumps, thumbnails and the Recycle Bin — and shows a live estimate of how much it'll free before you run.
Make Windows snappy
Ultimate Performance power plan, foreground priority, zero menu delay, killed startup lag, USB suspend off — the tweaks power users apply by hand.
Squeeze out FPS
Game Mode, hardware-accelerated GPU scheduling, Game DVR off, GPU priority for games, exclusive fullscreen. Less overhead, more frames.
Cut network latency
Disable network throttling, max responsiveness, TCP auto-tuning, Nagle off for gaming, plus one-click Winsock / TCP-IP repair.
Shut down tracking
Telemetry off, DiagTrack disabled, advertising ID, activity history, Bing-in-Start and "suggested" app installs — all gone.
Safe by default
Optional restore point before every run, a confirm prompt, behaviour-changing tweaks off by default, and a full activity log of every action.
Real, measurable gains
Representative before/after results on a mid-range gaming PC (Ryzen 5 5600 + RTX 4060). Your numbers depend on your hardware and how cluttered Windows already is — Astrix won't promise miracles.
Idle RAM usage
Boot time
Numbers are representative, not guarantees — that's the honest part. Run the same test before and after on your own PC to see your real gain.
Start to finish in under a minute
Open Astrix, hit Run, watch the cleanup and the score climb. Prefer hands-on? The in-browser demo is live.

Five steps, fully in your control
No black box. You see — and approve — every stage.
Tuned for the games you play
Game Mode, GPU scheduling, Game DVR off, raw mouse input and RAM freeing target real frame-rate and input-lag wins. Results vary by hardware & settings.
Runs on your PC
Astrix works on any 64-bit Windows 10 or 11 machine — Intel or AMD, NVIDIA or otherwise, SSD or HDD.

5 tweaksHonest by design
"Optimizers" that promise thousands of tweaks are padding the number with junk — placebo registry edits, fake RAM "boosters," things that do nothing or actively hurt. Astrix refuses to play that game.
- Every tweak is real, documented, and reversible
- You see the exact change each switch makes
- The "reclaimable space" number comes from a real disk scan — it can say 0 MB, because that's the truth
- No bundled toolbars, no upsells, no telemetry of our own
- One small signed executable you can read the behaviour of
There are maybe 40–60 tweaks that genuinely help a modern Windows 11 machine. Astrix ships those — and nothing else.
Astrix vs. typical "optimizers"
Most PC cleaners are bloated, subscription-based, and padded with tweaks that do nothing. Here's the honest comparison.

Astrix needs administrator rights to apply system tweaks, so Windows will show a UAC prompt. Because it edits the registry and services, SmartScreen or Defender may warn on first run — that's a heuristic false positive for this class of tool, not malware. Click More info → Run anyway.
Install & use in 4 steps
No setup wizard — Astrix is a single portable .exe.
Download
Grab Astrix.exe above — one 400 KB file, no installer, nothing bundled.
Run as admin
Double-click it and approve the UAC prompt (Astrix needs admin to change system settings). If SmartScreen warns, click More info → Run anyway.
Pick & run
Toggle what you want (or Select all), keep Create a restore point on, and hit RUN OPTIMIZATIONS.
Activate Pro
Bought Plus or Pro? Open Settings → Astrix Plus / Pro, paste your emailed key, hit Activate — it unlocks instantly.
Tip: tweaks tagged REBOOT apply after a restart. Use Settings → Check for updates to stay current, and Game Boost (Pro) to free RAM before gaming.

Estimate your gains
A rough guide based on how much background overhead Astrix typically clears. An estimate only — real results depend on your exact setup.
Lower-end and cluttered systems gain the most. Astrix frees RAM, cuts background processes and prioritises your game — it can't add hardware you don't have.

Built to be trusted
Optimizers have a bad reputation. Here's exactly why Astrix isn't one of the bad ones.
Restore point first
Astrix can snapshot Windows with System Restore before every run, so any change can be rolled back.
Every tweak reversible
Each switch maps to a documented Windows setting you can flip back. Removed apps reinstall from the Store.
No telemetry
No accounts, no tracking, no analytics. The app makes no network calls of its own except the update check.
No crypto mining
Astrix never uses your CPU/GPU for anything but reading live stats. It frees resources, it doesn't steal them.
No ads, no subscriptions
One-time purchase. No banners, no upsell nags, no recurring billing.
No bundled software
One ~400 KB .exe. No toolbars, no "partner offers", no installer that sneaks in extras.
Heads-up: because Astrix self-elevates and edits the registry/services, Windows SmartScreen or Defender may show a heuristic warning on first run. That's the same false positive every tool in this class gets — choose More info → Run anyway.
Questions, answered straight
Is Astrix safe?
Yes. Every tweak is documented and reversible, behaviour-changing ones are off by default, and Astrix can take a System Restore point before each run. It also logs every action so you know exactly what happened.
Why does Windows say "unknown publisher" or flag it?
Astrix self-elevates and edits system settings, which matches the pattern security tools watch for — so SmartScreen/Defender can warn even though it's clean. A signature only removes that on machines that trust the certificate. Choose "More info → Run anyway".
Will it really speed up my PC?
It applies the same legitimate tweaks power users do by hand — clearing junk, cutting background overhead, prioritising the foreground/games. Gains depend on your hardware and how cluttered Windows already is. No optimizer can perform miracles, and Astrix won't pretend to.
Does it collect any data?
No. Astrix has no telemetry, no accounts, no network calls of its own. It runs entirely on your machine.
How do I undo a change?
Restore from the point Astrix created, or flip the relevant Windows setting back. Tweaks that need a reboot are clearly tagged in the app. Removed apps can be reinstalled from the Microsoft Store.
How do I get help or support?
Join our Discord — it's the fastest way to get support, report a bug, or request a feature. There's a Support button inside the app too (Settings → Get help & support).
