Latency and interrupts
Reads DPC and ISR timings per driver and names the one costing you frame pacing, rather than reporting a single unhelpful score.
Windows performance tuning
Tune Windows without guessing what changed.
Most optimisers apply a pile of registry edits and leave you hoping. Kurm Optimizer names every change, writes a restore point before it touches the registry, and puts it all back on request.
One account, no subscription, nothing renews. All sales final. Questions before you buy? Contact us.

What it actually changes
Every panel reports what it found and what it will do before it does it.
Reversible registry work
A restore point is written before any registry value changes, and every tweak the app applies can be put back from inside the app.
Clocks and voltages
Overclock targets on the Maximum tier, opt-in and never applied silently. Hardware risk is stated plainly before you can enable it.
Privacy and cleanup
Startup entries, scheduled tasks, telemetry services and disk clutter, each listed with what it is before you decide to remove it.

Questions people actually ask
What happens if I change my hardware?
Nothing changes. Your plan belongs to your Kurm account, not to the hardware, so sign in to Kurm Optimizer again and it is there.
Does the plan check need internet?
Yes, for paid plans. The app checks your plan with your account. If the connection drops mid-session, your plan stays on for 30 minutes after the last good check; offline at launch, only the free panels open.
Can I use my plan on another PC?
Yes. Sign in there with the same account. One desktop session can be active at a time, so signing in on the new PC signs the old one out. Sharing an account is not allowed.

Free download
Ten panels are free forever with a free Kurm account. Install it, look around, and buy a plan only if you want the rest.
Kurm Optimizer for Windows
Windows 10 and 11, 64-bit. No installer — extract and run.
You need a free Kurm account to download.
Extract the whole folder before running it — the .exe needs the .dll files beside it. Windows asks for administrator permission, which is genuinely required to read hardware sensors and change system settings. Full install notes, requirements and checksum.
