Chrome blocks fresh unsigned exe files, so the file is served from GitHub. Right-click the zip → Extract All → run NULLSUB.exe inside. One extra step, no installer, no admin. If Chrome still says "not commonly downloaded", press Keep; SmartScreen — More info → Run anyway. GitHub blocked? Use the mirror.

01 / how it works

STEP 01

run the exe

One file, no installer, no admin. It reads the uninstall registry and running processes and shows only the apps that actually exist on this machine.

STEP 02

click one icon

Each click patches exactly one app: license seal bound to your HWID, patch log, hex ticker. Nothing else is touched, nothing is activated in bulk.

STEP 03

keep it

The unlock lives in %LOCALAPPDATA%\nullsub and survives reboots. F5 walks every installed app, RESET wipes the seal and starts over.

03 / faq

Is it really free?

Yes. No account, no trial clock, no card. The unlock is written locally and stays until you press RESET. Limits are honest: a patched app behaves like a paid seat on this machine, it does not turn into a cloud plan with unlimited quota.

Does it need internet?

No. Everything happens on this PC. The exe can be started with the network cable pulled.

Chrome / SmartScreen warn me

Normal for an unsigned binary that is two days old. Chrome: Keep. SmartScreen: More info → Run anyway. There is no installer and no driver, so nothing else is asked of you.

My app is not in the list

Press RESCAN if you just installed it. Portable or web-only services are hidden on purpose — hit SHOW ALL APPS and pick the tile by hand.

Does it work after a reboot?

Yes. The seal lives in %LOCALAPPDATA%\nullsub and is restored on start.

Where do I check the version?

Bottom-right of the window, in ABOUT, and in HELP — this page ships v1.11.8.
