Internet Block
Completely cut off any program's internet access — both inbound and outbound traffic. Eliminates unwanted auto-updates, telemetry reporting, license call-homes, and any form of data leakage from your applications.
Take complete command of your Windows environment. Block any application from accessing the internet or running entirely — with zero background process, zero performance impact.
Take Full Control of Every Program on Your PC
ProgramBlocker is a powerful Windows utility designed to give you direct, no-nonsense control over which programs can access the internet and which programs can run at all — in just a few clicks, with no technical knowledge required. Whether you want to cut off a game's online connection, stop unwanted software from launching, or completely lock down a specific application, ProgramBlocker puts you in command instantly.
Unlike complex firewall configurations or group policy edits, ProgramBlocker works through a clean, intuitive interface that any user can understand. Select a program, choose your block type, and it's done — the block survives reboots, updates, and everything in between, with absolutely zero background processes running.
💡 Did you know? Many popular programs silently send telemetry data, to verify licenses, or auto-update themselves without ever asking for your permission. ProgramBlocker lets you stop all of that — permanently.
Key Features
Execution Block
Prevent any program from launching at all — it cannot start, cannot run in the background, and cannot be triggered by other software. Ideal for parental control, software lockdowns, and enterprise workstation security.
Zero Performance Impact
Once blocks are applied, ProgramBlocker does not need to remain running. There are no background services, no memory usage, and no CPU overhead. Blocks are enforced at the system level and persist indefinitely.
Fully Reversible
Every block you apply can be removed at any time with a single click. ProgramBlocker maintains a persistent, editable blocklist so you always stay in control — no permanent changes, no registry mess, no risk.
System-Level Filtering
ProgramBlocker uses Windows Firewall rules and execution policies at the system level — not simple host file tricks. This means your blocks are robust, tamper-resistant, and effective even when programs try to bypass them.
Parental Control Ready
Restrict children's access to specific games, social media apps, or any software you choose — without complicated parental control suites. Block internet access while still allowing offline use, or block execution entirely.

How ProgramBlocker Works
Unlike simple host file edits or superficial app blockers, ProgramBlocker integrates directly with Windows' own system-level filtering mechanisms to ensure that your targeted applications stay blocked — no matter what. The software maintains a clean separation between two distinct block types: Internet Block and Execution Block, giving you granular control that most tools simply don't offer.
For example, you can block a game from accessing its online servers while still allowing it to run in offline mode — great for preventing in-game purchases or online matchmaking without disabling the game entirely. Alternatively, you can lock down an application completely so it cannot run under any circumstances, which is ideal for parental control environments or shared workstations.
Every block is applied immediately upon confirmation and persists through system reboots and application updates. ProgramBlocker maintains a reliable blocklist that survives even when the blocked software attempts to update itself or reinstall. And because all enforcement is handled at the OS level, ProgramBlocker itself doesn't need to run in the background — meaning zero CPU usage, zero memory footprint, and zero performance impact once your blocks are set.
Whether you are a parent managing your children's screen time and app access, an IT administrator securing employee workstations, a developer testing network behavior, or simply a privacy-conscious individual who doesn't want applications reporting back to their servers — ProgramBlocker gives you the control you need, delivered through an interface anyone can use in under a minute.
Supported on: Windows 7, 8, 10, and 11 (32-bit and 64-bit).
