How to block games on Windows in 2026

Games are engineered to keep you playing. Launchers auto-update, friends are always online, and titles like Roblox, Fortnite and Minecraft have no real "end" — so a quick session quietly becomes three hours. If that's wrecking a child's study time or your own deep work, blocking games at the source is the fix. This 2026 guide walks through every practical method on Windows, where each one falls short, and how to make blocking actually stick.

Why block games on Windows?

There are three reasons this keeps coming up, and they apply to adults and kids alike:

• Study and focus. A game is one Alt-Tab away while you're meant to be revising or working. Removing the temptation entirely is far more effective than relying on willpower — the most reliable way to not play is to make the game refuse to open.
• Children's screen time. Open-ended, highly engaging games crowd out sleep, homework and time outdoors. Clear, enforced limits ("school nights are game-free; an hour at weekends") work better than nagging.
• Productivity at work. On a shared or work PC, a quietly installed game or a browser game tab can swallow a surprising amount of the day. Blocking it keeps the machine for what it's for.

The built-in ways to block games — and their limits

Windows gives you a few levers out of the box. They're free and worth knowing, but each has a gap that a determined player (or a curious kid) can slip through.

1. Microsoft Family Safety

If everyone uses Microsoft accounts, Family Safety can set screen-time limits and block specific apps and games on a child's account. It's a reasonable starting point. The catch: it leans on the child being signed into their Microsoft account and using Microsoft Edge for web filtering. A local Windows account, a second browser, or a portable game that doesn't need installation can sidestep it, and the controls are coarse — you don't get fine per-app daily budgets that differ by weekday.

2. The hosts file or router-level blocks

You can add game and store domains (for example store.steampowered.com or roblox.com) to the Windows hosts file, or block them on your router. This stops some downloads and browser games. But it does nothing about games already installed on the PC, it's trivial to undo if the user has admin rights, and maintaining a domain list by hand is a losing battle as games shift servers.

3. Standard user accounts and uninstalling

Making the child a standard (non-admin) user stops new installs, and you can uninstall existing games. It helps, but it's all-or-nothing: there's no "an hour a day" middle ground, browser games still load, and any game that runs without installation — or a reinstall during a moment of admin access — puts you back to square one.

How to block games with Kaizen Focus (step by step)

1. Download and install Kaizen Focus on the Windows PC using the button below — the free version installs in a couple of minutes and starts with Windows.
2. Set an admin PIN. Pick a 4-digit PIN so only you can change the rules; a child's standard account can't undo them.
3. Block the game apps and launchers. Add Steam, the Epic Games Launcher, Roblox, Minecraft, the Riot Client and any other installed game to the app blocklist. Focus closes them during restricted hours.
4. Block the game stores and browser games. Add domains like store.steampowered.com, epicgames.com, roblox.com and poki.com so new downloads and web games are blocked across every browser.
5. Add limits or downtime (optional). Prefer some play? On Pro, set a daily limit per game with weekday-specific values, or schedule downtime over homework hours and after bedtime.
