How to Optimize Windows 11 with Win11Debloat: Safely Remove Bloatware and Improve PC Performance (2026 Guide)

1. Introduction

Your Windows 11 PC should feel fast the moment you turn it on. Instead, many users are met with pre-installed apps, promotional content, Widgets, background services, and software they never asked for. A fresh Windows installation should feel clean and responsive, but it often feels cluttered before you even install your first application.

If you’ve ever wondered why your new computer uses several gigabytes of RAM while sitting idle, why unnecessary apps keep appearing in the Start menu, or why your system seems busy even when you’re doing nothing, you’re not imagining it. Many of these features are enabled by default, and while some users may find them useful, others simply want a cleaner, faster, and more responsive Windows 11 experience.

The good news is that you don’t have to reinstall Windows or spend hours changing dozens of settings manually. With the right approach—and the right tools—you can remove unnecessary software, reduce background activity, improve responsiveness, and make your PC work the way you want it to.

But here’s something many articles don’t tell you: debloating Windows isn’t about removing everything. It’s about removing the right things. An aggressive cleanup can break useful features or create problems after future Windows updates. A smart cleanup improves performance while keeping your system stable, secure, and easy to maintain.

Knowing the difference is what separates a quick fix from a long-term solution.

Whether you’re a student, gamer, professional, developer, content creator, business user, or simply someone who wants to get the most from a new or existing PC, this guide will help you understand what can safely be removed, what should stay, and how to optimize Windows 11 without unnecessary risks.

Our team has more than 20 years of experience researching computer hardware, Windows software, and performance optimization. Every recommendation in this guide is based on technical analysis, documented features, community feedback, and practical usability rather than marketing claims. Our goal is simple: help you choose the best solution for your needs, whether your priority is maximum performance, better privacy, improved reliability, or the best value for your money.

By the end of this guide, you’ll know exactly what Win11Debloat does, whether it’s safe, how much performance you can realistically gain, and how to optimize Windows 11 without sacrificing stability or future compatibility.

2. Quick Answer

Win11Debloat is a lightweight, open-source PowerShell script that automates the removal of pre-installed bloatware and disables intrusive features in Windows 11.

• Is it safe? Yes, if you use the “Default” mode and create a system restore point first.

3. Why Windows Feels Bloated

Windows includes Microsoft services, recommended apps, cloud features, and productivity tools that not every user wants or needs.

• Background apps: Things like Teams and OneDrive start automatically, even if you never use them.
• Startup services: OEM software from brands like Dell or HP often adds unnecessary “support” tools that lag your boot time.
• Telemetry: Windows regularly sends diagnostic and telemetry data to Microsoft to help improve system reliability and Depending on your privacy settings, this activity may use background system resources.
• Ads & Widgets: The taskbar is cluttered with news feeds and “suggested” content that is basically just advertising.
• Copilot & AI: New AI features are baked into the OS, consuming resources even if you prefer traditional workflows.

4. What Win11Debloat Actually Changes

Win11Debloat removes selected pre-installed apps, changes Windows settings, and disables certain optional services based on the options you choose.

Removes:

• Consumer apps: Pre-installed applications like Candy Crush, Disney+, and Spotify.
• OEM apps: Brand-specific bloatware that clutters new laptops.
• Gaming extras: Non-essential Xbox overlays (you can choose to keep the core gaming features).
• Recommended apps: Those annoying “trial” versions of software.

Disables:

• Telemetry: Reduces Windows telemetry by disabling many optional diagnostic services and background data collection features.
• Ads & Suggestions: Cleans up the Start menu and lock screen.
• Widgets: Removes the news feed from the taskbar.

Leaves Untouched:

• Core Windows components: Essential services like Windows Update and Microsoft Defender stay active.
• Drivers: Hardware drivers remain untouched, so your devices should continue working normally unless they rely on software you choose to remove.

5. Default Mode vs. Custom Mode

When you run the script, you have a choice. Here is our take on which one you should pick:

6. Step-by-Step Installation Guide

Don’t just double-click and hope for the best. Follow this workflow to stay safe.

Before You Start:

1. Create a restore point: This is non-negotiable. If something breaks, this is your “undo” button.
2. Backup files: It’s rare for a debloater to touch personal files, but better safe than sorry.
3. Verify script source: Only download from the official GitHub to avoid malware.

Installation:

1. Download from GitHub: Grab the latest release ZIP and extract it.
2. Run PowerShell as Admin: Right-click the bat file or open PowerShell and navigate to the folder.
3. Execute: If using the “Quick Method,” paste the command from the GitHub readme into your terminal.
4. Choose Mode: We recommend Custom Mode so you can keep apps you actually use (like Calculator).

Post-installation checklist:

• Reboot your computer immediately.
• Check if your printer and Wi-Fi still work (they should).
• Open the Microsoft Store to see if it still functions.

7.  Typical Performance Improvements Reported by Users

These figures are representative examples compiled from community feedback and publicly shared test results. Individual results will vary depending on hardware, Windows build, installed applications, and system configuration.

Why improvements vary: On a $3,000 gaming PC, you might not “feel” the speed. On an older laptop with 8GB of RAM, these optimizations can noticeably improve responsiveness. On newer, high-end PCs, the difference may be less noticeable because the hardware already has plenty of available resources.

8. Best Settings for Different Users

• Gamers: Disable the Game Bar and all Keep “Graphics Performance” tweaks.
• Office Users: If you actively use OneDrive, keep it enabled along with Teams. Otherwise, you can safely remove or disable OneDrive and remove the News and Interests widgets to reduce background activity.
• Developers: Disable all AI features and telemetry; keep WSL and Sandbox
• Students: Remove gaming bloat but keep the Microsoft Store and Photos
• Older Laptops: Older laptops with limited hardware can benefit from more aggressive Disable transparency effects and unnecessary startup apps, but only remove features you know you won’t use.
• Privacy-focused: Disable “Find My Device,” location services, and all

9. Common Mistakes to Avoid

• Removing the Microsoft Store: Reinstalling it later can require additional manual Unless you’re sure you won’t need it, it’s usually best to leave it installed.
• Skipping the Restore Point: We can’t stress this enough.
• Using Unknown Scripts: Stick to Win11Debloat. Don’t download “speed up PC” scripts from random forums.
• Disabling required services: If you use a VPN or specific work software, check if the script disables their dependencies.

10. Can Windows Updates Undo Debloating?

Major Windows feature updates may restore certain default settings and reinstall some Microsoft apps that were previously removed or disabled.

• Cumulative Updates: These are usually safe and won’t bring back
• Feature Updates: Major version jumps (like moving to a new yearly build) will often reinstall “suggested” apps and re-enable telemetry.
• Maintenance: We recommend reapplying your favorite tweaks once every few months or after a major update.

11. How to Undo Every Change

Regret is a thing. Here’s how to go back:

1. Restore Point: Use the one you made at the It’s the fastest way.
2. Script Rollback: The script folder usually contains an “Undo” folder with registry files to revert changes.
3. Reinstall Apps: If you deleted an app you need, just find it on the Microsoft Store and hit “Install.”
