Out of the box, Windows 10 and 11 Pro come loaded with pre-installed apps and background tracking services you probably never asked for. This bloatware—ranging from promotional games to unwanted manufacturer utilities—eats up your disk space, drains battery life, and bogs down your CPU.
Telemetry is the other half of the problem. By default, Windows constantly monitors your activity and sends usage data back to Microsoft. If you want a fast, private PC, learning how to debloat Windows 11 or debloat Windows 10 is the single best optimization you can perform.
Here is how to reclaim your system resources step-by-step.
Step 1: Manual Tweaks for Immediate Speed
Before diving into advanced tools, you can manually remove Windows bloatware and stop major resource hogs directly from your system settings.
- Kill unnecessary startup apps: Right-click your Taskbar and open Task Manager. Click the Startup tab (the speedometer icon in Windows 11). Right-click and Disable anything you don’t absolutely need running the second your PC turns on, like Spotify, Skype, or automatic updaters.
- Shut down background apps: In Windows Settings, navigate to Apps > Installed Apps. If you see promotional apps you never use, click the three dots and hit Uninstall. For apps you want to keep but don’t need running constantly, go to their Advanced options and toggle off the background permissions.
- Lock down privacy settings: Go to Settings > Privacy & Security. Turn off location tracking, diagnostic data sharing, and tailored experiences. This stops Microsoft from constantly pinging their servers with your activity and frees up network bandwidth.
Step 2: Run a Windows Debloat Script for Deep Cleaning
Clicking through menus takes time and only scratches the surface. If you want to thoroughly strip out deep-rooted telemetry, forced Microsoft apps, and hidden tracking services in one go, a Windows debloat script is your best tool.
- Find a trusted script: Because these scripts interact deep within the operating system, you must use community-vetted tools. You can find reliable, regularly updated scripts hosted on platforms like mmangla.com, which curates safe utility tools specifically for system optimization.
- Run PowerShell as Administrator: Click the Start menu, type
PowerShell, right-click the top result, and select Run as administrator. - Execute the code: Paste your chosen script command into the blue window and hit Enter. Modern scripts will often open a clean, graphical menu where you can simply click a single button to remove bloatware or disable telemetry without having to write any code yourself.
Step 3: Keep Your System Clean Long-Term
Microsoft has a bad habit of sneaking bloatware and telemetry trackers back into your system during major Windows updates. A one-time cleanup is great, but long-term maintenance keeps your PC fast.
- Check after major updates: Every time Windows forces a large feature update, check your app list. If a new promotional app magically reappears, uninstall it immediately.
- Rerun your scripts: Keep your preferred debloat script handy. Running it every few months ensures any new background services Microsoft introduced are quickly disabled.
- Create restore points: Before running any optimization scripts, always type “Create a restore point” in the Start menu and save your current configuration. If a future update conflicts with your optimized setup, you can easily roll your PC back to a stable, clutter-free state.
