Windows 11 Settings to Change Immediately

The most important Windows 11 settings to change immediately are the ones that affect your privacy, security, and system performance. You should turn off targeted ads and diagnostic data, disable startup apps, and adjust your power and update settings within the first hour of setup.

Why These Settings Matter

Windows 11 ships with a default configuration designed to work for the broadest possible audience, not for you specifically. That means it comes with telemetry enabled, background apps running, and visual effects that can slow down older hardware. Changing a handful of settings right after installation reduces the amount of data Microsoft collects about your habits, stops unnecessary programs from eating your RAM, and can extend your laptop’s battery life. None of these changes require third-party tools or registry hacks; they are all built into the operating system’s Settings app.

Privacy Settings to Turn Off First

Microsoft collects diagnostic data to improve Windows, but you can limit what it gathers. The most impactful privacy settings are found under Settings > Privacy & security. Here is what to change:

• Diagnostic data: Under Diagnostics & feedback, change “Send optional diagnostic data” to Off. This stops Microsoft from collecting details about your browsing, app usage, and typing.
• Tailored experiences: Turn off “Let Microsoft use your diagnostic data to offer you personalized ads, tips, and recommendations.” This is the setting that makes ads appear inside the Start menu and Settings app.
• Advertising ID: Under General, turn off “Let apps show me personalized ads by using my advertising ID.” This prevents apps from tracking you for ad targeting.
• Activity history: Under Activity history, uncheck “Store my activity history on this device” and “Send my activity history to Microsoft.” This stops Windows from keeping a timeline of the files and apps you use.
• Find my device: Under Find my device, turn it off unless you genuinely need to track a stolen laptop. It periodically sends your device’s location to Microsoft.

These changes do not break any core functionality. You will still receive security updates and can use the Microsoft Store normally.

Startup Apps and Background Permissions

Many programs install themselves to run at startup, which slows down boot time and consumes memory. To manage this, open Settings > Apps > Startup. You will see a list of apps with a toggle next to each. Disable anything you do not need immediately after logging in, such as Spotify, Discord, or manufacturer updater tools. Windows itself will still start correctly.

Next, check background app permissions. Go to Settings > Apps > Installed apps, click the three-dot menu on an app, and choose Advanced options. Under “Background app permissions,” select Never for apps you do not need to run in the background, like Mail or Photos. This prevents them from consuming CPU and network bandwidth when you are not using them.

Power and Battery Settings for Performance

Windows 11 defaults to a “Balanced” power mode, which is fine for most users, but you can squeeze more performance or battery life depending on your needs. Go to Settings > System > Power & battery.

• Power mode: If you are on a desktop, set it to Best performance. On a laptop, choose Best power efficiency to extend battery life, or keep it on Balanced if you want a compromise.
• Screen and sleep: Set your screen to turn off after 5-10 minutes of inactivity and your PC to sleep after 15-30 minutes. This saves energy and reduces wear on the display.
• Battery saver: On laptops, set battery saver to turn on automatically at 20% or 30% rather than the default 20%. This reduces background activity and dims the screen to stretch the last portion of your charge.

For gaming or heavy video editing, also check Settings > System > Display > Graphics and assign specific apps to “High performance” using your dedicated GPU if you have one.

Update and Delivery Optimization Settings

Windows Update is essential for security, but some of its defaults can waste bandwidth. Go to Settings > Windows Update > Advanced options > Delivery Optimization. By default, Windows may upload updates to other PCs on the internet using peer-to-peer sharing. Change the toggle to Off or restrict it to “Devices on my local network” only. This prevents your internet connection from being used to distribute updates to strangers.

Also, under Windows Update > Advanced options, set “Active hours” to the time you typically use your PC. This tells Windows not to restart automatically during that window, which prevents the frustrating situation of losing unsaved work to a reboot.

Visual Effects and Gaming Optimizations

Windows 11 includes animations, shadows, and transparency effects that look nice but consume system resources. To disable them, open Settings > Accessibility > Visual effects and turn off “Animation effects” and “Transparency effects.” This makes the interface snappier on older hardware and can slightly improve frame rates in games that run in windowed mode.

For gamers, also go to Settings > Gaming > Game Mode and ensure it is On. Game Mode prioritizes your game’s CPU and GPU usage and suppresses Windows Update and notifications while you play. Under Settings > Gaming > Captures, turn off background recording if you do not use the Xbox Game Bar to record clips; this saves disk space and reduces GPU load.

Storage Sense and Temporary Files

Windows 11 accumulates temporary files, old updates, and recycle bin contents. Enable Storage Sense to automate cleanup. Go to Settings > System > Storage and turn on “Storage Sense.” Click into it and set it to run weekly, delete temporary files that apps are not using, and empty the recycle bin after 30 days. This keeps your system drive from filling up with junk that can slow down the entire PC.

You can also manually clean up now by clicking “Temporary files” in the same screen and selecting everything you want to remove, such as Windows Update Cleanup and Thumbnails.

Common Mistakes and Misconceptions

A frequent misconception is that disabling all privacy settings will break Windows. It will not. You will still get security updates, and your apps will still work. The only thing you lose is personalized ads and some telemetry.

Another mistake is disabling startup apps that are actually needed, such as your antivirus or a driver updater. If you are unsure what an app does, leave it enabled. You can always disable it later if you notice it using resources.

Finally, many users turn off Windows Update entirely to avoid restarts. This is dangerous because security patches protect against ransomware and exploits. Instead of disabling updates, set active hours and let updates install during your downtime.

Frequently Asked Questions

Will changing these settings void my warranty?
No. All the settings described here are built into Windows 11 and are meant to be user-configurable. They do not affect your hardware warranty.

Do I need to restart after changing these settings?
Most changes take effect immediately. Startup app changes apply the next time you log in, and power settings apply instantly. A restart is only needed if Windows prompts you for it.

Can I undo these changes later?
Yes, every setting can be reverted by going back to the same screen and toggling it back to the original value.

Will turning off diagnostic data stop Windows Defender updates?
No. Security intelligence updates for Windows Defender are downloaded through Windows Update and are not affected by the diagnostic data setting.

Why does Windows 11 still show ads after I turned off tailored experiences?
Some ads in Windows 11, like “Tips and suggestions” in the Start menu, are controlled by a separate setting. Go to Settings > Personalization > Start and turn off “Show suggestions for tips, shortcuts, and new apps.”

Does disabling background apps save battery?
Yes, significantly. Apps that run in the background can wake your CPU, use Wi-Fi, and refresh data. Setting them to “Never” prevents this and can add 30-60 minutes of battery life on a typical laptop.
