8 Hidden Windows 11 Settings That Are Slowing Down Your PC
Windows 11 usually feels fast and responsive right after installation. However, after months of updates, newly installed applications, startup programs, background services, visual effects, and telemetry features gradually build up. As a result, many PCs become noticeably slower, applications take longer to open, and the desktop may feel less responsive—even on relatively modern hardware.
Fortunately, you don't need to buy a faster processor or install more RAM to improve everyday performance. Windows 11 includes several built-in settings that can reduce unnecessary background activity, lower resource usage, and make your computer feel much more responsive. In this guide, we'll look at eight hidden settings that are worth checking if you want to get the most out of your PC.

Why Windows 11 Gets Slower Over Time
When you first install Windows 11, everything feels fast, clean, and responsive. But after a few weeks or months of regular use, the system often starts to feel heavier. Apps open more slowly, the Start menu hesitates, and sometimes the fan spins up even when you're barely doing anything. It’s a familiar story for most users.
The reason is simple: Windows 11 ships with background services, visual effects, telemetry, and automated features that run constantly—many of which offer little benefit to the average user. These default settings are designed to support Microsoft's ecosystem rather than maximize performance on every PC.
The good news? Almost all of these slowdowns can be reversed. Below you'll find eight practical settings you can adjust right now—without installing any third-party tools—that can noticeably improve your PC's performance in 2026.
⚙️ 1. Disable Visual Effects & Animations
Windows 11 includes smooth animations, shadows, transparency effects, and fade transitions. They look great, but each of them consumes CPU and GPU resources. On older or mid-range systems, these visual effects can noticeably reduce interface responsiveness.
To disable them, right-click the Start button and select System. Then open Advanced system settings → Performance → Settings. Select "Adjust for best performance" to disable all visual effects at once, or manually uncheck options such as "Animate windows when minimizing and maximizing" and "Fade or slide menus into view."
Most users will barely notice the visual difference, but the performance improvement can be immediate, especially on laptops with integrated graphics.
Tip: Keep "Smooth edges of screen fonts" enabled if text appears too sharp or pixelated after disabling the other visual effects.
🚀 2. Turn Off Background Apps
Many apps you rarely use continue running quietly in the background, consuming RAM and occasionally waking up your CPU. Windows 11 allows most apps to run in the background by default, and most users are surprised by how many apps are allowed to do so.
To control this, go to Settings → Apps → Installed apps, click the three-dot menu next to any app, and choose Advanced options. Under "Background apps permissions," change the setting from Always to Never for apps that don't need background activity. Good candidates include news apps, weather widgets, Xbox components, and Microsoft Store apps you rarely use.
If you want a more aggressive system-wide approach, go to Settings → System → Power & battery → Battery saver and enable it. Battery Saver automatically reduces background activity and can improve responsiveness, especially on laptops.
🔋 3. Switch to High Performance Power Plan
This is one of the easiest and most effective performance tweaks you can make—especially on desktop PCs or laptops that remain plugged in most of the time. By default, Windows 11 uses the Balanced power plan, which prioritizes power efficiency over maximum CPU performance. That's great for battery life, but not always for speed.
To change the power plan, open the Start menu and search for Control Panel. Then go to Hardware and Sound → Power Options and select High performance. If you don't see it, click "Show additional plans" to reveal the option.
On desktop PCs, High Performance is usually the best choice with virtually no drawbacks. On laptops, it's best used while plugged in, then switched back to Balanced when running on battery to extend battery life.
Note for modern Intel and AMD processors: Windows also includes an Ultimate Performance power plan that can be enabled through PowerShell. Most users won't need it, but for demanding workloads such as video editing, gaming, 3D rendering, or software development, it can deliver slightly better responsiveness by reducing power management latency.
📡 4. Disable Telemetry & Diagnostic Data
Windows 11 collects diagnostic and usage data in the background to help Microsoft improve the operating system. Services such as Connected User Experiences and Telemetry (DiagTrack) periodically gather system information and transmit it over the network. On older hardware or HDD-based systems, this background activity can occasionally contribute to brief performance slowdowns.
You can reduce this activity by going to Settings → Privacy & security → Diagnostics & feedback and setting Diagnostic data to Required only. Then disable Improve inking & typing and Tailored experiences.
For an even more aggressive optimization, you can disable the Connected User Experiences and Telemetry service. Open Services from the Start menu, locate the service, and change its Startup type to Disabled. For most home users, this won't affect Windows Update or core Windows functionality.
🖥️ 5. Manage Startup Programs
Every application that launches automatically at startup increases boot time and immediately consumes system memory. Many programs—especially those installed through bundled installers or the Microsoft Store—automatically add themselves to the startup list without asking.
Open Task Manager (Ctrl + Shift + Esc), switch to the Startup apps tab, and sort the list by Startup impact. Any application marked High that you don't need immediately is a good candidate for disabling. Common examples include Spotify, Discord, Teams (Personal), OneDrive (if you don't actively use it), and manufacturer utilities.
Right-click an application and select Disable. This doesn't uninstall it—it simply prevents it from launching automatically. You can still open it manually whenever you need it.
Keeping only three to five essential startup apps instead of fifteen or more can significantly reduce boot time, especially on mid-range hardware.
🧠 6. Adjust Virtual Memory (Page File)
When your system memory becomes full, Windows uses storage space as virtual memory, also known as the page file. If the page file is too small, Windows may become less responsive during demanding workloads. While this is less noticeable on modern NVMe SSDs, manually configuring the page file can still benefit older HDD-based systems or PCs with 8 GB of RAM or less.
Go to System → Advanced system settings → Performance → Advanced → Virtual memory → Change. Windows automatically manages the page file by default, and this is the recommended option for most users. If you choose to configure it manually, uncheck Automatically manage paging file size for all drives and set a custom size. A commonly recommended guideline is an Initial size of 1.5× your RAM and a Maximum size of 3× your RAM. For example, a PC with 8 GB of RAM could use an initial size of 12,288 MB and a maximum size of 24,576 MB.
If your computer has multiple drives, keeping the page file on your fastest SSD helps virtual memory perform as efficiently as possible.
🔔 7. Disable Notifications & Widgets
The Windows 11 Widgets panel—the weather and news feed available from the taskbar—runs as a background process. It periodically retrieves content from Microsoft's servers and uses system memory even if you rarely interact with it.
To disable Widgets, go to Settings → Personalization → Taskbar and turn Widgets off. This removes the taskbar icon and prevents the Widgets feature from running in the background. If you only want quick access to weather information, a browser bookmark or lightweight weather application is often a more resource-efficient alternative.
While you're there, open Settings → System → Notifications and disable notifications for applications that don't need your attention. Reducing unnecessary notifications helps minimize background activity and can make Windows feel slightly more responsive over time.
🛡️ 8. Configure Windows Security Scan Schedules
Microsoft Defender is one of the best built-in antivirus solutions available, and it should remain enabled. However, scheduled scans can occasionally run while you're actively using your computer, resulting in temporary spikes in CPU, memory, and disk usage that make the system feel less responsive.
If needed, you can review Defender's scheduled scan task by opening Task Scheduler and navigating to Task Scheduler Library → Microsoft → Windows → Windows Defender. Depending on your Windows version and Automatic Maintenance settings, scan scheduling may already be managed automatically. If manual scheduling is available, you can adjust the scan to run during off-hours when you're unlikely to be using your PC.
While reviewing Windows Security, open Windows Security → Virus & threat protection → Manage settings. Keep Cloud-delivered protection and Automatic sample submission enabled, as they improve protection while reducing the need for some local analysis. Only consider disabling Controlled folder access if it's preventing trusted applications from working correctly.
💡 Bonus: One More Thing Worth Doing
If you haven't already, run Storage Sense (Settings → System → Storage → Storage Sense) to remove temporary files, Windows Update leftovers, and cached data automatically. Many systems recover between 5 and 20 GB of storage, and SSDs generally perform best when they have plenty of free space available.
💬 My Experience with These Fixes
After years of testing, troubleshooting, and optimizing Windows systems, I've consistently noticed the same pattern with Windows 11: even powerful hardware gradually feels less responsive if you leave every default setting untouched. On my primary workstation—a Ryzen 5 desktop with 16 GB of RAM and a fast NVMe SSD—I began noticing subtle performance degradation after several months of daily use. The Start menu occasionally hesitated, File Explorer felt heavier than expected, and idle CPU usage regularly hovered around 6–7%.
After applying these optimizations one by one, the improvements became immediately noticeable. Disabling unnecessary background apps, switching to the High Performance power plan, and turning off Widgets had the biggest impact. Those three adjustments alone reduced idle CPU usage from roughly 6–7% to a much steadier 2–3%, and the occasional Start menu micro-stutters disappeared.
Visual effects are another optimization I frequently recommend, particularly for laptops with integrated graphics. The interface becomes slightly simpler visually, but navigation feels noticeably smoother, especially on entry-level and mid-range systems.
Virtual memory is the only setting where I recommend being selective. On systems with 16 GB or more of RAM and a fast NVMe SSD, Windows' default automatic management works extremely well. Manual configuration is generally most beneficial for older computers with limited memory or traditional hard drives.
What I like most about these optimizations is that they rely entirely on built-in Windows features. There are no risky Registry modifications, no questionable "PC optimizer" utilities, and no unsupported tweaks. Spending just 15 to 20 minutes reviewing these settings can noticeably improve your PC's responsiveness, especially if you use Windows every day.
Final Thoughts
Windows 11 is a capable operating system, but its default configuration is designed to balance compatibility, security, Microsoft's ecosystem, and power efficiency rather than maximize raw performance. Out of the box, it behaves more like a general-purpose platform than a finely tuned workstation. These eight adjustments help shift the system toward a more performance-focused configuration, allowing your hardware to deliver the responsiveness it's capable of.
You don't need to apply every tweak. Even two or three of them—especially managing Startup Programs, limiting Background Apps, and selecting the appropriate Power Plan—can reduce much of the unnecessary background overhead that affects everyday responsiveness. For many users, those changes alone are enough to make Windows 11 feel noticeably faster and more consistent.

❓ Windows 11 Performance – FAQ
Does Windows 11 get slower over time?
Yes, it often does—not because Windows "wears out," but because more apps, services, startup items, and background tasks accumulate over time. Startup programs, background apps, telemetry, widgets, and scheduled maintenance can all contribute to gradually reduced responsiveness.
What are the most effective settings to speed up Windows 11?
The biggest improvements usually come from disabling unnecessary startup programs, turning off background apps you don't use, switching to a High Performance power plan, and disabling Widgets. These changes reduce constant background activity and make the system feel noticeably more responsive.
Is it safe to disable telemetry and diagnostic data in Windows 11?
Reducing diagnostic data to the minimum required level is safe and recommended for most home users. Completely disabling the DiagTrack service is also generally safe, but it's better suited to users who understand the trade-offs between privacy, diagnostics, and troubleshooting.
Should I use third-party "optimizer" tools for Windows 11?
In most cases, no. Windows 11 already includes the tools needed to maintain good performance. Many third-party optimization utilities make aggressive Registry changes, install additional services, or create their own background processes, which can cause more problems than they solve.
Do visual effects and animations really affect performance?
Yes, especially on systems with integrated graphics or older hardware. Animations, transparency, and shadows use additional GPU and CPU resources. Disabling them won't dramatically change Windows' appearance, but it can make the interface feel smoother and reduce minor stutters.
When should I tweak virtual memory (page file) in Windows 11?
If you have 8 GB of RAM or less, or you're still using a mechanical hard drive, manually configuring the page file may improve responsiveness during heavy workloads. On systems with 16 GB or more of RAM and a fast SSD, Windows' default automatic management is generally the recommended option.
Will these tweaks affect gaming performance on Windows 11?
Yes, generally in a positive way. Reducing background activity, choosing the right power plan, and limiting unnecessary services frees up CPU and memory resources for games. These tweaks are unlikely to produce dramatic FPS gains, but they can reduce frame-time spikes, minimize stuttering, and improve overall system responsiveness.
