If your computer is dragging its feet, you’re likely wondering how to speed up Windows 11 without sacrificing system stability or losing your favorite features. Trust me, you aren’t the only one dealing with this frustrating slowdown.

Underneath that sleek, modern design, Windows 11 is packed with demanding visual effects, background telemetry, and its fair share of pre-installed bloatware. These under-the-hood elements quietly eat up your CPU cycles and RAM. Before long, you’re left dealing with annoying input lag, painfully slow boot times, and a noticeable dip in your daily productivity.

In this guide, we’ll walk through exactly how to speed up Windows 11. We’ll cover everything from quick, everyday fixes to advanced, IT-level optimizations designed to squeeze every ounce of performance out of your machine. Whether you’re a casual browser or a hardcore power user, these actionable steps will help get your PC running like new again.

Why Windows 11 Gets Slow: The Technical Causes

Before we dive right into the solutions, it helps to understand exactly why Windows 11 bogs down in the first place. More often than not, the main culprits are a combination of heavy background processes, added security overhead, and a highly resource-intensive interface.

For starters, the OS utilizes a brand-new UI framework that relies heavily on transparency effects and fluid animations—most notably the new “Mica” material design. While these aesthetic touches look absolutely incredible on high-end displays, they demand constant GPU and CPU rendering. As you can imagine, this puts quite a strain on budget laptops or older desktop builds.

Additionally, the operating system enables Virtualization-Based Security (VBS) and Memory Integrity by default on most fresh installs. While this is fantastic for enterprise-grade security, VBS introduces a layer of hardware virtualization that can actually reduce gaming and compute performance by as much as 15%. When you mix that virtualization overhead with aggressive background telemetry, annoying startup bloatware, and unoptimized power settings, your system creates a bottleneck in no time.

Quick Fixes to Speed Up Windows 11

If you’re looking for ways to make Windows 11 faster right this second, you’ll want to start with these simple but highly effective tweaks. Taking just a few minutes to apply these adjustments can drastically improve your PC’s speed, making them the perfect starting point.

Disable Startup Apps: Programs launching alongside your boot sequence are the number one cause of painfully slow startup times. To fix this, press Ctrl + Shift + Esc to pull up the Task Manager. Head over to the Startup tab, right-click any non-essential apps (like Skype or Spotify), and hit Disable.
Turn Off Visual Effects: Hit the Windows key, search for “View advanced system settings,” and press Enter. From there, look under the Performance section, click Settings, select “Adjust for best performance,” and hit Apply. This will turn off those resource-heavy animations.
Uninstall Bloatware: Out of the box, Windows 11 comes packed with several unwanted third-party apps. Head to Settings > Apps > Installed apps to clean house. Go ahead and remove pre-installed games, trial anti-virus programs, and manufacturer bloatware that you know you’ll never touch.
Disable Background Apps: You don’t want unused apps running silently in the background. Navigate to Settings > System > Power & battery, where you can optimize your battery usage parameters to restrict unnecessary background application activity.
Turn Off Notifications: Endless pop-ups don’t just interrupt your workflow; they also drain system resources. Go to Settings > System > Notifications and simply turn off alerts for any applications you don’t actively need to monitor.
Pause OneDrive Syncing: Unless you rely on real-time cloud backups, try right-clicking the OneDrive icon in your system tray to pause syncing. Constant file syncing eats up a surprising amount of network bandwidth and disk I/O.

For most people, running through this quick checklist is more than enough to iron out basic performance hiccups and optimize Windows 11 for a fluid, everyday experience.

Advanced Solutions for IT and Power Users

If you’re a software developer, heavy gamer, or IT professional, basic visual tweaks probably won’t cut it. To really move the needle, we need to dig a little deeper into the system architecture to reclaim those wasted CPU cycles and free up RAM. Let’s look at some advanced ways to supercharge your performance.

Disable Virtualization-Based Security (VBS)

If you use your computer heavily for gaming, 3D rendering, or demanding code compilation, disabling VBS can provide a highly noticeable speed boost. Just keep in mind that this does slightly reduce your protection against sophisticated memory attacks. You should only proceed with this step if you practice safe browsing habits and run solid antivirus software.

To turn it off, open the Windows Start menu and search for “Core Isolation.” Simply toggle the “Memory Integrity” switch to the off position, then restart your PC. This effectively removes the hypervisor overhead tied to VBS, giving you back your raw hardware power.

Disable the SysMain (Superfetch) Service

SysMain—which used to go by the name Superfetch—attempts to preload your most frequently used apps directly into your RAM. While this was genuinely helpful back in the era of spinning mechanical hard drives, it frequently causes the dreaded 100% disk usage bug on modern setups. If you’re running a fast NVMe SSD, you honestly don’t need this service running.

To shut it off, press Win + R, type services.msc, and hit Enter. Scroll down the list until you spot “SysMain”, right-click it, and choose Properties. From there, change the Startup type to Disabled, click Stop, and apply your new settings.

Switch to the Ultimate Performance Power Plan

Out of the box, Windows 11 defaults to a “Balanced” power plan designed to save energy and stretch out battery life on laptops. However, if you want to unlock maximum CPU frequencies on a desktop rig, open up the Command Prompt as an administrator and run the following command:

powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Once you’ve successfully run that command, head into the classic Control Panel, navigate to Power Options, and choose your newly unlocked “Ultimate Performance” plan. Doing this ensures your processor won’t downclock itself just to save a bit of power.

Debloat Telemetry via Group Policy

Microsoft relies on background telemetry services to constantly send diagnostic data back to their servers. If you happen to be running Windows 11 Pro or Enterprise, you can completely disable this data collection. Just press Win + R, type gpedit.msc, and navigate your way through Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds. Find “Allow Diagnostic Data,” double-click it, and switch it to Disabled.

Best Practices for Windows 11 Optimization

Optimizing your operating system isn’t something you do once and forget about—it requires a bit of proactive, ongoing maintenance. Keeping your system in peak condition guarantees long-term stability, speed, and security.

Enable Storage Sense: Make your way to Settings > System > Storage and toggle Storage Sense on. This brilliant feature automatically cleans out temporary files, clears cache data, and empties your recycle bin on a routine schedule without you having to lift a finger.
Keep Drivers Updated: Running outdated GPU or motherboard chipset drivers is a guaranteed way to cause severe performance bottlenecks. Make it a habit to regularly check Windows Update or utilize your hardware manufacturer’s official update software.
Maintain SSD Health: You should never run traditional defragmentation on a modern Solid State Drive. Instead, make sure the TRIM command is active by optimizing the drive through the built-in “Defragment and Optimize Drives” tool.
Run Routine Malware Scans: Hidden adware, malware, and rogue crypto-miners can seriously tank your computer’s performance. Play it safe by scheduling weekly quick scans via Windows Defender or your preferred third-party security suite.

Recommended Tools and Resources

Sometimes, tinkering with built-in Windows settings just isn’t enough to get the results you want. By leaning on powerful third-party software and making a few strategic hardware upgrades, you can truly take your machine’s performance to the next level.

Hardware Upgrade (SSD): Making the jump from an older SATA drive to an NVMe SSD is arguably the biggest performance leap you’ll ever experience. We highly recommend looking into drives like the Samsung 980 PRO NVMe SSD if you’re after blazing-fast read and write speeds.
RAM Upgrade: Do you constantly multitask, edit heavy video files, or spin up Docker containers? If so, upgrading to 32GB of RAM is an incredibly worthwhile investment. Reliable memory kits like the Corsair Vengeance DDR5 offer exceptional speeds and stability.
Uninstaller Utilities: Programs like Revo Uninstaller or Geek Uninstaller are lifesavers. They help completely wipe out stubborn bloatware and leftover registry keys that the standard Windows uninstaller almost always misses.
System Cleaners: We recommend trying out BleachBit. It’s a fantastic, open-source alternative to CCleaner that lets you thoroughly scrub temporary files away—without forcing you to deal with intrusive ads or background tracking.

Frequently Asked Questions (FAQ)

Does adding more RAM speed up Windows 11?

Yes, without a doubt. Windows 11 consumes a pretty hefty chunk of RAM (usually around 4GB) just sitting idle on your desktop. If your machine is only running on 8GB, firing up a few heavy browser tabs alongside a productivity app will max out your memory surprisingly fast. When that happens, Windows is forced to use your hard drive as virtual memory, which instantly causes system lag. Bumping your system up to 16GB or 32GB will provide a massive, noticeable boost to your overall responsiveness.

Will disabling visual effects make a big difference?

Turning off visual effects can make a night-and-day difference, especially on older CPUs or computers relying on integrated graphics. By shutting off transparency animations, drop shadows, and smooth scrolling, your processor can finally dedicate its power to running your actual software instead of struggling to render the desktop UI.

Why is Windows 11 slower than Windows 10?

It’s a common complaint. Many users feel Windows 11 is slower than its predecessor, mostly because of its much stricter security defaults—like VBS and Core Isolation—combined with those heavy visual design updates. While these modern features definitely make the OS more secure and visually stunning, they fundamentally demand more capable, modern hardware to run as smoothly as the older Windows 10 architecture did.
