Windows 11 looks clean and modern on the surface, but underneath all those animations, transparency effects, and background services, there are dozens of settings most users never touch. Many of these hidden options exist purely for performance tuning - they are not deleted or removed, just buried a few menus deep where casual users rarely go.
If your laptop or desktop feels slower than it used to, before you consider a factory reset or hardware upgrade, it is worth spending fifteen minutes adjusting these seven settings. None of them require third party software, none of them are risky, and all of them are fully reversible if you ever want to switch back to default.
Here are seven Windows 11 hidden settings that can genuinely boost performance in 2026.

1. Disable Startup Apps You Do Not Actually Need
Every time Windows boots, it quietly loads a list of background apps configured to launch automatically. Some of these are useful, like your antivirus, but many are not - things like cloud backup tools, chat apps, printer utilities, or software you installed once and forgot about. Each one of these adds extra seconds to your boot time and keeps eating a small slice of RAM in the background even after startup.
To fix this, open Task Manager by pressing Ctrl + Shift + Esc together, then click on the Startup Apps tab. Windows even shows you a rough "Startup impact" rating - High, Medium or Low - next to each app. Right click on anything you do not need running immediately at boot and select Disable. This does not uninstall the app, it simply stops it from auto launching, so you can always open it manually whenever you actually need it.
Most users can safely disable at least five to ten startup entries without noticing any negative effect on their daily workflow, while boot time can improve noticeably, sometimes by several seconds or more depending on how many apps were previously loading.
2. Turn On Storage Sense to Auto Clean Junk Files
Over months of regular use, Windows quietly accumulates temporary files, old update leftovers, previous Windows installation folders, and recycle bin clutter. This is one of the most overlooked reasons a system starts to feel sluggish, especially on laptops with smaller SSDs where free space runs low.
Storage Sense is a built in Windows 11 feature that automatically removes this junk on a schedule, without you needing to manually run cleanup tools every few weeks. To enable it, go to Settings > System > Storage, and turn on Storage Sense. From there, click into it and configure how often you want it to run - daily, weekly or monthly - and whether it should also clean out your Downloads folder and Recycle Bin automatically.
Keeping at least fifteen to twenty percent of your drive free is important for performance, since Windows uses free space for virtual memory, temporary caching, and file system operations. A drive that is nearly full will almost always feel slower, even on relatively powerful hardware.
3. Adjust Visual Effects for Best Performance
Windows 11 is designed with visual polish in mind - rounded corners, shadows, transparency, smooth animations when opening or minimizing windows. These effects look nice, but they do consume a small amount of GPU and CPU resources continuously, and on older or lower end hardware this can genuinely affect responsiveness.
To adjust this, search for "Adjust the appearance and performance of Windows" in the Start menu search bar and open it. Inside, you will see a list of visual effects with checkboxes. You can either select "Adjust for best performance," which disables all of them at once, or manually pick and choose which ones to keep - for example, keeping smooth scrolling and font smoothing while disabling shadows and animations.
On systems with 8GB RAM or less, or integrated graphics rather than a dedicated GPU, disabling most of these effects usually results in a noticeably snappier experience when opening apps, switching windows, or navigating menus.
4. Disable Background Apps Running Silently
Many apps continue running in the background even after you close their window, refreshing content, syncing data, or sending notifications. While useful for some apps like email clients, this silent activity adds up across dozens of installed apps and can quietly drain both battery life and system resources.
To control this, go to Settings > Apps > Installed Apps. Click the three dot menu next to any app and look for background permission options, or check Settings, Privacy and Security, then Background Apps for a centralized list depending on your Windows 11 version. Turn off background activity for apps you rarely use or do not need constantly updating in the background.
This is particularly effective on laptops, since reducing background activity directly improves both battery life and overall system responsiveness, especially when running multiple apps simultaneously.
5. Switch Power Mode to Best Performance
Windows 11 includes a power mode slider that many users never touch, often left on Balanced by default even on desktop PCs that are always plugged in and do not need to conserve battery at all.
Go to Settings > System > Power and Battery > Power Mode, and switch it to Best Performance. On laptops running on battery, you may want to keep Balanced mode active for battery life, but when plugged into power, switching to Best Performance mode allows the CPU to run at higher clock speeds more consistently rather than throttling down to save energy.
This setting alone can make a meaningful difference for tasks like video editing, gaming, or running multiple heavy applications at once, since the system stops artificially limiting performance to save power it does not currently need to conserve.
6. Disable Search Indexing for Drives You Rarely Search
Windows Search indexing runs constantly in the background, scanning your files so that search results appear instantly when you look for something. This is useful for your main system drive, but if you have secondary drives full of large media files, backups, or archives you rarely search through, indexing them continuously wastes CPU and disk resources for little practical benefit.
To adjust this, search for "Indexing Options" in the Start menu and open it. Click Modify, and uncheck any drives or folders you do not need indexed, such as backup drives or large media libraries. This reduces background disk activity, which is especially noticeable on systems using traditional hard drives rather than SSDs, where indexing can cause visible slowdowns during heavy read or write operations.
7. Turn Off Transparency Effects System Wide
Beyond the visual effects mentioned earlier, Windows 11 also applies transparency to the taskbar, Start menu, and various system panels by default. While visually appealing, this transparency effect requires constant GPU rendering calculations to blend the background through these elements in real time.
To disable it, go to Settings > Personalization > Colors, and turn off the Transparency Effects toggle. This is a small change individually, but combined with the other visual effect adjustments mentioned earlier, it further reduces GPU load, particularly helpful on systems with integrated graphics rather than dedicated graphics cards.
Summary Table
| # | Setting | Where to Find It | Main Benefit |
|---|---|---|---|

| 3 | Adjust Visual Effects | Search "Adjust appearance and performance" | Reduces CPU/GPU load from animations |
| 4 | Disable Background Apps | Settings > Apps > Installed Apps | Saves battery and system resources |
| 5 | Switch to Best Performance Power Mode | Settings > System > Power and Battery | Higher sustained CPU performance |
| 6 | Disable Search Indexing on Unused Drives | Indexing Options | Reduces background disk activity |
| 7 | Turn Off Transparency Effects | Settings > Personalization > Colors | Lowers GPU rendering load |
Final Thoughts
None of these seven settings require any technical expertise, third party software, or system reinstalls - they are all built directly into Windows 11 and fully reversible if you ever change your mind. On modern high end hardware, the difference from these tweaks might be subtle, but on mid range or older laptops, particularly those with integrated graphics or limited RAM, the combined effect of these changes can genuinely make daily use feel noticeably faster and smoother.
Start with the startup apps and visual effects settings first, since those typically show the most immediate improvement, then work through the remaining tips over time. A faster Windows 11 experience in 2026 does not always require new hardware - sometimes it just requires finding the settings that were hidden in plain sight all along.
