If your PC feels sluggish, you don’t always need new hardware to get a snappier experience. A handful of tucked-away Windows settings can shave seconds off everyday tasks like booting, opening apps, and switching between windows. Better yet, most of these changes are reversible and don’t require third-party “optimizer” tools. In this guide, you’ll unlock seven lesser-known tweaks that improve Windows speed by reducing background load, cutting unnecessary visuals, and keeping your system focused on what you’re doing right now. Follow along step by step, and you’ll likely notice faster startups, smoother multitasking, and fewer annoying slowdowns—especially on laptops and older PCs.
1) Turn off startup apps you don’t need (without breaking anything)
Startup programs are one of the most common reasons a PC feels slow right after boot. Many apps quietly add themselves to startup so they can “help,” check for updates, or run a tray icon. Each one uses CPU time, memory, and disk activity right when you’re trying to start working.
How to disable startup apps in Task Manager
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Startup apps (Windows 11) or the Startup tab (Windows 10).
3. Sort by Startup impact.
4. Right-click any non-essential app and choose Disable.
A practical rule: if you don’t recognize it, don’t disable it until you confirm what it is. Focus on obvious candidates like launchers, chat tools you don’t use daily, and manufacturer “assistants.”
Examples of apps that are often safe to disable at startup:
– Spotify (if you don’t need it immediately)
– Zoom/Teams (unless you’re always on calls)
– Game launchers (Steam, Epic, etc.)
– Printer “status monitor” utilities (printing still works without them)
What to keep enabled (to avoid headaches)
Keep anything that looks like security software, touchpad drivers, audio drivers, or “Windows Security notification icon.” Those may be involved in protection or core device features. Disabling the wrong driver helper can cause missing gestures, broken hotkeys, or audio glitches—rare, but avoidable.
This one change alone can noticeably improve Windows speed during boot and the first few minutes after login.
2) Enable “Efficiency mode” for background hogs
Windows 11 includes a relatively hidden performance lever: Efficiency mode. It reduces the priority and power usage of a process that’s chewing through CPU in the background, helping your system stay responsive.
When Efficiency mode helps most
Use it when:
– A browser tab or app starts consuming lots of CPU
– You’re on a laptop and want cooler, quieter operation
– You’re multitasking (video call + browser + spreadsheets) and things feel laggy
How to turn it on
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Processes.
3. Right-click the app/process that’s using high CPU.
4. Select Efficiency mode (if available) and confirm.
Tip: Start with web browsers if they’re spiking CPU (Chrome/Edge) and with any app you’re not actively using but can’t close yet.
Note: Some processes won’t allow Efficiency mode, and that’s normal. Don’t force-stop critical Windows processes. The goal is smoother Windows speed, not a risky “clean-up.”
3) Reduce visual effects that secretly slow older PCs (Windows speed boost)
Animations and transparency can make Windows look polished, but they also consume GPU/CPU resources—especially on integrated graphics or older machines. Reducing a few effects can make opening menus, switching windows, and navigating feel instantly snappier.
Disable transparency and animation (quick wins)
1. Go to Settings.
2. Select Accessibility (Windows 11) or Ease of Access (Windows 10).
3. Find Visual effects.
4. Turn off:
– Animation effects
– Transparency effects
You can also try:
– Settings > Personalization > Colors > Transparency effects (toggle off)
Use the classic “Performance Options” panel for deeper control
1. Press Windows key and type: Advanced system settings
2. Open it and under Performance click Settings.
3. Choose Adjust for best performance, or manually uncheck:
– Animate windows when minimizing and maximizing
– Fade or slide menus into view
– Show shadows under windows
If you still like a bit of polish, keep “Smooth edges of screen fonts” on. It doesn’t cost much and makes text easier to read.
This is one of the few tweaks that can make Windows speed feel better immediately because it reduces the delay you perceive in everyday UI actions.
4) Stop Windows from indexing everything (smart indexing instead)
Windows Search indexing can be helpful, but on some PCs it creates constant disk activity—especially if you have lots of files or an older HDD. The trick is not necessarily to disable indexing entirely, but to limit it so Windows only indexes what you actually search.
Restrict indexing to key folders
1. Open Settings.
2. Go to Privacy & security > Searching Windows (Windows 11) or Search > Searching Windows (Windows 10).
3. Choose Classic (indexes Desktop, Documents, Pictures, and Music only) instead of Enhanced.
Then review excluded folders. Excluding large folders you rarely search (archives, game folders, VM images) can reduce background load.
Rebuild the index if search is slow or buggy
If search results are delayed or incorrect, rebuilding can help:
1. Settings > Privacy & security > Searching Windows
2. Find Advanced indexing options.
3. Select Advanced > Rebuild.
Why this matters: constant indexing on a busy drive competes with app loading and can drag down Windows speed, especially during heavy multitasking.

5) Change power settings from “balanced” to real performance
Many PCs default to Balanced power mode. That’s fine for battery life, but it can downshift performance in moments when you want responsiveness. Adjusting power mode won’t turn a low-end laptop into a workstation, but it can reduce “hesitation” and improve perceived speed.
Pick the right power mode for how you use your PC
1. Open Settings.
2. Go to System > Power & battery (Windows 11) or System > Power & sleep (Windows 10).
3. Under Power mode, choose:
– Best performance (plugged in, heavy multitasking)
– Balanced (general use)
– Best power efficiency (battery-first)
If your PC feels slow even while plugged in, try Best performance and test for a day.
Enable “Ultimate Performance” (where available)
Some systems (often Pro editions or certain hardware) support the Ultimate Performance plan.
1. Press Windows key, type: Control Panel, and open it.
2. Go to Hardware and Sound > Power Options.
3. Look for Ultimate Performance.
If you don’t see it, don’t worry—Best performance in Settings is usually enough. Just remember: higher performance modes can increase fan noise and reduce battery runtime.
This setting is a clean, Windows-native way to improve Windows speed without installing anything.
6) Trim background permissions: stop apps from running when you’re not using them
Background activity is sneaky. Some apps continue syncing, polling, updating, or sending notifications long after you stop using them. That’s not always bad, but too many background tasks can chip away at memory and CPU—leading to slowdowns over time.
Disable background permissions for non-essential apps (Windows 11)
1. Go to Settings > Apps > Installed apps.
2. Click the three dots next to an app > Advanced options.
3. Under Background apps permissions, set it to Never (for apps that don’t need background activity).
Good candidates:
– Retail/store apps you rarely open
– Secondary chat apps
– Trialware from the manufacturer
– Social media apps
Use “Background apps” controls (Windows 10)
1. Settings > Privacy > Background apps
2. Turn off apps you don’t need running in the background.
If you rely on timely notifications (mail, messaging), keep those enabled. The goal is to cut silent resource drain and keep Windows speed consistent throughout the day.
7) Turn off optional Windows features that add overhead
Windows ships with features many people never use—virtualization tools, legacy components, media features, and more. Some can add background services or increase complexity. Disabling what you don’t need can reduce startup tasks and keep your system lean.
Review and remove optional features safely
1. Open Settings.
2. Go to Apps > Optional features.
3. Remove features you don’t use.
Common optional items people remove:
– Internet Explorer mode components (varies by version)
– Windows Media Player/legacy media features (if unused)
– Steps Recorder (if present and unused)
Disable Windows features from the classic panel (advanced)
1. Press Windows key and type: Windows Features
2. Open Turn Windows features on or off.
3. Carefully uncheck features you don’t use, such as:
– Hyper-V (if you don’t run virtual machines)
– Windows Sandbox (if you don’t use it)
– Work Folders Client (rare for home users)
Important caution: If you use WSL (Windows Subsystem for Linux), virtualization-based security, Docker, or virtual machines, don’t disable Hyper-V-related features. If you’re unsure, change one thing at a time and restart to test stability.
Reducing unnecessary features won’t always create a dramatic benchmark jump, but it can improve Windows speed by cutting background services and keeping the system simpler.
Key takeaways and your next step
If your PC has been feeling slow, these seven settings target the most common hidden causes: too many startup apps, unnecessary background activity, heavy visuals, overly aggressive indexing, and conservative power limits. Start with startup apps and visual effects for the fastest “feel” improvement, then move on to indexing, power mode, and background permissions to keep performance steady all day. Small changes stack up, and the result is usually smoother multitasking and faster everyday responsiveness—real Windows speed you can feel.
