WINDOWS 11 CETTE ASTUCE TOUTE SIMPLE RENDRA VOTRE PC BEAUCOUP PLUS RAPIDE EN SEULEMENT QUELQUES

Windows 11 : Cette Astuce Toute Simple Rendra Votre PC Bien Plus Rapide En Quelques Clics

Windows 11 represents a significant visual leap forward from its predecessors, introducing a translucent design language known as Mica, rounded corners, and fluid animations designed to make the user experience feel more modern and responsive. However, this aesthetic refinement comes at a tangible cost to system resources. Every time you minimize a window, open the Start Menu, or switch between applications, the Graphics Processing Unit (GPU) and the Central Processing Unit (CPU) must render complex animations and transparency effects. For users running high-end gaming rigs, these overheads are negligible. But for the vast majority of users relying on laptops, older desktops, or systems with integrated graphics, these visual flourishes can introduce noticeable input lag, stuttering, and a general lack of snappiness.

We understand that performance is paramount. Whether you are a professional seeking a lag-free workflow, a gamer demanding maximum frame rates, or simply a user who prefers a responsive system, optimizing Windows 11 is essential. The “simple trick” that yields significant speed improvements is the aggressive optimization of visual effects and the reduction of background UI rendering. This article provides a comprehensive, step-by-step guide to unlocking the hidden performance potential of your operating system by minimizing the visual load. We will go beyond basic advice and delve into advanced configurations, system-level tweaks, and background process management to ensure your PC runs at peak efficiency.

Understanding the Visual Cost of Windows 11

Before applying fixes, it is crucial to understand what is happening under the hood. Windows 11 relies heavily on the Windows Display Driver Model (WDDM) and DirectX 12 Ultimate to render its interface. The operating system prioritizes visual smoothness over raw efficiency by default. This is achieved through several mechanisms:

For a high-end workstation with a dedicated NVIDIA RTX 4090, this overhead is irrelevant. However, for a standard business laptop with Intel UHD Graphics or an older AMD APU, these rendering tasks compete directly with your web browser, spreadsheet software, and video conferencing tools for limited GPU bandwidth. By reducing or eliminating these effects, we offload the GPU, reduce DWM memory usage, and minimize CPU interruptions, resulting in a system that feels instantly responsive.

Method 1: The Performance Options Interface (The Core Fix)

The most effective and immediate way to speed up Windows 11 is through the Performance Options dialog. This menu allows you to decouple visual aesthetics from system functionality. It is a native feature that does not require third-party software or registry hacks, making it safe and reversible.

We will begin by accessing the system properties. This is the foundational step for our optimization process.

  1. Press the Windows Key on your keyboard and type View advanced system settings.
  2. Click on the “View advanced system settings” Control Panel result that appears under “Best match.”
  3. A “System Properties” window will open. Ensure you are on the Advanced tab.
  4. In the “Performance” section, locate and click the Settings button.

This opens the Performance Options window. By default, Windows 11 is set to “Adjust for best appearance.” This setting enables every single visual effect, including animations, shadows, and transparent glass effects. To maximize speed, we must change this.

Configuring “Adjust for Best Performance”

Once the Performance Options window is open, you will see a list of checkboxes representing specific visual features.

  1. Select the radio button labeled Adjust for best performance.
  2. Upon selecting this, Windows will immediately uncheck all boxes. This strips the interface of all non-essential visuals. The title bars will become a solid color, the taskbar will lose its transparency, and all window animations (minimize/maximize) will be disabled.

The Critical Exception for Usability While “Adjust for best performance” offers the fastest experience, it can make the interface feel stark and difficult to use, particularly because it disables font smoothing. To retain a balance of speed and readability, we recommend enabling just one specific option:

By keeping only font smoothing enabled, you eliminate roughly 80% of the visual overhead. The Start Menu will open instantly, window switching becomes instantaneous, and the system feels significantly snappier because the GPU no longer has to render complex transparency layers and animation frames.

Advanced System Performance Settings

Within the same “Performance Options” window, navigate to the Advanced tab. Here, we address how the system handles background tasks and processor scheduling.

Processor Scheduling

Look for the section labeled “Processor scheduling.” You have two options:

Ensure Programs is selected. This tells Windows to allocate CPU resources to the app you are currently using rather than background maintenance tasks, further enhancing the feeling of speed.

Virtual Memory (Paging File)

Virtual memory acts as an overflow for your RAM. When your physical memory (RAM) is full, Windows moves data to your storage drive (SSD or HDD). While necessary, relying too heavily on it can slow down the system.

  1. In the “Advanced” tab, under “Virtual memory,” click Change.
  2. Uncheck Automatically manage paging file size for all drives.
  3. If you have 16GB of RAM or more, you can often set the paging file to a fixed size (e.g., 1024 MB initial and maximum) or even disable it entirely on some systems, though we recommend keeping a small one for crash dump generation.
  4. For systems with 8GB or less, ensure the paging file is set to a fixed size rather than system managed to prevent fragmentation. A good rule of thumb is to set the size to 1.5x your physical RAM.

This reduces the stuttering that occurs when Windows frantically writes data to the disk during multitasking.

Method 2: Disabling Startup Bloat and Background Apps

Visual effects are not the only cause of sluggishness. Background processes consume CPU cycles and RAM, leaving less capacity for your active work. A “fast” PC is often just a PC with fewer unnecessary processes running.

The Startup Audit

Every application that claims a spot in your taskbar tray or launches silently at boot delays your system’s readiness.

  1. Open Task Manager (Ctrl + Shift + Esc).
  2. Go to the Startup apps tab (or “Startup” in the left sidebar).
  3. Sort by “Startup impact” to see which apps are heaviest.
  4. Right-click and Disable any non-essential software. Common culprits include updaters for hardware you rarely use, cloud storage sync clients you don’t need immediately at boot, and chat applications (Discord, Skype, Teams).

Disabling these can shave seconds off your boot time and free up hundreds of megabytes of RAM immediately.

Background Apps Permissions

Windows 11 allows apps to run in the background to update live tiles or send notifications. This drains battery and CPU.

  1. Open Settings > Apps > Installed apps.
  2. Click the three dots next to an app and select Advanced options.
  3. Under “Background apps permissions,” select Never.

We recommend doing this for utility apps, file managers, and installers that do not require real-time notifications. Keep permissions active for communication apps like email or messaging.

Method 3: Optimizing Storage and Indexing

A slow hard drive is a major bottleneck. Even with a solid-state drive (SSD), misconfigured indexing can cause random spikes in disk usage, freezing the system.

Windows Search Indexing

The indexer scans your files to make search results appear faster. However, on older drives, the indexing process itself can cause stuttering.

  1. Open Settings > Privacy & security > Search permissions.
  2. Scroll down to Windows Indexing and click Enhanced.
  3. Review the list of included locations. If you have folders containing thousands of temporary files or large archives, remove them from the index.
  4. For users with very slow HDDs, consider turning off indexing entirely for specific drives by right-clicking the drive in File Explorer > Properties > uncheck “Allow files on this drive to have contents indexed.”

Storage Sense

Storage Sense automatically frees up space by deleting temporary files and emptying the Recycle Bin. A cluttered drive slows down file access times.

  1. Go to Settings > System > Storage.
  2. Toggle Storage Sense to On.
  3. Click “Storage Sense” to configure it. Set it to run “Every day” or “Every week” if you are a heavy user, and configure it to delete files in the Downloads folder that have been there for over 30 days.

Method 4: Power Plan and Hardware Acceleration

To truly extract maximum speed, we must look at how Windows manages power and hardware resources.

Ultimate Performance Power Plan

By default, Windows uses “Balanced” power plans, which throttle CPU frequency to save energy. This introduces micro-latencies. You can unlock the hidden “Ultimate Performance” plan:

  1. Open Command Prompt as Administrator.
  2. Enter the following command: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
  3. Go to Settings > System > Power & battery > Power mode.
  4. You will now see “Ultimate Performance” in the dropdown.

This plan prevents hard drives from sleeping and keeps the CPU running at higher frequencies, eliminating the slight delay (latency) involved in ramping up performance from an idle state.

Hardware Accelerated GPU Scheduling (HAGS)

HAGS allows your GPU to manage its own video memory, reducing CPU overhead.

  1. Go to Settings > System > Display > Graphics settings.
  2. Toggle Hardware-accelerated GPU scheduling to On.
  3. Restart your computer.

This is particularly effective for gaming and video editing, but it also benefits general UI fluidity on modern GPUs (Nvidia GTX 10-series and newer, AMD RX 5000 series and newer).

Method 5: Visual Effects Registry Tweaks (Advanced)

For power users, we can push the visual effect reduction even further via the Windows Registry. This allows us to disable specific animations that the standard UI does not expose.

Warning: Always back up your registry before making changes.

Disabling Window Animations

Window animations (the sliding effect when minimizing or restoring) consume a surprising amount of GPU resources.

  1. Press Win + R, type regedit, and hit Enter.
  2. Navigate to: HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
  3. Look for a value named MinAnimate. If it does not exist, create a new String Value named MinAnimate.
  4. Set the value to 0.
  5. If you want to disable the fading effect of menus, navigate to HKEY_CURRENT_USER\Control Panel\Desktop and find UserPreferencesMask. Change the second byte to 90 (e.g., if the default is 9E 3E 07 80, change it to 90 3E 07 80). This disables menu fading.

Disabling Mouse Hover Popups

The delay before a tooltip appears can be annoying and adds to the perception of sluggishness.

  1. Navigate to HKEY_CURRENT_USER\Control Panel\Mouse.
  2. Find MouseHoverTime. Change the value to 1 (milliseconds) or 0 (instant). This makes tooltips appear instantly when you hover over icons.

Method 6: Driver and Firmware Updates

Software optimization can only go so far if the hardware drivers are outdated. The communication layer between the OS and the hardware is critical for speed.

GPU Drivers

Do not rely solely on Windows Update for graphics drivers. NVIDIA, AMD, and Intel frequently release “Game Ready” or “Performance” drivers that specifically address UI responsiveness.

Chipset Drivers

The motherboard chipset controls how the CPU communicates with RAM and storage. Go to your motherboard manufacturer’s website (Dell, HP, MSI, ASUS, etc.) and download the latest chipset drivers. This often resolves issues with USB latency and disk I/O speeds.

Method 7: Disk Optimization and TRIM

For SSDs (Solid State Drives), the TRIM command is vital. It allows the OS to tell the SSD which data blocks are no longer in use and can be wiped internally. Without TRIM, SSD write speeds degrade over time.

  1. Type Defragment and Optimize Drives in the Windows search bar.
  2. Select your SSD drive.
  3. Click Optimize.
  4. Ensure “Scheduled optimization” is turned on. Windows automatically runs TRIM weekly, but manually triggering it ensures the drive is fresh.

For HDDs (Hard Disk Drives), defragmentation is still relevant. Windows handles this automatically, but checking the status ensures the file system is organized for faster read speeds.

Method 8: Network and System Responsiveness

A slow network can make a PC feel sluggish, especially when apps hang waiting for a connection timeout.

Disable Network Throttling

Windows has a feature called “Network Throttling” that limits network bandwidth when media playback is detected. This can interfere with high-speed data transfers.

  1. Open regedit.
  2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile.
  3. Create a new DWORD (32-bit) Value named NetworkThrottlingIndex.
  4. Set the value to FFFFFFFF (hexadecimal) to disable throttling.

Disable Large Send Offload (LSO)

LSO allows the network card to send large packets of data, but it can cause latency spikes on some hardware.

  1. Open Device Manager.
  2. Expand Network adapters.
  3. Right-click your adapter > Properties > Advanced tab.
  4. Look for Large Send Offload v2 (IPv4) and set it to Disabled. Do the same for IPv6 if available.

Method 9: Cleaning Temporary Files and Caches

Over time, Windows accumulates gigabytes of temporary files, icon caches, and browser caches that slow down file explorer and web browsing.

Clearing the Icon Cache

Corrupted or bloated icon caches can cause File Explorer to lag or display blank icons.

  1. Open Command Prompt as Administrator.
  2. Navigate to the local app data folder by typing: cd %userprofile%\AppData\Local
  3. Navigate to the Microsoft folder: cd Microsoft\Windows\Explorer
  4. Delete the icon cache files: del iconcache*
  5. Restart the PC.

Disk Cleanup Utility

  1. Search for Disk Cleanup.
  2. Select your system drive (usually C:).
  3. Click Clean up system files. This will scan for old Windows installations (Windows.old) which can take up 20GB+ of space.
  4. Check all boxes, including Temporary Internet Files, Delivery Optimization Files, and Thumbnails.
  5. Click OK to delete.

Method 10: Game Mode and Input Responsiveness

Even if you aren’t a gamer, the “Game Mode” in Windows 11 can improve general performance by prioritizing your foreground application.

  1. Go to Settings > Gaming > Game Mode.
  2. Toggle Game Mode to On.

When Game Mode is active, Windows suppresses background activities like Windows Update and driver installations, and it prevents the OS from stealing GPU cycles for background windows. This ensures that your active application receives the maximum available resources, reducing input lag.

Reducing Mouse Latency

Input lag makes a system feel slower than it actually is.

  1. Search for Mouse settings.
  2. Click Additional mouse options.
  3. Go to the Pointer Options tab.
  4. Uncheck Enhance pointer precision. This disables mouse acceleration, which can cause inconsistent cursor movement and perceived input lag. While this is a preference, many power users prefer raw input for a “snappier” feel.

Method 11: Windows 11 Bloatware Removal

Windows 11 comes pre-installed with applications like News, Weather, Finance, and Maps. These run in the background, collecting data and consuming resources.

While you cannot uninstall all of them via the standard Settings menu, we can use PowerShell to remove them.

  1. Open PowerShell as Administrator.
  2. To remove the News and Interests feed (Widgets), you can run: `Get-AppxPackage *Microsoft.Bing
