Friends, if your Windows 11 is running slowly, you are not alone. I personally faced this very issue on my laptop last year – as soon as I started my office work in the morning, it would take 20–30 seconds just for the browser to open; file transfers would freeze, and during gaming, the FPS would drop so low that playing became nearly impossible. Slow performance issues with Windows 11 are quite common these days, especially on older hardware or systems that haven’t undergone proper maintenance. People search for solutions to this because they want their PC to run faster without having to buy a brand-new laptop.
Today, I’m going to give you a step-by-step guide that actually works. These are fast methods – some take just 5 minutes, others 15. I’ve tried them myself, applied them to my friends’ PCs, and seen the results firsthand. No registry cleaners or fake tools – just proven methods. Let’s get started and fix the Windows 11 slowdown issue once and for all.
Why Does Windows 11 Slow Down? Understand the Real Reasons.
First, you should know that there are 5–6 main reasons behind Windows 11 running slowly. Most people assume it is simply because they have an old PC, but in reality, the issue stems from software-related problems.
- 15–20 programs run in the background at startup (such as iTunesHelper, OneDrive, and Skype).
- The SSD also slows down when the disk becomes full.
- Outdated drivers or missing Windows updates.
- Visual effects (animations, transparency) that consume RAM.
- Malware or junk files.
- Power settings are set to Balanced mode, which reduces performance.
My own example: My laptop with 8GB of RAM running Windows 11 had slowed down because 12 apps were running at startup. When I opened the Task Manager to check, the CPU usage was at 70%. After fixing this, the speed doubled. If your Windows 11 system is also running slowly, start by opening the Task Manager (Ctrl + Shift + Esc) – it will provide you with your biggest clue.
Step 1: Check for Windows Updates and Drivers – The Easiest and Fastest Method
The first and most crucial step in fixing a slow Windows 11 system is updating. Microsoft itself states that updates improve performance.
Go to Settings > Windows Update and click “Check for updates.” If the 25H2 update is available (which is expected to fix performance issues in 2026), install it.
For drivers: Open Device Manager (Win + X > Device Manager), right-click on “Display adapters” and “Network adapters,” and select “Update driver.” I updated my NVIDIA GPU driver, and my gaming performance saw an increase of 20–30 FPS.
Tip: Schedule updates so that restarts do not occur during working hours. Enable the “Get me up to date” option under Advanced options. This resolves Windows 11 performance issues by up to 30%. Know More: If you encounter difficulties with updates, check out fixtech.in for professional assistance.
Step 2: Disable Startup Programs – Instantly Speed Up a Slow Windows 11 System
This is the fastest method. On most PCs, 10–15 apps load at startup and consume RAM.
Open Task Manager > Go to the Startup tab. Disable high-impact apps (such as Adobe, Spotify, and Discord). My case: After disabling OneDrive and Cortana, the boot time dropped from 40 seconds to 15 seconds.
Simple Steps in Bullet Points:
- Press Ctrl + Shift + Esc.
- Click on the Startup tab.
- Right-click on each entry > Disable.
- Keep only the essentials – Antivirus, GPU software.
- Advanced controls via MSCONFIG (Win + R > msconfig > Startup).
Edge case: If you are a gamer, keep Game Mode enabled, but disable non-gaming apps. Startup is more resource-intensive in Windows 11 compared to Windows 10, so this is essential.
Step 3: Run Disk Cleanup and Enable Storage Sense – Remove Junk Files
A major reason for Windows 11 slowing down is a full disk. Speed drops when an SSD becomes 80% full.
Go to Settings > System > Storage, and turn on Storage Sense. Select Automatic cleanup – this will clear temporary files and empty the Recycle Bin.
Detailed Description:
- Open Disk Cleanup (search for it).
- Select the C: drive > Check “Temporary files,” “Thumbnails,” and “Downloads.”
- Click on “Clean up system files” to also perform a Windows Update cleanup.
My personal example: After removing 120GB of junk, file opening speeds doubled. Free Tool: Download Microsoft PC Manager (from Microsoft’s official website) – it cleans RAM and optimizes storage with just one click. It is completely free.
Comparison: Third-party tools like CCleaner cost $29 per year, whereas Microsoft PC Manager works at no cost. If your Windows 11 PC is running slowly, run Storage Sense daily.
Step 4: Malware Scan and Virus Check – Remove Hidden Enemies
Windows 11 often slows down due to viruses. Use Microsoft Defender.
Settings > Privacy & security > Windows Security > Virus & threat protection > Run a Quick scan. If in doubt, run a Full scan.
Extra Tip: Use the free version of Malwarebytes (for a one-time scan). I once discovered some PUPs (Potentially Unwanted Programs) that were consuming 40% of my CPU resources. After removing them, the issue of Windows 11 running slowly was reduced by 50%.
Edge case: Malware has a greater impact on low-end PCs (4GB RAM). Always keep real-time protection enabled.
Step 5: Change Power Settings – Turn On High Performance Mode
Windows 11 becomes slow due to Battery Saver mode.
Select Settings > System > Power & battery > Power mode > Best performance. It works even better if you keep the laptop plugged in.
Example: My laptop was in Balanced mode – the CPU was throttling. After switching to High Performance, multitasking became smooth.
Comparison: This effect was less pronounced in Windows 10, but the power plan is more sensitive in Windows 11. To unlock the Ultimate Performance plan, run powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 in the Command Prompt (in Admin mode).
Step 6: Disable Visual Effects and Animations – Best for Older PCs
If your PC is old, animations consume RAM.
Search for “Adjust the appearance and performance of Windows” > Select “Adjust for best performance.” Alternatively, manually uncheck “Animate windows” and “Fade effects.”
Neutral Tip: This makes the look feel a bit dated, but it significantly boosts performance. My 2018 laptop went from running sluggishly on Windows 11 to performing normally. For gamers, the Game Mode + this combo is perfect.
Step 7: RAM and SSD Upgrade – Hardware Fix
If a software fix doesn’t work, check the hardware.
8GB to 16GB RAM Upgrade: $40–80 (Check Kingston or Corsair). SSD (NVMe 500GB): $50–70.
Comparison: HDD vs. SSD – Windows 11 feels 3–4 times slower on an HDD. After installing an SSD, the boot time is just 10 seconds!
Edge Case: In ultrabooks, the RAM is soldered; in such instances, buying a new PC is the only option. However, it is easy to do on a desktop.
Step 8: Turn off Indexing and Notifications
Search Indexing consumes CPU resources. Go to Indexing Options > Modify > Uncheck User folders.
Disable Notifications: Settings > System > Notifications > Turn all off. Also, turn off Tips. This helps reduce the feeling that Windows 11 is running slowly.
Step 9: Use Microsoft PC Manager and Free Tools
This is an official free tool – Storage Clean, Startup Manager, and Health Check. Download from the Microsoft Store. Optimize with a single click.
Another free option: BleachBit (Open Source) – but use with caution.
Step 10: Advanced Tips – Virtual Memory, Clean Boot
Increase Virtual Memory: System Properties > Advanced > Performance Settings > Virtual memory > Custom size (RAM x 1.5).
Clean Boot: msconfig > Services > Hide Microsoft > Disable all. Test.
Enable HAGS (Hardware-accelerated GPU scheduling) for gaming PCs.
Windows 11 Slow vs. Windows 10: Comparison and Implications
Due to its abundance of animations and features, Windows 11 may feel 10–15% slower than Windows 10 – even on high-end hardware. However, this is improving with updates. The issue of sluggishness is more pronounced on low-end PCs. Implication: Battery life may decrease initially, but this is balanced out once performance is optimized.
