How to Speed Up a Slow Windows 11 PC (10 Proven Tips)

 

Is your Windows 11 PC crawling like a snail? You are not alone. Millions of users report their computers slowing down over time — and in most cases, the fix does not require buying new hardware. With a few smart tweaks, you can dramatically speed up your PC in under an hour. 

Why Does Windows 11 Slow Down? 

Windows 11 slows down due to too many startup programs, bloated temporary files, outdated drivers, low RAM availability, or a fragmented hard drive. Every one of these issues has a free solution built right into Windows itself. 

Tip 1 — Disable Startup Programs 

Press Ctrl + Shift + Esc to open Task Manager, then click the Startup tab. Right-click any program you do not need at startup and select Disable. Common culprits include Spotify, Discord, OneDrive, and Teams. 

Tip 2 — Free Up Disk Space with Storage Sense 

Go to Settings → System → Storage → Storage Sense. Turn it on and run it manually. This removes temporary files, old downloads, and Windows Update leftovers that waste gigabytes. 

Tip 3 — Adjust Power Plan to High Performance 

Go to Control Panel → Power Options and switch from Balanced to High Performance. This unlocks your CPU's full potential, especially on laptops. 

Tip 4 — Disable Visual Effects 

Search for Adjust the appearance and performance of Windows. Select Adjust for best performance. This disables animations that slow down older machines significantly. 

Tip 5 — Update Your Drivers 

Outdated graphics or chipset drivers cause significant slowdowns. Open Device Manager, right-click your display adapter, and select Update driver. Restart after updating. 

Tip 6 — Scan for Malware 

Open Windows Security → Virus and threat protection → Quick scan. Malware quietly consumes RAM and CPU in the background without you noticing. 

Tip 7 — Increase Virtual Memory

 Search for Adjust the appearance and performance of Windows → Advanced → Change virtual memory. Set minimum 1.5x your RAM, maximum 3x your RAM. 

Tip 8 — Defragment Your HDD 

If you have a traditional hard disk (not an SSD), open Defragment and Optimize Drives and run optimization. Never defragment an SSD — it reduces lifespan. 

Tip 9 — Restart Regularly 

A simple restart clears RAM and applies pending updates. If you never restart, memory leaks accumulate and slow everything down over days. 

Tip 10 — Add More RAM 

If your PC has 4GB or less, upgrading to 8GB or 16GB is the single most impactful hardware change. RAM prices are low, and installation takes 15 minutes.
