A slow computer does not always mean an old computer. Most Windows 11 PCs in Pakistan slow down because of startup apps, a nearly full disk, visual effects and ignored updates — not because the hardware is finished. Before paying a repair shop, try these fifteen free fixes in order.
The Biggest Speed Fixes First
1. Stop apps from opening at startup
This is the number one cause of slow boot times. Press Ctrl + Shift + Esc to open Task Manager, click Startup apps, and disable everything you do not need at startup — Spotify, Adobe updaters and game launchers can all wait. Keep only your antivirus enabled.
2. Free up disk space
Go to Settings > System > Storage, click Temporary files, and remove Windows Update files, thumbnails and the Recycle Bin. Keep at least 15–20 GB free on your C: drive.
3. Turn on Storage Sense
In the same Storage settings, switch on Storage Sense and set it to run every month. It auto-deletes temporary files, so your disk never fills up again.
4. Uninstall programs you never use
Open Settings > Apps > Installed apps, sort by size, and remove old games, toolbars, trial antivirus software and programs you forgot about.
Settings That Make Windows Feel Faster
5. Turn off visual effects
Go to Settings > Accessibility > Visual effects and switch off Transparency effects and Animation effects. For a bigger gain, search Windows for “Adjust the appearance and performance of Windows” and choose Adjust for best performance.
6. Set the power mode to Best performance
Go to Settings > System > Power and battery and set Power mode to Best performance. On a laptop, use it plugged in; a desktop PC on a UPS should simply stay on Best performance.
7. Disable background apps you do not need
Open Settings > Apps > Installed apps, click the three dots next to an app, choose Advanced options, and set Background apps permissions to Never for apps that need not run when closed.
8. Turn off Game Bar recording if you do not game
If you never record gameplay, go to Settings > Gaming and switch off Game Bar and background recording in Captures.
Keep Windows Clean and Healthy
9. Install Windows updates
Go to Settings > Windows Update, click Check for updates, and open Advanced options > Optional updates to install newer drivers listed there — especially graphics drivers.
10. Run a full malware scan
Malware is a common hidden cause of sudden slowdowns, especially after installing software from unofficial websites. Open Windows Security > Virus and threat protection, click Scan options, and run a Full scan.
11. Check your disk for errors
Press the Windows key, type cmd, right-click Command Prompt, choose Run as administrator, type chkdsk /f and press Enter. Windows will check and repair disk errors on the next restart.
12. Restart properly instead of only shutting down
Because of Fast Startup, Shut down does not fully refresh Windows — Restart does. One proper restart can clear stuck processes and finish pending updates — make it a weekly habit.
Last Steps: Small Upgrades That Transform an Old PC
13. Add more RAM if you have only 4 GB
In Task Manager’s Performance tab, if your PC has 4 GB of RAM and usage sits above 80%, upgrading to 8 GB is the cheapest real performance jump.
14. Replace the hard disk with an SSD
If your PC still runs on a traditional hard disk (HDD), moving Windows to even a basic SSD is the single biggest upgrade possible — boot times drop from minutes to seconds, for far less than a new computer.
15. Reset Windows only if everything else fails
Back up your files and use Settings > System > Recovery > Reset PC > Keep my files. This reinstalls clean Windows while preserving your documents.
Conclusion
Start with startup apps, free disk space and Storage Sense, then adjust visual effects and power mode, and finish with updates and a malware scan. These free fixes solve most cases; only then consider RAM and an SSD.
FAQ
Why is my Windows 11 PC slow after an update?
Updates run indexing in the background for a few hours. Leave the PC on for an evening; if still slow the next day, check Task Manager’s Processes tab for the top CPU or disk user.
How much free space does Windows 11 need?
Keep at least 15–20 GB free on the C: drive. Below that, Windows cannot install updates properly, and everything crawls.
Will turning off visual effects really help?
On PCs with integrated graphics or 4–8 GB of RAM, yes — menus open instantly and the system feels lighter.
Is an SSD or RAM the better first upgrade?
If your PC still has a hard disk, the SSD comes first. If you already have an SSD but only 4 GB of RAM, add RAM instead.
