I have helped a lot of friends with this. Their computers are fine. But games run bad. Why? Windows gets in the way. Windows does a hundred little things while you try to play. Most people do not know this.
You do not need to be a computer person to fix it. You just need to follow what I write here. I will show you each thing one by one.
Transform Your Windows PC into a Gaming Powerhouse
First Thing First
Before you do anything else. Check if Windows has updates. Go to Start. Type update. Click the thing that says check for updates. Let it finish. Then restart. Do not skip this. I have seen people skip this and then wonder how to optimize windows for gaming.
Also close your browser. Close Spotify. Close Discord. Close everything except this guide. You want nothing else running.

Turn On Game Mode
Windows has this thing called Game Mode. Microsoft made it for exactly what you want. It tells your computer to stop messing around and give power to your game.
Go to Start. Type game mode. Click Game Mode settings. There is a switch. Turn it on. That is it. Now Windows knows your game is important.
I know someone who only did this one thing and their game stopped stuttering. Not always. But sometimes one step is enough.
Power Plan Change
Windows has different ways to use power. One way saves electricity. That is bad for games. You want the way that gives everything to your computer.
Open Control Panel. You can type it in Start. Then click Hardware and Sound. Then Power Options. Look for High performance. Click it. If you do not see it, click show additional plans.
Some laptops have their own power software. Check that too. Make sure it is set to performance not battery saver.
Stop Background Apps
So many apps run without you knowing. You install something and it says oh I will just run in the background. Next thing you know ten things are running. Eating your memory. Eating your processor.
Go to Start. Type background apps. Click Background app settings. There is a master switch at the top. Turn it off. Yes off. All of them.
Then go through the list. Keep only what you really need. For most people that is nothing. Maybe your antivirus. Thats it.
Visual Stuff That Does Nothing For Games
Windows looks fancy. It has shadows and animations and transparent bars. Looks nice. But your game does not care about nice. Your game wants speed.
Go to Start. Type advanced system settings. Click it. Then click the Advanced tab. Then under Performance click Settings.
You will see a list of checkboxes. Just click adjust for best performance. Windows will look like Windows 95. Ugly but fast. Or you can click custom and keep a few things. I keep smooth edges of screen fonts because ugly text hurts my eyes. But if you want max speed turn everything off.
Stop Windows From Restarting While You Game
This is the worst. You are playing. Finally got into a match. Then Windows says hey time to restart for updates. And your game is gone.
You can stop this.
Go to Start. Type Windows Update. Click Windows Update settings. Then click Advanced options. Turn on notify me when a restart is required.
Then go back and click Active hours. Tell Windows when you usually play. If you play from 7 PM to midnight put that in. Windows will not restart during those hours.
Turn Off Xbox Stuff
- Windows has Xbox features built in. Even if you do not own an Xbox. Even if you never play Xbox games. These features record your gameplay in the background. They use power.
- Go to Start. Type Xbox Game Bar. Click Xbox Game Bar settings. Turn the switch off.
- Then go to Start again. Type captures. Turn off record in the background while I am playing.
- Now Windows is not secretly recording you.
Update Your Graphics Driver
- This one matters a lot. The driver is the thing that lets your game talk to your graphics card. Old driver means slow game. New driver means fast game.
- If you have NVIDIA. Go to their website. Download the latest. When you install click custom installation. Then check clean installation.
- If you have AMD. Go to their website. Download. Install. Choose factory reset option.
- If you have Intel. Same thing. Their website.
- After you install restart your computer. Do not skip the restart.
Turn Off Tips And Tricks
Windows likes to give you suggestions. Hey try this. Hey finish setting up your computer. Hey did you know. No. Stop. I am playing a game. Go to Start. Type notifications. Click Notification settings. Look for get tips tricks and suggestions. Turn it off. Now Windows will shut up.
Clean Your Hard Drive
Full hard drive makes everything slow. Games need free space. They put temporary files there. They need room to breathe. Go to Start. Type Disk Cleanup. Open it. Pick your main drive usually C. Let it scan. Then check every box. Especially temporary files and recycle bin and delivery optimization files.
- Click OK. Then click delete files.
- Then click clean up system files. Do the same thing again.
Check For Hard Drive Errors
- Sometimes your hard drive gets small errors. These errors make things slow. Windows can fix them.
- Go to Start. Type cmd. Right click on Command Prompt. Click run as administrator.
- A black box opens. Type chkdsk /f. Press Enter. It will ask if you want to check next restart. Press Y. Press Enter. Restart your computer.
- Let it run. It takes a few minutes.
Stop Programs That Start Automatically
So many programs put themselves in startup. You do not ask them to. They just do it. Every time you turn on your computer they start running. Press Ctrl Shift Esc together. That opens Task Manager. Click the Startup tab. You will see a list. Look at the Status column. Anything that says Enabled you can probably disable. Right click it. Click Disable. You can still open these programs later. They just will not start by themselves anymore.

Turn Off Search Indexing
Windows keeps a list of all your files so you can search fast. That is nice. But it also keeps updating that list while you play games. That uses your hard drive.
You can turn it off.
Go to Start. Type Services. Click Services. Scroll down to Windows Search. Right click it. Click Properties. Next to Startup type click the dropdown. Select Disabled. Then click Stop. Then OK.
Your search will be slower when you look for files. But your game will be faster. Worth it.
Fix The Page File
The page file is space on your hard drive that Windows uses as fake memory. When your real memory runs out Windows uses this. If it is too small your game slows down.
Go to Start. Type advanced system settings. Click it. Click Advanced tab. Under Performance click Settings. Click Advanced tab again. Under Virtual memory click Change.
Uncheck automatically manage paging file size. Click your main drive. Click custom size.
If you have 8GB of memory type 8000 for initial and 16000 for max. If you have 16GB type 16000 and 32000.
Click Set. Click OK. Restart.
Turn Off Mouse Acceleration
Mouse acceleration makes your mouse move faster when you move it fast. In games that is terrible. You want the same movement every time.
Go to Start. Type mouse settings. Click it. Click additional mouse options. Click Pointer Options tab. Uncheck enhance pointer precision. Click OK.
Now your mouse moves exactly how to optimize windows for gaming. No tricks.
Keep Free Space On Your Drive
This is simple. Do not fill your hard drive. Leave at least 15 percent free. If your drive is 90 percent full your computer will feel like garbage.
Open File Explorer. Click This PC. Look at your main drive. If the bar is almost full delete stuff. Old games you do not play. Old downloads. Big videos you already watched.
Test If Anything Got Better
Play your game for ten minutes. Does it feel different? Less stuttering? Faster loading?
You can do a before and after. Play for five minutes before you change anything. Write down how it feels. Then change everything. Play again. Most people notice a big difference.
Do Not Use Registry Cleaners
I have to say this because people ask. Do not use registry cleaners. They do not help. They break things. I have seen computers die because someone ran a registry cleaner they downloaded from some website. Just do not.
Do Not Buy Game Boosters
Same thing here. Game booster software is mostly garbage. They put ads on your computer. Some of them are straight up malware. The steps I gave you do the same thing for free and they actually work.
When To Do This Again?
You do not need to do this every week. Do it once. Then do it again after a big Windows update. Big updates happen two or three times a year. Windows will tell you.
Also do it again if you get a new graphics card or a new hard drive.
What If Your Game Is Still Slow?
Look I have to be honest. These steps help a lot. But they cannot turn a weak computer into a gaming computer. If your processor is old or you only have 4GB of memory or you do not have a real graphics card then no amount of Windows tweaking will save you.
Check your computer parts. You need at least a Core i5 or Ryzen 5. At least 8GB of memory. A dedicated graphics card not the built in kind.
If you have those things and the game is still slow then these steps will help. If you do not have those things then you need new parts or a new computer.
Conclusion
Do not do all these steps at once if you do not have time. Do three steps. Play a game. Do three more steps. Play another game. You will feel the improvement as you go.
The most important steps are Game Mode. Power plan. Background apps. Start with those.
