How To Fix A Slow Windows 11 PC

1. Restart and check for Windows updates

A restart clears temporary background processes. If the computer has not been restarted in several days, this is the easiest first step.

1. Save any open work.
2. Select Start, then Power, then Restart.
3. After the restart, open Settings and choose Windows Update.
4. Install available updates, then restart again if Windows asks.

If an update is stuck for a long time, avoid forcing the computer off repeatedly. Give it time, especially on older laptops.

2. Turn off unnecessary startup apps

Many programs start automatically when Windows opens. Too many startup apps can make an otherwise healthy computer feel slow.

1. Right-click the Start button and choose Task Manager.
2. Select Startup apps.
3. Look for apps you recognize but do not need every time the computer starts.
4. Select the app and choose Disable.

Do not disable security software or system items you do not understand.

3. Free up storage space

Windows needs free space to update and manage temporary files. A nearly full drive can slow the system down.

1. Open Settings.
2. Choose System, then Storage.
3. Review temporary files, downloads, and large categories.
4. Remove only files you understand and no longer need.

Before deleting personal files, consider copying important photos and documents to an external drive or cloud backup.

4. Check browser tabs and extensions

A slow computer is sometimes a slow browser. Too many open tabs, unwanted extensions, or notification permissions can use memory and attention.

• Close tabs you are not using.
• Remove extensions you do not recognize.
• Turn off notifications from websites you do not trust.
• Restart the browser after making changes.

5. Run built-in security checks

Windows Security is included with Windows 11 and can scan for many common threats.

1. Open Start and search for Windows Security.
2. Choose Virus & threat protection.
3. Select Quick scan.
4. If Windows recommends action, read the message carefully before continuing.

6. When to ask for help

If the computer is still extremely slow, makes unusual noises, overheats, shows drive errors, or contains important business or family files, consider asking a qualified technician to review it. Hardware age, failing storage, and low memory can also cause poor performance.
