  • How to Free Up Space on a Windows 11 PC

    Running out of storage can make Windows harder to use and leave less room for updates. These steps help you free space without deleting important files blindly.

    1. Check what is using your storage

    1. Open Settings → System → Storage.
    2. Review the categories using the most space.
    3. Open the largest categories to see what can safely be removed.

    2. Remove temporary files

    1. In Storage, open Temporary files.
    2. Review the list carefully.
    3. Select files you no longer need.
    4. Choose Remove files.

    3. Uninstall apps you no longer use

    1. Open Settings → Apps → Installed apps.
    2. Sort by size when useful.
    3. Uninstall programs you recognize and no longer need.

    4. Move large personal files

    Move large videos, photos, installers, or project files to another drive or trusted cloud storage after confirming you have a backup.

    5. Empty the Recycle Bin

    Open the Recycle Bin and make sure you do not need anything inside it. Then empty it to actually reclaim the space.

    Still low on space?

    Use the Storage settings to identify the largest category before deleting anything manually. This reduces the risk of removing files Windows or your applications need.

  • How to Fix High CPU Usage in Windows 11

    High CPU usage can make Windows feel slow and keep your fans running. The first step is to find the process using the CPU.

    1. Check CPU usage in Task Manager

    1. Press Ctrl + Shift + Esc.
    2. Open Processes.
    3. Click the CPU column to sort it.
    4. Watch for a process that stays high instead of ending it immediately.

    2. Check the app using the CPU

    If one normal application stays near the top, update it or close it and test again. Do not end Windows system processes just because they use CPU.

    3. Reduce unnecessary startup apps

    1. In Task Manager, open Startup apps.
    2. Disable programs you recognize and do not need at sign-in.
    3. Restart Windows.

    4. Scan for unwanted software

    1. Open Windows Security.
    2. Run a scan.
    3. Review detections before taking action.

    5. Check temperatures and cooling

    If CPU usage is normal but temperatures remain high, check airflow, dust, and cooling. High temperature is not always caused by high CPU usage.

    Still high?

    Identify whether the CPU load comes from Windows, one app, a background service, or security software. Changing one thing at a time makes the cause easier to identify.

    How to Fix a Slow Windows 11 PC

    A slow Windows 11 PC can have several causes. Start with the quick checks below and work down the list until performance improves.

    1. Check what is using CPU, memory, and disk

    1. Press Ctrl + Shift + Esc to open Task Manager.
    2. On Processes, sort by CPU, Memory, and Disk.
    3. Look for an app that stays unusually high for several minutes.
    4. Close only programs you recognize and do not need.

    2. Reduce unnecessary startup apps

    1. Open Task Manager → Startup apps.
    2. Sort by Startup impact.
    3. Disable apps you recognize but do not need to launch automatically.
    4. Restart Windows and test again.

    3. Free up storage space

    1. Open Settings → System → Storage.
    2. Review temporary files and large categories.
    3. Remove files you no longer need.
    4. Keep enough free space for Windows and your applications.

    4. Install Windows and driver updates

    1. Open Settings → Windows Update.
    2. Install available updates.
    3. Check your PC or hardware manufacturer’s support page for important driver updates.
    4. Restart the PC.

    5. Check for unwanted software

    1. Open Windows Security.
    2. Run a scan.
    3. Review any detections before removing software.

    6. Repair system files

    1. Open Windows Terminal (Administrator).
    2. Run DISM /Online /Cleanup-Image /RestoreHealth.
    3. Then run sfc /scannow.
    4. Restart Windows.

    Still slow?

    Check whether the slowdown happens only in one app or across Windows. That distinction can help narrow down whether the problem is the application, storage, memory, drivers, or Windows itself.
