A cluttered desktop can make it difficult to find documents, shortcuts and frequently used applications. Start by reviewing the files and folders saved on your desktop and in your Downloads folder. Move important documents into clearly named folders, such as Work, Studies, Invoices or Personal Documents. Delete duplicate downloads and files you no longer need, but open unfamiliar files before deciding whether they are safe to remove. Remember that deleting a desktop shortcut does not normally uninstall the application it opens. Likewise, deleting a file from Downloads may permanently remove a document you still need, so review its contents carefully before cleaning up.

• Review desktop files. Move important documents into clearly named folders such as Work, Studies, Invoices or Personal Documents.
• Review the Downloads folder. Delete duplicate downloads and files you no longer need, but open unfamiliar files before removing them.
• Distinguish shortcuts from applications. Remember that deleting a desktop shortcut does not normally uninstall the application it opens.

When a computer's storage drive becomes nearly full, installing updates and saving new files can become more difficult. Reviewing available storage is a useful starting point before removing unnecessary data. On Windows 11, open Settings → System → Storage to see how storage space is being used. Depending on your Windows version, you may find options for temporary files, storage recommendations and automatic cleanup through Storage Sense. Review the categories before deleting anything. Temporary files and certain cached data may be safe to remove, but files in Downloads, Recycle Bin or other personal folders should be checked first. Avoid deleting unfamiliar system folders or files simply because they occupy space.

• Check available storage. Open Settings → System → Storage to see how much space remains and what is using it.
• Review temporary files. Temporary files and certain cached data may be safe to remove using Windows' built-in tools.
• Check personal folders first. Files in Downloads, Recycle Bin or other personal folders should be reviewed before deletion.
• Avoid deleting unfamiliar system files. Do not delete unfamiliar system folders simply because they occupy space.

Applications that you installed for a short-term project or no longer need can take up storage space and may receive updates or background tasks. Reviewing your installed software helps you understand what is on your computer. On Windows, open Settings → Apps → Installed apps and review the list. If you identify an application you no longer need, use the normal uninstall option provided by Windows or the application's official uninstaller. Be cautious with unfamiliar names, drivers, security tools and software that may be required by your employer or school. If you are unsure whether an application is essential, check with your IT support team before removing it.

• Review installed apps. Open Settings → Apps → Installed apps and review the list of software on your computer.
• Uninstall unnecessary applications. Use the normal uninstall option provided by Windows or the application's official uninstaller.
• Be cautious with essential software. Do not remove unfamiliar names, drivers, or security tools without checking with IT support first.

Some applications launch automatically when Windows starts. A long list of startup applications may increase the time it takes to reach your desktop and leave unnecessary programs running in the background. Open Task Manager → Startup apps to review the available options. Disable automatic startup only for applications you recognise and do not need immediately after signing in. Avoid disabling security software, essential device utilities or business applications without understanding their purpose. The goal is to reduce unnecessary startup activity, not to prevent important programs from functioning correctly.

• Review startup apps. Open Task Manager → Startup apps to see which applications launch automatically.
• Disable unnecessary startup programs. Disable only applications you recognise and do not need immediately after signing in.
• Keep essential software enabled. Avoid disabling security software, essential device utilities, or business applications.

Software updates can provide security fixes, reliability improvements and compatibility changes. A cleanup session is a good opportunity to check whether your computer has pending updates. Open Settings → Windows Update and check for available updates. Install appropriate updates and restart the computer when prompted. You should also update commonly used browsers and applications through their built-in update features or official websites. For business computers, follow your organisation's update policy before installing major upgrades. Keep the device connected to a reliable power source and avoid interrupting an update while it is in progress.

• Check for Windows updates. Open Settings → Windows Update and install appropriate updates.
• Update browsers and applications. Use built-in update features or official websites to keep your software current.
• Restart when prompted. Restart the computer when an update requires it, and avoid interrupting the process.
• Follow business IT policy. For work computers, follow your organisation's update policy before installing major upgrades.

A tidy computer still needs effective security protection. Review your antivirus or endpoint security software to make sure it is active and that its protection updates are current. On a personal Windows computer, open the Windows Security application and review the relevant protection status. Run a scan if appropriate, particularly if you have noticed unusual behaviour or recently downloaded a suspicious file. Do not install multiple antivirus products simply because they advertise extra protection. Conflicting security tools can cause problems, and unfamiliar "PC cleaner" applications may offer little benefit or introduce additional risks. Use trusted software and investigate genuine warnings rather than ignoring them.

• Review security status. Open Windows Security and confirm your antivirus or endpoint protection is active and up to date.
• Run a scan if needed. Run a scan if you have noticed unusual behaviour or recently downloaded a suspicious file.
• Avoid conflicting tools. Do not install multiple antivirus products or unfamiliar "PC cleaner" applications.
• Investigate genuine warnings. Use trusted software and investigate genuine security warnings rather than ignoring them.

Before making major changes to your computer, ensure that important documents, photographs and business files are backed up. A cleanup should make your information easier to manage, not put it at risk. Sort important files into folders with clear names and remove duplicate copies only after checking which version you need. If you use cloud storage or an external drive, confirm that the backup has completed and that you can access the saved files. For small businesses, consider whether essential records are covered by the organisation's backup policy. Important business data may require controlled access, encryption and a tested recovery process. Simply copying files to another location does not guarantee that a backup can be restored successfully.

• Back up important files. Ensure documents, photographs and business files are backed up to a trusted external drive or cloud service.
• Organise files into folders. Sort important files into folders with clear names and remove duplicates only after checking which version you need.
• Verify backup access. Confirm that the backup has completed and that you can actually access the saved files.
• Follow business backup policy. For small businesses, ensure essential records are covered by the organisation's backup and recovery policy.

Dust, fingerprints and everyday debris can accumulate on keyboards, screens and computer cases. Physical cleaning can help keep your workspace comfortable and prevent dirt from building up around ventilation openings. Before cleaning, shut down the computer and disconnect the power cable. Disconnect external accessories where appropriate. Use a soft, lint-free cloth for the exterior and follow the manufacturer's instructions for the screen, keyboard and other components. Avoid spraying liquids directly onto the computer, screen or keyboard. Do not use household cleaners, abrasive materials or excessive moisture unless the manufacturer specifically permits the product. For a laptop, be especially careful around the keyboard, ports and hinges. If you use a laptop, place it on a clean, stable surface and avoid blocking its ventilation openings during normal operation.

• Shut down and disconnect. Turn off the computer and disconnect the power cable and external accessories before cleaning.
• Use suitable materials. Use a soft, lint-free cloth and follow the manufacturer's instructions for each component.
• Avoid spraying liquids directly. Do not spray liquids onto the computer, screen or keyboard.
• Be careful with laptops. Take extra care around the keyboard, ports and hinges, and avoid blocking ventilation openings.

Desktop computers and laptops need adequate airflow to manage heat. Dust around vents can restrict airflow, so it is worth checking whether the openings are visibly blocked. For accessible exterior vents, follow the manufacturer's recommended cleaning method. Power the device off and disconnect it from power first. Do not push objects into vents or use a household vacuum directly on sensitive internal components. Opening a computer case to clean internal parts requires additional care. If the manufacturer permits user maintenance and you are comfortable with the procedure, follow its instructions. Otherwise, ask a qualified technician to clean the interior, particularly if the device is overheating or making unusual fan noises. Never open a power supply unit yourself. It can contain components that remain dangerous even after the computer has been unplugged.

• Check visible vents. Look for visible dust or blockage around ventilation openings.
• Power off first. Shut down the computer and disconnect it from power before cleaning accessible vents.
• Use safe cleaning methods. Do not push objects into vents or use a household vacuum on sensitive components.
• Seek help for internal cleaning. Ask a qualified technician to clean the interior if the device is overheating or making unusual noises.
• Never open the power supply. It can contain components that remain dangerous even after the computer has been unplugged.

Once you have finished the cleanup, restart the computer and check that everyday functions still work as expected. Open your usual applications, confirm that your internet connection is working and make sure important documents are accessible. Pay attention to unusual warning messages, unexpected shutdowns, repeated crashes or persistent overheating. A cleanup may improve organisation and free storage space, but it will not necessarily resolve hardware failures, malware infections or other underlying problems. If the computer remains unusually slow, investigate the specific cause instead of installing random optimisation tools. A qualified technician can help diagnose persistent issues that basic maintenance does not resolve.

• Restart the computer. Restart after the cleanup and check that everyday functions still work as expected.
• Test usual applications. Open your usual applications, confirm your internet connection works, and ensure documents are accessible.
• Watch for warning signs. Pay attention to unusual warning messages, unexpected shutdowns, repeated crashes or persistent overheating.
• Investigate persistent issues. If the computer remains unusually slow, investigate the specific cause rather than installing random optimisation tools.
