How to Use Windows 10 Pro Cleanup Recommendations

A Windows 10 Pro computer can gradually fill with temporary files, old update packages, unused applications, browser data and forgotten items in the Downloads folder. When free space becomes scarce, the system may feel slower, updates can fail, and everyday tasks such as opening photos or saving documents become less reliable.

Windows includes built-in storage tools that help identify removable files without requiring a third-party cleaner. Depending on your Windows 10 build, the relevant page may be called Cleanup recommendations, Temporary files, or Storage settings. The names can vary after feature updates, but the basic process remains similar.

This guide explains how to review each category safely, remove unnecessary data, configure Storage Sense and avoid deleting files that you may still need. The steps suit home users, students and small businesses across Australia, including people using compact laptops in Sydney or Melbourne where a 128 GB solid-state drive can fill quickly.

Open Windows Storage And Cleanup Tools

Start by selecting Start, opening Settings, and choosing System. Select Storage in the left-hand menu. Windows will calculate how much space is being used by apps, documents, pictures, temporary files, mail and other categories. The first scan can take several minutes on an older hard disk.

If your installation shows Cleanup recommendations, open it to see groups such as temporary files, large or unused files, files synced to the cloud and unused apps. If that option is missing, select Temporary files instead. Windows 10 editions and builds do not all display the same labels, so the absence of the recommendations page does not mean that cleanup tools are unavailable.

Review the storage summary before selecting anything. A drive with only a few gigabytes available may need immediate attention, while a drive with 20 or 30 GB free may only require routine maintenance. Avoid repeatedly pressing refresh while Windows is calculating categories, as the scan may take longer when the disk contains many files.

You can also open File Explorer, select This PC, and check the free space shown beneath the Windows drive, normally labelled C:. This gives you a quick way to confirm whether cleanup has made a meaningful difference.

Review Temporary Files Carefully

The Temporary files screen normally lists items such as temporary installation files, Windows upgrade logs, thumbnail caches, Delivery Optimisation files, DirectX shader cache and the Recycle Bin. Tick only the categories you understand, then read the estimated size before choosing Remove files.

Temporary installation files and update cleanup files are usually safe to remove after Windows has installed an update successfully. Delivery Optimisation files are cached update fragments that Windows may share with other devices or use during future updates. Removing them does not uninstall Windows, although they may be downloaded again later.

The Recycle Bin requires extra care. Removing its contents permanently deletes items that are still recoverable through the bin. Open the Recycle Bin from the desktop and restore anything important before cleaning it. The same principle applies to Downloads: Windows may identify old installers and archives, but it cannot tell whether a file is still needed for tax records, work or study.

The Previous Windows installation or Windows.old category can occupy many gigabytes after a major upgrade. Delete it only when the current installation is stable and you are certain you will not need to return to the previous version. Once removed, the built-in rollback option may no longer be available.

Remove Unused Apps And Large Files

Cleanup recommendations may identify applications that have not been used recently. Treat this as a suggestion rather than an automatic instruction. A program used once a year, such as accounting software or a specialist printer utility, may still be valuable. Check the app name, publisher and last-used information before uninstalling it.

For a fuller list, go to Settings > Apps > Apps & features. Sort the list by size and remove software you recognise and no longer need. Avoid uninstalling hardware drivers, Microsoft components, antivirus tools or utilities supplied by your computer manufacturer unless you know their purpose. If an application is unfamiliar, search for its publisher and check whether another program depends on it.

Large files deserve a manual review. In File Explorer, open folders such as Downloads, Videos and Pictures, then select View > Details and sort by size. Move personal media to an external drive or a trusted cloud service before deleting it. Australians using NBN services may have high or unlimited data allowances, but uploading hundreds of gigabytes can still take considerable time, especially on plans with slower upload speeds.

Do not confuse free space with a backup. Moving a family photo library from the internal drive to one portable disk protects the computer from filling up, but it does not protect those files if the disk fails. Keep a second copy in another location or use a reputable backup service. Check that files open correctly before removing the original copy.

Use Storage Sense For Routine Maintenance

Storage Sense automates selected cleanup tasks. Open Settings > System > Storage, turn on Storage Sense, and select Configure Storage Sense or run it now. You can choose when Windows should run it, such as during low disk space, every day, every week or every month.

The settings normally control temporary file removal, Recycle Bin contents and files in the Downloads folder. The Downloads option deserves caution because it can remove files that have not been opened for a chosen period. Leave it disabled if Downloads contains invoices, installers, schoolwork or documents that are not stored elsewhere.

Storage Sense can manage locally available cloud files when a supported cloud provider is configured. An online-only copy can save disk space, but opening it later requires an internet connection. This distinction matters when travelling through areas with unreliable mobile coverage or when working away from a home NBN connection.

Run the tool manually after changing its settings by selecting Clean now. Watch the free-space figure in File Explorer afterwards. If the result is smaller than expected, Windows may still be using space for restore points, hibernation, virtual memory or personal files that Storage Sense does not remove.

Protect The System Before Deleting Data

Before a major cleanup, save open documents and create a backup of irreplaceable files. A restore point can help with some configuration problems, but it is not a replacement for backing up photos, videos and documents. If you are removing Windows.old or a large group of personal files, consider creating a restore point through Control Panel > System > System protection.

A recovery plan is especially useful before making installation changes. If the computer becomes unbootable, a prepared USB can provide access to repair and reinstall tools. When creating installation media, follow this bootable USB guide and use a reliable USB drive. Retailers such as Officeworks and other Australian computer shops commonly stock suitable 16 GB or 32 GB drives, but the drive will be erased during the creation process.

Personal information needs special handling. The Australian Privacy Act 1988 and the Australian Privacy Principles are relevant when businesses store or dispose of personal information belonging to customers or employees. Simply placing confidential files in the Recycle Bin is not enough when a computer is being sold or passed on. Use an approved secure-erasure process, remove accounts, and follow your organisation’s retention policy.

For old computers, do not place unwanted electronics in a normal household rubbish bin. Use an Australian e-waste collection point or a retailer recycling programme that accepts computers and accessories. Before disposal, sign out of Microsoft and cloud accounts, remove USB devices, reset the PC and confirm that sensitive data is no longer accessible.

Windows 10 reached the end of standard support on 14 October 2025, including in Australia. Cleanup tools still work, but they do not provide security updates. Check whether your computer supports Windows 11, whether an eligible Extended Security Update option applies, or whether replacing an ageing device is the safer long-term choice. Freeing space can improve maintenance, but it cannot extend Microsoft’s normal support period.

Review Windows 10 Pro’s storage recommendations once a month, then use manual checks for Downloads, cloud folders and large personal files. A few minutes of review can prevent accidental deletion and keep enough room available for updates. Use the built-in tools first, verify every category, and keep a separate backup before removing anything important.
