Movian SecurityHow to Reset Windows 10 Without Losing Personal Files
A Windows 10 reset can restore a slow, unstable, or infected computer without deleting documents, photos, music, and other files stored in your user folders. The process reinstalls Windows and removes applications, system changes, and many settings that may be causing problems.
The safest option for most people is Reset this PC > Keep my files. This is different from a full clean installation, which erases the Windows drive. Even when personal files are intended to remain, a current backup is essential because hardware faults, encryption issues, interrupted updates, or incorrect choices can still cause data loss.
This guide explains how to prepare a Windows 10 computer, choose the appropriate reset method, complete the reset, and restore everyday functionality. It also covers practical concerns for Australian users, including NBN connectivity, power interruptions, and common software used by households and small businesses.
What the keep my files option preserves
The “Keep my files” reset normally preserves content in folders such as Documents, Pictures, Videos, Music, and Desktop under your Windows user account. Files stored on other internal partitions or external drives are usually left untouched, provided you do not select an option that removes everything or formats those locations.
The reset removes installed desktop programs, many Microsoft Store apps, custom drivers, system preferences, and changes made to Windows settings. You should expect to reinstall software such as Microsoft 365, Adobe applications, accounting programs, browsers, games, VPN clients, printers, and specialist business tools.
A reset is useful when Windows is repeatedly crashing, starting slowly, displaying corrupted system errors, or behaving strangely after a failed update. It may also help after malware removal, although a serious infection can require a more thorough offline scan or a complete clean installation.
Back up important data before resetting
Copy essential files to an external USB hard drive, a trusted network location, or a cloud service such as OneDrive. Open several copied files to confirm that the backup works. Pay special attention to tax records, family photos, browser bookmarks, email archives, saved games, password databases, and files stored outside the standard Windows folders.
Check folders such as Downloads, shared folders, and folders created directly on the C: drive. Export Outlook data if the computer uses a local PST file, and record email account settings where necessary. If you use accounting software or a business application, follow its own backup procedure because some databases are not safely copied while the program is open.
Make sure you know your Microsoft account details and licences for paid software. If the device uses BitLocker or another form of drive encryption, save the recovery key in a secure location. Connect the computer to mains power during the reset; this matters particularly for laptops used in areas where a brief outage can interrupt a long operation.
Choose the reset source carefully
Windows 10 offers a choice between reinstalling from local files and downloading a fresh Windows image from Microsoft. The best choice depends on the condition of the existing installation and the reliability of your internet connection.
| Reset choice | Best suited to | Internet requirement | Main consideration |
|---|---|---|---|
| Local reinstall | A stable Windows installation with damaged settings or unwanted software | Low | Uses files already stored on the computer |
| Cloud download | Corrupted or missing Windows installation files | High | Downloads several gigabytes and may take longer |
| Keep my files | Problems caused by software, settings, or system corruption | Moderate or low | Removes applications and system customisation |
| Remove everything | Preparing a computer for resale or dealing with severe compromise | Moderate or low | Deletes personal data and requires a complete backup |
A local reinstall is often quicker when Windows system files are still healthy. Cloud download can be more reliable when those files are damaged, although an NBN connection in a busy household may slow the process if other people are streaming or working online.
Do not choose “Remove everything” simply because the computer is slow. That option is intended for a full wipe, such as before selling a computer in Sydney, Brisbane, Perth, or elsewhere in Australia. For a repair reset that retains personal data, select “Keep my files” and read each confirmation screen carefully.
Run the Windows 10 reset
Open Settings, select Update & Security, choose Recovery, and find Reset this PC. Select Get started, then choose Keep my files. Windows will display a list of applications it intends to remove. Save or photograph this list so you know what needs to be reinstalled.
Choose Cloud download or Local reinstall, review the additional settings, and select Next. The final screen should clearly state whether personal files will be kept. Begin the reset only after checking that the correct option is selected and that the computer is connected to power.
The computer may restart several times and remain on a progress screen for an extended period. Do not force it to shut down. When the Windows setup screens appear, select your region, keyboard layout, network, and account preferences. Australian users should check that the region is set to Australia so date formats, keyboard behaviour, currency, and regional settings match local use.
Restore applications and essential settings
After signing in, open File Explorer and check your Documents, Pictures, Desktop, and other important folders. Confirm that files open correctly before deleting the backup. If files are missing, stop using the computer and recover them from the external or cloud backup rather than creating new data on the drive.
Run Windows Update repeatedly until no important updates remain, restarting when prompted. Install current chipset, graphics, network, and printer drivers from the computer manufacturer or Microsoft. Reconnect printers and scanners, especially multifunction devices commonly used for home offices and small businesses.
Reinstall applications from official websites or trusted Microsoft sources. Restore browser bookmarks and extensions, reconnect OneDrive or another cloud account, and configure Outlook email. Avoid downloading several “driver updater” or “PC cleaner” utilities, as aggressive tools can create fresh instability or bundle unwanted software.
Security settings deserve attention after a reset. Confirm that Microsoft Defender is active, firewall protection is enabled, and Windows Update is working. Change passwords if the reset followed a suspected infection, and enable multi-factor authentication for email, banking, and cloud storage. This is particularly important on computers used for online banking, myGov, Medicare, or business payments.
When a reset does not fix the problem
A Windows reset addresses software and operating system problems, but it cannot repair a failing hard drive, defective memory, overheating processor, damaged charging system, or unreliable power supply. If the computer remains slow after a clean reset, check drive health, available storage, temperatures, startup programs, and memory usage.
Persistent blue screens, random shutdowns, clicking noises from a hard drive, or repeated file corruption indicate a possible hardware fault. An older computer with a mechanical hard drive may benefit more from an SSD upgrade and additional RAM than from repeated resets. Hardware changes should be planned around a verified backup.
A reset can also fail when the Windows recovery environment is damaged, storage is nearly full, or encryption recovery information is unavailable. In those cases, a technician can assess the drive, preserve data, remove malware safely, and perform a clean Windows installation when necessary. A professional repair service is especially useful when the computer contains irreplaceable files or supports a home business.
Once the system has been updated, secured, and tested, create a fresh backup image or file-based backup schedule. Keeping current copies means the next Windows fault can be handled quickly without placing personal data at unnecessary risk.
