A factory reset can remove apps, settings and personal data. Here’s how to choose the right reset option, protect your files and get Windows updated afterwards.
Factory resetting Windows 11 is often the last step in troubleshooting a stubborn PC, but Microsoft treats it as one of the most disruptive recovery options. The process reinstalls Windows, and it gives users a choice between preserving personal files or wiping the machine completely. Microsoft’s current guidance also allows either a Cloud download, which fetches a fresh copy of Windows, or a Local reinstall, which uses files already on the device. If the computer will not boot normally, the same reset can be started from the Windows Recovery Environment. According to Microsoft, users should back up important data and have the BitLocker recovery key ready before they begin.
The practical first step is to protect anything that matters. Microsoft’s Windows Backup tool can save selected folders, including Desktop, Documents, Pictures, Videos and Music, to a Microsoft account and OneDrive. A free account includes 5 GB of storage, so larger libraries may need additional space or an external drive. Microsoft also notes that Windows activation is usually tied to the device through a digital licence, which means the same edition of Windows can normally be reinstalled without entering a product key again. If the machine is encrypted with BitLocker or Device Encryption, the 48-digit recovery key should be found in advance, because Microsoft says it cannot recreate a lost key.
For most users, the choice comes down to two paths. Keep my files removes apps and system settings, but leaves personal files in place. Remove everything deletes personal files as well as apps and settings. Microsoft also offers a Clean data option, which makes deleted information harder to recover and is intended for devices being sold, donated or recycled. However, the company says this consumer erasure feature does not meet government or industry sanitisation standards, so organisations handling sensitive records should use approved disposal methods instead. Microsoft’s current recovery guidance also points to lighter fixes first, including troubleshooters, uninstalling recent updates, reinstalling Windows while keeping files, apps and settings, Point-in-time restore on supported versions, and Cloud rebuild when a reset is not enough.
If Windows still opens, the reset can be launched through Settings under System and Recovery. From there, users select Reset this PC, choose whether to keep or remove files, and then decide between Cloud download and Local reinstall. Microsoft warns that the screen may stay black for more than 15 minutes during the process, so it should not be interrupted. If Windows will not start, the same reset can be reached through WinRE by holding Shift while selecting Restart from the sign-in screen, using Advanced startup in Settings, or forcing Automatic Repair after repeated failed boots. In each case, BitLocker protection may trigger a key prompt before the reset continues.
Once the reset finishes, the machine should be updated immediately. Microsoft says a Local reinstall may not include the latest patches, which makes Windows Update the next essential step. That matters because Microsoft’s lifecycle page shows that Windows 11 version 25H2 is supported until 12 October 2027, while version 26H2 is scheduled to receive updates until 10 October 2028. For older or damaged installations, a Cloud download can be a useful way to land on a current build without relying on local system files. If the reset is being done before sale or disposal, signing out of apps, checking the device list on the Microsoft account and switching off Find My Device are also sensible final checks.
