How to perform repair install in Windows 11?

There are several ways Microsoft gives you in order to repair a malfunctioning Windows device – from things like System Restore or Windows reset to repair-installing or fully reinstalling. While the solution depends on the situation at hand and personal preference, performing in-place upgrade is the most common tactic used.

Why choose repair-installing?

There are several scenarios where repair-installing Windows can be beneficial. If your system files are corrupted and causing errors, or if you're facing issues with system updates, a repair installation can resolve these problems. It is also useful for fixing minor performance issues and addressing specific OS glitches. Unlike a complete reinstallation, this method keeps all your personal files and installed applications intact, saving you time and effort.

When to consider a repair installation

When ordinary troubleshooting fails to resolve persistent issues, you could consider about having a repair installation done. A repair installation may be necessary, for example, if corrupted system files cannot be repaired using the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) commands, or if Windows updates are not successful even after utilizing the Windows Update Troubleshooter. If previous performance adjustments haven't improved the overall speed of your machine, this is also a viable choice.

Preparing for it

Before starting a repair installation, it's important to get adequately prepared. While the process should keep your data intact, you should still back up your important files – just in case. This ensures that in case anything goes wrong, your data remains safe.

You'll need to download the Windows 11 ISO file or use the Media Creation Tool to get the installation media. Having these ready beforehand will make the process easier. Additionally, you should also disconnect any unnecessary peripherals (such as printers and external drives), and uninstall third-party security software, if applicable.

The process and what to expect

During a repair installation, you'll essentially be performing an upgrade over your current system. In order to repair any damage or errors, this procedure replaces the essential system files with new copies from the installation ISO. You won't have to reinstall anything or lose any data because your installed apps, personal files, and settings are all kept exactly as they are.

The repair installation can take some time, depending on the speed of your computer and the extent of the issues being resolved. After the process, your system should be more stable and perform better, with the problems that prompted the repair installation resolved.
