About this tag
Windows repair on WindowsForum.com covers the built-in tools and workflows Microsoft provides to fix a broken Windows installation without resorting to a full reinstall. The most common and effective approach is the DISM + SFC workflow: run DISM to repair the component store, then System File Checker to restore protected system files. When those tools are insufficient, an in-place repair install through Windows Settings can refresh the operating system while preserving files and settings. Other repair topics include fixing Microsoft Edge, recovering the Copilot sidebar, using CHKDSK for disk errors, and leveraging WinRE Startup Repair for boot failures. The tag also touches on package management tools like UniGetUI that include self-healing features.
