Why Do Windows Updates Keep Failing?
Microsoft Store and Windows updates are notorious for encountering problems, especially following previous updates. No one fully understands why this happens—not even Microsoft—but it’s likely due to minor corruption in update files or unanticipated compatibility conflicts between updates. Because of this, rolling back one update and then trying to install the latest version usually resolves the issue.
