How do I repair a Windows image to solve Rocket League issues?
A corrupt or damaged Windows image can cause programs (including Rocket League) to fail or work improperly. Microsoft has an automated tool called DISM (Deployment Image Servicing and Management) that can help fix a Windows image.
Please visit the official Microsoft webpage Repair a Windows Image (Wordt geopend op een nieuw tabblad) which explains exactly how to use DISM.
