Tweaking.com - Windows Repair is an all-in-one repair tool to help fix a large majority of known Windows problems, including registry errors and file permissions. The installer is available for download here.
Some situations this could work for you might be an error message you receive where something no longer works like it used to. Widespread use for Windows Repair is after a malware infection. While there are many tools to help remove the infection, you will often have issues left over like a disabled Action Center, firewall, anti-virus, or even worse, internet connection. Weâ€™ve seen these hundreds of times. Booting into safe mode and running this program can solve these problems, and everything was working again. Occasionally you might have to change back some settings you have modified, but itâ€™s worth it.
The program adds new features, has no third-party software, no nags, no usage, or time limits. This truly is a breath of fresh air.
