Does your registry got corrupted and displaying registry errors? I know its quite irritating when you got such error message in middle or start up. Most guys think that external software’s and formatting system can only solve such problems. If you are one of them, i will prove that you all are wrong and we can repair our system as perfect new one without installing any new software or formatting windows system. We can repair our system in less than 5 minutes and most amazing thing is that i will explain you manual method of doing that. So friends, today i am going to explain you How to repair corrupted system files in windows manually. For repairing system, you just need to know windows inbuilt tools that almost 99% of guys doesn’t know as windows never focused on that feature. 

I have also explained another method in my previous post “How to fix corrupt files in windows”. So today i am explaining a new manual methods to fix windows errors and repairing system files.
Yesterday i was browsing my sytem32 folder in windows and checking some executable. I was very curious what these executable do and in fulfillment of my curiousness i found something really awesome that will make you all of them crazy. I founder something called “webfldrs” and you all will be amazed to see what it serves. Its absolutely serves for different purpose as its name suggests. This windows executable repairs everything in windows system. Its has several features listed below:

1. Repairs all detected reinstall problems.
2. Verify and repair registry entries for user windows programs.
3. Validates the shortcuts.
4. Reinstall if the file is missing, or an older version exists.
5. Reinstall if file has different version.
6. Reinstall the dll or exe if file has different or invalid checksum.
7. Verify local registry entries are present and repair if not.

Guys can you make a guess which of the above features i like most?? I love 5 and 6 feature the most? Why?? Answer is quite tricky but easy to guess. Reinstall if file has different version, or different check sum or invalid check sum. What the hell is this checksum.. Aha….. Checksum is the technique or method to verify the integrity of file. When Microsoft has designed exe or dll or simply a file they have calculated a checksum parameter. Now when some virus infects that file or attach itself to it, what happens is that, its value of checksum changes(as checksum calculation is based on bits, as extra code is added to it so its size surely gonna increase and number of bits involved will also change). So you now come to know why i like 5 and 6 points. If still not, guys they fixes the windows system files that viruses has infected or corrupted.
 That was the background as i want to teach you hacking not just wanna make you script kiddie. So lets learn how to repair corrupted system files in windows manually.
