Cannot edit, delete, rename files in any way (Thread version II)

I'll try that right now, and I wanted to say thatnk you for your help in this matter, it is appreciated...

Nope same thing in safe mode. I can only rename/edit and save files that I have just recently created using 7zip. It would probably work with other apps too, I think its got to do with when they were created, and not so much by what..

I got my MCSE back in 97, and my CNA in 96, So I'm not a total stranger, but I have not came across anything like this before. System was completly scanned for viruses using the latest AVG, then was also scanned using MalwareBytes Anti Malware. I am completely and utterly stumped! It makes no sense?

I'll try it right now

No dice! It did not work, but it did report that not all keys could be written to because the system had them open...
This is crazy isn't it! Hell I came from the days when you had to use ASM to format an old MFM HDD and this is the first time I have completely lost faith in an OS. haha Yeah I'm getting a little frustrated...

I have no idea what to try next, but I think I know where this is going to end. It will be a reinstall of Windows 7 and even then that may not do it. As a roll back position, what is known about rolling back from Windows 7 to XP Pro? I am starting to think I may not have a choice and I don't think I want to install Windows 7 again after this because there is just no information anywhere on this error.

And yes I tried it in safe mode too..haha

I know, I am completely stumped by this as well. I have a software release to get out, so the quickest thing for me to try is a repair. If that does not work then I'll be spending the next 6 hours making sure I have everything backed up and then rollback to to XP Pro I guess. Damn I was just starting to like Windows 7 too! I see where they are going with it, but honestly, its not very often that I get stumped like this where everything you try makes no difference at all. So, I will end up keeping windows 7 but it will be on a virtual box under XP Pro. This is a development system and I just cannot run the risk of my OS suddenly loosing its mind and blocking me from my source code. Right?

Like always, I'm sure that Win7 will be less buggy in the future, but right now its too dangerous for me to use as development OS. I really do appreciate your help and suggestions, and I thank you for your time, but I don't think we're getting this resolved. I'll report back after I do the repair, Is there anything I need to know about that?
