This is the strangest problem I have imported folder.reg and directory.reg but I still can not start explorer.exe.  If I type explorer.exe /e it will launch ok.. If I launch it from a shortcut it launches fine.  But I can not get it to launch by clicking on explorer.exe.   All other executables work fine but for one other which I try to run which is Windows7UpgradeAdvisorSetup.exe it gives me error "The system administrator has set policies to prevent this installation."   

 

I have checked local security policies and there is none in effect.  I have ran software to check for policies but I can not find any policies to cause the above two problems.

 

Ran Drweb nothing found

Adwcleaner nothing found

Malwarebytes nothing found

 

So I thought ok let's try an upgrade install to repair my Windows 7 OS but I get message that Windows Vista SP1 has to be installed at mininum so I am not able to do a repair install either.  Except for the two problems everything is working fine and giving me absolutely no issues at all.

Maybe some kind of virus corrupted your windows file association in registry. Download this reg file http://www.mediafire.com/download/x6b6zxici9rs5x2/folder_fix_w7.zip and unzip it and than run the reg file that was inside. But i strongly suggest that you backup you registry first just in case.

I tried that and I have done both the folder and directory registry fix but to no avail.  I did a full registry search to make sure there was nothing calling explorer.exe to run but nothing.  I than went to all my policies and all are unconfigured.  Strangest situation ever so I tried to do a bare bones metal restore back to 8/1/14 of my C drive and the same issue.. So my last full image backup not file folder backups the issue existed. I only discovered it because I was at the command prompt and wanted to lauch explorer so I typed the file in the command prompt to launch it and discovered the error.  Never seen an issue like this one before.. It's got me totally stumped.

Try using tool called rkill which can be downloaded here http://www.bleepingcomputer.com/download/rkill/ it can show you if you have running malware processes and stop them and will reset file associations which i hope in your case can help you fix the problem, but if not i shall sugest something else than.
