me again well I seem to have found the solution it seems my problem was a corrupted or missing Autoexec.nt file heres what I did for anyone with the same problem instructions: 1- Open Explorer --> click on Tools menu --> Folder Options --> Click on the View tab --> then check the options "Display contents of System Folders" and 2Show hidden files and folders" --> Uncheck the options "Hide extensions for known file types" and "Hide protected operating system files" (after this last action you will get a warning message but go ahead anyway) --> click on the button "Apply to all folders" --> Accept and close that window and then click on View menu --> Details. 2- Open the C:Windowsrepair folder and copy the autoexec.nt file by right click and Copy on it. 3- Open the C:Windowssystem32 folder and paste the autoexec.nt file on it (accept replace old file if necessary). well it worked for me anyway.
