p7805u windows 7 mistake :(

my brother new to computers was playing on my p7805u while i was away and my cousin who knows a little bit but not to much about computers was watching soooo this is what happened my little cousin went into task manager to delete a process that had frozen *my firefox* for some weird reason and while he was doing that he noticed conhost.exe he though it was a virus so he went into the location of the file and deleted it so now im stuck without a cmd and dont know how to fix it other than doing an upgrade to windows 7 again and keeping my files but losing my programs which i dont want to do because i have soooo many and it will take me forever to put back all in its place is there any 3rd party program that can fix this issue

thank you to anybody that can help me with this

 

you can't do a system restore? if not do an F8 at boot and try a recover, you may need your system disk........

 

yes, get a system disk of some sort for the version of windows you use. Boot from this disk but see if there is a repair option available on the disk. I have vista so it might be a tad different for 7 but in vista it is capable of detecting that one or two rather important files are missing or damaged and it can repair them without a complete reformat.

 

You could try sfc.exe. Here is an explanation.

 

nah sfx.exe dont work because i dont have a command promt to open up lol conhost.exe is command promt.....and for some reason having trouble burning a windows 7 dvd so im stuck atm

 

copy the file from another computer and place it back...

 

tried that dint work does it have to be from a 64bit one like mine? or can it be from a 32bit windows 7? i tried from a 32bit windows 7

 

has to be 64.

 

If you have a 4 gig usb drive, download 7 from digital river and usb tool from MS. Boot from usb then choose the repair option. I use if for clean installs but have never used the repair funtion.
