“C:\Windows\_DEFAU~1.PIF Invalid program file name, please check your pif file. Choose close to terminate the application”
Can anyone help with this please. I have taken a lot of peoples suggestions in running different registry cleaners, performing an sfc scannow operation but I cannot get rid of this startup message. Any suggestions??
Go to Start, Run and type in regedit and press Enter. The will start the Registry Editor. In the registry, go to HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows\CurrentVersion\Run. Here you should see a list of programs that start with Windows. Have a look to see if there's anything to do with the PIF file that's trying to start up (or any other thing that might be related to it) and delete them. If there isn't anything, go to Edit, Find and search for _DEFAU~1.PIF. If this brings up the entry, delete it.
Another thing you could try is to go to Start, Run and type in msconfig and look in the Startup tab to see if there's anything in there to do with it and if there is, disable it.
If nothing is there, then go to My Computer, then C:\ then Windows. Find the _DEFAU~1.PIF file and open it with Notepad. See what file it points to (PIF files are MS DOS shortcuts anyway) and go through the previous steps to remove it from startup.
One thing I should have mentioned - the file might not be called _DEFAU~1.PIF - ~1 appears on the end when it's been shortened to 8 characters, so do all the searching for _DEFAU. This will make sure it finds the file that starts with the right name.
When I run the regedit option you mention I do find what is called a (Default) entry and under the Data option it says (value not set) whereas all of the other files have specific file extensions. Should I delete this? Could it be the defau~1.pif problem I an having at startup?
You should leave that one, it's supposed to be there. Try the second method of going to My Computer, then C:\ then Windows. Find the _DEFAU~1.PIF file and open it with Notepad and see what it says. Remember it might be called default and then some numbers, as files with ~1 on the end have been shortened for DOS.
