Well, another common error that we get is this one, “Windows cannot find ‘msconfig’. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.”
First do a complete system scan before you proceed. It might happen that some virus did this thing.
After you’ve scanned your computer, open My computer, Go to your windows folder and hit Ctrl + F. This will open the search pane. There, Click on ‘All files and folders’ and in the ‘All or part of the file name’ field, enter msconfig.exe and hit enter.
Let it search for it. In the meanwhile, open regedit (START>RUN>type Regedit) (Cannot find run command? Click here). Before proceeding, backup first (How to backup your registry).
Now, go back to the search window and look where msconfig.exe is. If you can’t find where the file is, right-click in an empty area of the window>view>details. Note down whatever is written in the ‘In folder’ column.
Again, go to regedit and navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\
Here, look for MSCONFIG.EXE. If there isn’t a key of that name, right click on App Paths>click New…>key. Name this key MSCONFIG.EXE. If there’s already a key named click MSCONFIG.EXE click it. In the right pane, double click the ‘default’ string and in the dialog box that appears, enter the path to msconfig.exe that you noted down in the value data field, including “msconfig.exe” in it. For example, if msconfig.exe is in the “C:\WINDOWS.0\pchealth\helpctr\binaries\” folder, then enter “C:\WINDOWS.0\pchealth\helpctr\binaries\msconfig.exe” in the Value data field.
