How to Run Shell.Dll

If You Can Log in to Windows...
1. Power on the computer and log in to Windows with an administrator account.
2. Click the 'Start' button, 'All Programs,' 'Accessories' and then 'Command Prompt.' The Windows Command Prompt dialog box appears. Note that you can type 'Cmd' or 'Command' in the 'Start' menu search box and press 'Enter' to access the command prompt as well.
3. Type 'sfc /scannow' without quotes at the command prompt. Wait for Windows to scan system files and verify them. If Windows detects a corrupt or missing 'Shell32.exe' file, it replaces it from the Windows Protected Files hidden folder. If the file in the cache folder is corrupt or damaged, Windows prompts you for the installation disc so that it can copy the file from it.

4. Shut down the computer and restart it. Insert the Windows installation disc into the optical drive as soon as the system restarts. Press the 'F1,' 'F12' or whichever other key your system requires to access the boot menu for your computers. Select the 'Boot from CD' option and press 'Enter.' Note that some PCs boot from the CD automatically without user intervention. If you need to press a key to access the boot menu, the system usually displays the key you need to press on the screen during the boot process. If the machine does not display the message, refer to the user guide for your computer.
5. Click 'Next' when presented with the 'Select Language' screen. Click 'Next' on the 'Repair Your Computer' and 'System Recovery Options' screens. Note the drive letter of the Windows Recovery Tools in the second 'System Recovery Options' window. Note that it is probably not the 'C:\' drive, as Windows usually writes the files to a partition separate from the one used for the operating system.
6. Click 'Command Prompt' in the 'Choose a Recovery Tool' window. The Command Prompt appears on the screen. After the command prompt appears, type the command:'sfc /scannow /offbootdir=f:\ /offwindir=f:\windows' -- include the spaces but not the quotes. Change the 'f' variable that appears twice in the command line to the drive letter that appeared in the 'System Recovery Options' window. For instance, if the drive shown was the '(L:)' drive, change the 'f' to 'l' in the command line.
7. Press the 'Enter' key and wait for Windows to scan your system and check for missing or corrupted systems files, such as System32.dll. If Windows finds problems, it replaces the files with ones from the installation disc.
8. Type 'Exit' to close the Command Prompt window and restart the computer.
