System Restore would replace the file. You might try SFC to repair missing
files. Do as I suggested, after those things are done.

The System File Checker tool

To determine whether the issue that you are experiencing is caused by one or
more system files that are used by Windows Vista, run the System File
Checker tool. The System File Checker tool scans system files and replaces
incorrect versions of the system files by using the correct versions.

To run the System File Checker tool, follow these steps:

1.Click Start, and then type cmd in the Start Search box.

2. Right-click cmd in the Programs list, and then click Run as
administrator.

3.If you are prompted for an administrator password or confirmation, type
your password or click Continue

4.At the command prompt, type the following line, and then press ENTER: sfc
/scannow

When the scan is complete, test to see whether the issue that you are
experiencing is resolved.
