The I386 folder will still be found on the recovery disk as well as on even an upgrade disk since that is the main folder for system files compressed into cab files found there. This has been in Windows since 98.
That's an interesting thought since Vista now sees several changes made there. The next time I boot ibto Vista I will have to follow the same instructions I just posted above.
Using System File Checker In Vista.
System File Checker checks that all Windows files are where they should be and that they're uncorrupted. If you've done all your virus and spyware checking, error checking and defragging, and Windows is still doing strange things, then SFC can avoid a reinstall.
1. Open a Command Window in Administrator mode:
- Click Start
- Click All Programs, then Accessories
- Right click on the Command Prompt option,
- On the drop down menu which appears, click on the Run as Administrator option.
- If you haven’t disabled User Account Control you will be asked for authorization. Click the Continue button if you are the administrator or insert the administrator password.
2. Start the System File Checker
- In the Command Prompt window, type: sfc /scannow,
-Press Enter.
- You’ll see “the system scan will begin”.
The scan may take some time and windows will repair/replace any corrupt or missing files. You will be asked to insert your Vista DVD if it’s needed.
Close the Command Prompt Window when the job is finished.
You need a Windows DVD to enable SFC to make repairs.
Let me know if you need anything else.
