Verify all the protected system files in Windows are intact

A new feature called Windows File Protect (WFP) appeared in Windows 2000. This allowed you to protect your system files against accidents or other programs replacing them during program installations. This allows you to increase your operating systems stability.
Here are the system files protected by Windows:

*.SYS (System Files)
*.DLL (Dynamic- Link Library)
*.OCX (Active X Control)
*.EXE (Applications)

As strange as this may sound, there are 3 True Type fonts that are also protected. Windows calls on these fonts for use in certain programs, and they are:
Micross.ttf
Tahoma.ttf
Tahomabd.ttf

This protection is activated by default when Windows is installed, but if you suspect that WFP is not functioning correctly then it is possible to perform a manual scan and restoration if necessary. The missing or damaged files will be detected and replaced with the original files.

Click “Start”, “Run” and type “SCF /SCANNOW”. Click on “OK”.

The verification of the Windows protected files will start…

If Windows detects that files have been changed, it will ask you to insert your CD so that it can find the source files.

And that’s it. A manual verification is not a bad thing, especially when these things become more and more automated it allows you to keep a track on your system. A precaution that is not over the top when talking about your system files…
