Windows Search dialog box is blank!

This is one quirky problem where the Search window is blank and only the "little dog" is visible! It can be seen in the screenshot below (sorry for the low image quality).

This can happen due to various reasons. Some of the fixes that can be tried are:-
1 Microsoft KB – Several dialog boxes are blank: This Knowledge Base article gives some information about this problem and also the resolution. This is worth a try.

2 Installing Windows Script files: JScript, VBScript and other Script Runtime files are used by this Search window (and other windows), hence a missing/corrupted Script file could cause the problem. The Script files can be downloaded here.

3 Reinstall Search Assistant: Go to Start > Run and type %windir%\inf and press Enter key. This should open the Inf folder. Here look for a file named srchasst.inf. Right-click on this file and click Install, you may require Windows installation CD.
