Using Win Xpsp2 Office 2003
When I run CCleaner My office word 2003 reaches in original default setting

like – default zoom 100
un check update field (in option -> print tab )
un check view hidden text (in option -> View tab )

but I also want to clear recent file list of office word2003

I want to set word in view 125% View hidden text & update field when printing

so that please give me a way to this problem

This has been mentioned before, and unfortunatly you can't have cleaning one without cleaning the other .

But some application do this job very well like Privacy Guardian
than why not CCleaner(the great one)

I do not understand which file(s) responsble for this

All the entries "responsibles" are stored in the winapp.ini file

Open it in notepad, search for [Office2003]
Find this string, that IMO (repeat IMO) is "responsible" of Word settings deletion:

and edit it like follow (just start with a ; for temporarily deactivate)

Save and retry an Analyze process. IMO (repeat IMO ) in this way all the crap
will be detected/deleted, except Word settings. Sorry i can't try this tweak on my
own computer, since i don't have Office2003 installed.

NOTE
As written in winapp.ini file itself, editing it is dangerous.
First save somewhere a backup copy of the original winapp.ini

If you don't want CCleaner messing with your Word 2003 setting you'll have to untick Office 2003 in CCleaner because it not only removes the Recent File List but the settings as well, actually alot of cleaning tools do that, i.e.; Spybot-S&D, etc. That's soley because Word stores it's Recent File List in the Settings. The best way to clean Word's Recent File List is to either do it in Word itself, or completely disable the Recent File List by lowering the number of recent files it will remember.

However, there is something wrong in MS Office detection.
On my PC is installed Office 2000, and CCleaner detects both Office2003 and OfficeXP
Maybe this isn't a CCleaner fault, since in my
registry path HKCU\Software\Microsoft\Office\
are registered 10.0 11.0 9.0 and Word
