Changed MS Outlook Settings with 2.28 and 2.29 in CCleaner Bug Reporting Posted June 3, 2010 I think I have found the solution for this problem. There's a small but important difference between CC v2.27 and higher versions. The following lines are the original ones from v2.27. [Office 2003] .......... Regkey3=HKCU\Software\Microsoft\Office\11.0\PowerPoint\Recent File List Regkey4=HKCU\Software\Microsoft\Office\11.0\Publisher\Recent File List Regkey5=HKCU\Software\Microsoft\Office\11.0\InfoPath\Recent File List ............ In versions v2.28 and higher the bold letters k were changed to K and that could be the reason why CC started wiping in those versions as described by MRG7 in this thread. So, anyone who doesn't want these settings to be wiped should write his/her own Winapp2.ini entry without one or more of these three lines. (See also post#8 by Nergal).
