Before the installation of CCleaner v2.19, I checked each of my user's CCleaner configurations for accuracy and inclusion of specific cookies and files/folders. Each user on the CCleaner computer has their own registry settings. WinXP SP3 IE8 is installed with the following settings for the Browsing History Delete:
Preserve favorite website data: No
Temporary Internet Files: Yes
Cookies: No
History: Yes
Form Data: Yes
Passwords: Yes
InPrivate Filtering Data: No
If you set Cookies: Yes, IE8 will wipe out your cookies regardless of your CCleaner settings so setting IE8 so it preserves cookies allows CCleaner to selectively remove cookies.
Users on our CCleaner equipped system include an administrator and two power users. Only the administrator has full access and results from CCleaner actions. Those without administrative rights may not have access to remove files. For example, power users can't remove all the Temporary Internet Files so CCleaner's actions in this regard leave files untouched. To overcome this, we allow IE8 to remove the Temporary Internet Files. The lesson here is to know what application has the rights to carry out your wishes. CCleaner and IE8 have different actions and rights and you will need to analyze these to get them assigned correctly.
Before you update your CCleaner, you should run a batch file to capture each user's CCleaner settings. The batch file looks like this:
@echo off
rem This batch file exports (regedit /e) CCleaner current user settings
rem from the registry to a regedit version 5 file, CCleanerSave.reg with username prepended
regedit /e %USERNAME%-CCleanerSave.reg "HKEY_CURRENT_USER\Software\Piriform\CCleaner\"
Look at what this file saves and you get an idea what CCleaner settings are placed in the registry so you can manage those settings better. A text file of commands for restoring the settings is attached to this post.
I use NirSoft's IECookiesView application as an aid in testing where cookies are involved. But this application cannot save and restore cookies which would be a useful utility to have. It will save a text version of the cookies which is informationally interesting but doesn't resurect deleted cookies.
My results: I had some problems with the new version of CCleaner but I had backups of my CCleaner settings and cookies so I simply uninstalled CCleaner and reinstalled it and it seems to work well.
I would be interested in the CCleaner developer being more clear on exactly what changes were made in the new version 2.19 with regard to IE8. I think transparency in letting users know some detail of exactly what was wrong and how it was corrected would provide users with more confidence in the product and our ablilty to use it. Thanks for all the work on this fine product!
