( Windows XP Service Pack 2 )
Skip the manual method and go directly to section "AddonColumns"
When you open the Manage Add-ons dialog in Internet Explorer (in Windows XP Service Pack 2 ), these are the columns displayed by default:
To view the additional columns, right-click the column header and enable the required columns. However, this is a temporary solution, as this column view setting is reset when you close the Manage Add-ons dialog.
To permanently enable all or some of the additional columns, make use of the ManageAddonColumns registry value as explained in the following Microsoft Knowledgebase article:
You cannot use the Microsoft Internet Explorer user interface to change the Internet Explorer Manage Add-ons settings.
Before this KB was released and there was no official documentation at first, I was playing with the ManageAddonColumns registry value, and could guess what this value is for. But, obviously I did not know what are the possible values for ManageAddonColumns.
Each Managed Add-ons column is associated with a number. The following table describes the hexadecimal number that corresponds to each column. To turn on additional columns, add up the hexadecimal numbers of the columns that you want, and then make that sum the DWORD value of ManageAddonColumns. For example, to turn on all the columns, add all the hexadecimal values together, as follows: (0x10 + 0x20 + 0x40 + 0x80 + 0x200 + 0x400) = 0x6F0 To add only the Class ID column, change the value of ManageAddonColumns to 0x80.
Or, add the corresponding Decimal values of the Columns that you want, and assign the value to ManageAddonColumns (Be sure to click the Decimal radio-button in Regedit, in this case)
For Example, to turn on Last Accessed and Class ID columns, set ManageAddonColumns value to 144 (Decimal)
