Same here. The Last Used On column itself isn't enabled by default. Perhaps Microsoft dropped the feature for performance.<quoting Raymond Chen [MS]>In order to get the "Last Used" and "Frequency" values, Add/Remove Programs needs to know the name of the EXE so it can ask the Start menu "Hey, how often did the user run this program, and when was the last time it happened?" Notice that there are no clues in the registration above as to the identity of this EXE file. So Add/Remove Programs starts guessing. It goes through all the programs on your Start menu and compares their names with the display name of the uninstallable item. It looks for Start menu items which share at least two words with the words in the DisplayName. For example, if there were a Start menu item called "Pretty Decent Windows Program", this would count as a two-word match ("Windows" and "Program"). It then takes the one with the most matches and decides, "Okay, I guess this is it." Suppose for the sake of illustration that the best match is indeed "Pretty Decent Windows Program.lnk", which is a shortcut to "C:\Program Files\LitWare\Decent Program\Decent.exe". Add/Remove Programs would decide that "Awesome Program for Windows" should get the icon for "Pretty Decent Windows Program.lnk", that the frequency of use and most-recently-used information for "C:\Program Files\LitWare\Decent Program\Decent.exe" will be displayed for "Awesome Program for Windows". </quote>It's nice that MS has dropped this feature in Windows 7.Ramesh Srinivasan, Microsoft MVP [Windows Desktop Experience]

... so it's there as an available column but it doesn't work. Doesn't sound like they necessarily 'removed' it. It just doesn't work anymore. The choice Microsoft should take is remove the column from the build or fix it's functionality

Thank you for reporting it. I will forward this thread to our feedback team. :)

Cool. It is a rather inaccurate function in older builds. It'd be just as well to have it removed if it isn't something that is easily fixed to work right
