Desktop Icons are messed up??

It didnt work.

It didn't work though.

Just another question, if I decide to like format my pc with a CD...would it matter if I get Windows Professional or Ultimate even though the PC came with Home Premium?

I am not the frequent user of this PC, I only use it sometimes. My parents use it all the time. I just ran a scan like I always do every week and, well, the icons were messed up. I know that if I format, I will lose all my data, my question was...would it matter that I currently have home premium?

Looks to me like SAS has emptied some or all entries from C:\Windows\Installers where many programs get there icons from. Your easiest(?) option is to re-run the setups for the icons that have reverted to the "default unknown". This will repair their entries in the installer folder. It used to be a very common problem with M$ office.

This may not be considered as an answer, but I have a L505, and it is being used for over a year same as it came except a couple of system restores. Its performance is so good that I have never thought upgrading it. I am using Ultimate on my G72, so I cannot tell you not to upgrade, all I can say that it is stable and its performance is so good with Home Premium, and I never risked it to upgrade to Professional even though I had a licence for it before.

About the icons, whenever my icons are my messed up, I go to Properties, change icon, put the address exactly to the address bar (C:\Program Files\Program\Program.exe for example, instead of using the"installer\shell\program icon" -as it was in your screenshot-". Just copy the target without quotes to the icon address bar, and press enter. There should be icon files in the exe file.
