De-fragged, installed FSX, de-fragged, installed SP1. Siince I was unable to cure the constant blurring of landclass textures I wanted to uninstall SP1. However, there is no entry in the Add/Remove window. Nor is there any other indication anywhere that I can see of an entity called SP1. Any idea on how to uninstall SP1 without going through yet another reinstall of FSX?It is verified that SP1 is installed by:http://forums.avsim.net/user_files/173338.jpgRegards,Dick BoleyA PC, an LCD, speakers, CH yoke

Go to add remove programs, look for a box entitled "Show Updates" near the top of the window and make sure it is checked. It will then show SP1 for FSX listed there.

Thanks - worked!!!Regards,Dick BoleyA PC, an LCD, speakers, CH yoke
