I have accessed windows XP Pro 32Bit on my secondary computer many times with no problems:1. Click Start2. Select All Programs3. Select Windows Update4. Up comes the Windows Update page with all the options and no problems.For my primary computer, I have upgraded to Windows XP Pro 64bit, but I cannot access the update provisions.When installing the 64 bit OS, I am pretty sure that I installed all the updates at that time and did not see my current problem. I also selected auto updates at that time. This is somewhat confirmed (I think), by the fact that I can go into add/remove programs in the control panel and Iam getting security updates listed, latest on September 9, 2009. The last previous time I looked a late August update was the latest one listed, so I am getting updates.When I try to manually check for updates like I did on the 32 bit system, I always get the following page displayed."Administrators OnlyTo install items from Windows Update, you must be logged on as an administrator or a member of the Administrators group. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.Note If you are running a Windows 2000 (except DataCenter), Windows XP, or Windows Server 2003 operating system, you can run the local administrator account on your computer without having to log off and then log on again.To run as the local administrator in Windows XP or Windows Server 2003:1. Click Start, and then click All Programs (or right-click Windows Update if it is available).2. Right-click Windows Update.3. Click Run as on the menu that appears.4. Do one of the following: Enter the password for the administrator. Enter the user name, domain name, and password of a differrent user account that has administrative permissions on this computer."Every time I go through the steps as instructed above, I get the same instruction page again as quoted above, and the same cycle is repeated over and over again but I never get to the update page with all the options (i.e. express, custom. history etc.)When I installed Win XP Pro 64 Bit, when asked for a password, I entered one. Unlike the 32 bit OS, startup of Windows 64 bit required this password every time I started up my computer. I discovered that if I went into my account from the control panel after startup, I could simply delete that password and the computer would start up with no problem, and no requirement for the password. When trying to manually check for updates as mentioned above, I went back into my account and replaced the same password.I am the only user, and the administrator. The administrator account is the only one that is displayed.Is there another place for a password that is applicable to my account? Has anyone else been down this road, and knows what I need to do in order to check updates?No biggie as I am getting the updates automatically, but it puzzles me that I can't access them manually.Thanks:RTH

Google "permissions fix" or something like that. There is something you can do to fix/reset all the permissions I think. I have been down that once but cant remember. Also, I think you should look at the processes. I think I had to go in and turn on some processes that had been shut down. God knows why.Lastly, and this is a long shot, it is possible that you encountered a spyware download around the same time as you upgraded. For sure, get the free spyware checkers and cleaners out there and run them. Good luck.UPDATE: a simple google reveals below. Google is your friend. Use it....http://support.microsoft.com/kb/316524

Download Dial-a-fix. Install and run. Hit the checkmark at the bottom of the page, deselect "check time" at the top, then click go at the bottom and let it run. If any error messages pop up just click ok until they're done. If that doesn't fix it, you'll need to access the additional tools by clicking on the hammer icon at the bottom, then select sfc purge and hit go, then sfc scan and hit go. At this point you'll need your Windows XP Pro x64 CD. If that still doesn't fix it run the "fix permissions" utility on the same tools page. If none of the above fixes it you've got something much more serious going on, perhaps a failing hard drive or a virus infection.

You can run the 32bit version of IExplorer which is in the same directory as the 64bit default Iexplorer ... just create a desktop icon to it.Also the 64 bit version hardly ever gets an update.
