Programs Slow First Time Opened

This just started. When I open a program or Windows Explorer it opens very, very slow the first time. If I close the program or Windows Explorer and re-open it, it will open fast the next time and each time thereafter. But, when I reboot the problem starts all over again. It almost appears that prefetch stops working after a reboot.

I checked all the normal things - defrag, check disk, msconfig, virus scan, temp files, temp internet files. Nothing works. I am loosing my hair. Can anyone help?

Thanks a lot.

would system restore help? have you recently downloaded a security update from microsoft

Thanks Frebo.

Yes, I downloaded a windows update several days ago. In fact, I believe there were three of them. Everything seemed ok right after the updates. I had a whole bunch of restore points built up so I thought it was time to delete all but last one. So system restore is not an option.

did you download security fix 811493 microso soft admits this download causes slowdown in your computer also net frame download causes problems for some users

I looked in add/remove and found 811493. So, yes, I did download that one. I never uninstalled one of these before. Should I uninstall this?

What number is net frame?

Frebo you are THE MAN. Your tip led me to do some quick research on 811493. This is screwing up a lot of computers. I uninstalled it and now my computer is running like greased lightning again.

Thanks again and again.

glad things worked out most people download the updates without even checking what they are (including me) i now research every one of them they dont always work.

check in your windows update and see if net frame is still there if it is you did not download it

I did not download that one because I read about the problems it can cause before hand - something to do with "phantom" users, I believe.

Hi Folks,

I'm glad to have read this thread, as I had the same experience. My system slowed down considerably, but after uninstalling the 811493 patch, I'm smelling burning rubber and nitro fumes again when I fire this bad boy up! :D Thanks!
