Erik,I have been noting the slowdown on almost every customers machine I built before I started taking a look at some of the security patches and realizing that not everyone of them is needed for every installation of XP.

Hi!Thanks for the heads up on this. I un-installed the 811493 patch and WOW! my system did improve in performance!MSFS2K2 is running much better along with ALL my applications after removing this patch.I was wondering why the performance of my system had decreased, even with my other applications besides MSFS.Once again, thanks for the info, it really helped!Scott :-)ATP/CFII - KCOS

Thanks for the headsup. Tomorrow is "housekeeping day" here and I'll skip that update for sure.Doug

A BIG "thanks", Eric for sharing this info...had overall system slow down past few weeks that resembled some sort of major memory or drive problem, but after uninstalling that security update all is back to normal again here.Eric....you da' man!Dave

Wow! I thought I was going crazy with my computer. Performance was degrading and I've been playing with my fs2002 graphics settings. I just uninstalled this patch and will see if it helps.

Same here..it was acting "tired". Killing Q811493 did the trick! THANKS!

Hi,I don't have very much XP-knowledge, so can you please tell how to erase/uninstall Q811493?Jan"Procul Negotiis"

Jan,Goto control panel,add/remove applications (I think)Should be listed there down the bottom.

Easy. Control Panel> Add/Remove Programs. Scroll down to Q811493. Click remove.Removing it really does make a noticeable diffrenece as posted above.System: [email protected] 8INXP HT Enabled1024 PC266RAMRadeon 9700Pro 128 Omega DriversTurtle Bay Santa CruzSaitek X-45Win XP Pro
