the requested lookup key was not found in any activation context

i was trying to figure out why my usb flash drive was not detected when plugged in. so i followed instructions in this link http://support.microsoft.com/kb/925196 to change the registry. bad bad idea. after deleting the UpperFilters registry value and restarting, a lot of things stopped working, for example, couldn't access the H drive. so i repaired the windows os using the reinstallation disk.

after this, things mostly went back to normal, but ie stopped working. basically couldn't navigate to the website by typing the address in the address bar. it gave the error in the title. could still click through links in the home page displayed. i searched the error online, and most pointed to the problem with ie 7, i checked the version i had and it was ie 6. tried a lot of things, installing ie, uninstalling it, repairing os. in the end, what works is upgrade ie 6 to ie 7 by doing all the necessary updates. after this, ie still doesn't work. even worse, it would launch. but then the upgrade came with a unstallation program in %windir%\ie7\spuninst\spuninst.exe to uninstall ie 7. after that, everything works.

usinstall ie 7: http://support.microsoft.com/kb/927177
