Got a laptop here, Dell Inspiron 1501 with Vista Home Basic (32-bit), no service packs. Windows updates give this error. http://support.microsoft.com/kb/958044 The article the error links me to is this one. http://support.microsoft.com/kb/947366 Various support/fixes suggest by MS for this situation include... Using the standalone SP1 installer instead of the web one. It gives the same error. Running the readiness tool. It takes half an hour and doesn't fix anything. Close stuff. Everything's closed, even tried it on a new account. Uninstall security programs. Removed McAfee and disabled windows defender, nothing. A repair install. This had my hopes up as I could use my Vista SP1-integrated disc to repair install with SP1 already installed... but it won't let me, I need to repair install with a non-SP1 disc. I don't HAVE a non-SP1 disc (nor any blank DVDs), and I'm not going to wipe all this lady's stuff. If there any way I could network boot a non-SP1 disc image? This is serious, any trolling will be reported with the speed of a chipmunk on crack and the fury of a thousand suns.
