Upon recently noticing Windows 7 SP1 in Windows Update, I downloaded and installed it without difficulty into our two Dell Studio XPS desktops. If it matters, they are virtual clones of each other, each running 64-bit Windows 7 Home Premium (upgraded from 64-bit Vista Home Premium), and as of this moment both appear to be working quite uneventfully with SP1. I then followed the same steps trying to install SP1 to a Dell Inspiron laptop running 32-bit Windows 7 Home Premium, and that's when my problems started. :-(
The laptop appears to have downloaded it (KB976932), and even indicated it was installing it when I got an indication that it failed. The dialog stated "Error: 0x800f0805," and suggested that I try it again, but to first shut off my security software. I disabled McAfee Total Protection, both the AV as well as firewall (note: both remained fully activated during the successful installation on the 2 desktop machines), then tried to install SP1 again but once again it failed. After mumbling some words in frustration I prefer not repeating here, I then reverted System Restore back to the point immediately prior to my initial downloading and that is where I will remain with the laptop at least for the immediate future. Obviously, I will need to install SP1 at some point, but not until I can find out more about it.
After a day of reading a lot of online reports on the subject, much of which I do not understand (I'm an old (68) geezer, and self-taught user who in no way professes to be anything but a non-professional and borderline intermediate user), I am now more confused at what I am dealing with than before. Much of what I am reading I cannot understand, with a fair amount of the "experts" actually conflicting with each other, and I ended up with Clint's post right here suggesting that we wait a few months, although I am not very clear on the reason for waiting. Clint has bailed me out here before, so considering the puzzling and contradictory things I've read about this, I am going to do just that and see if I can figure out where to go from here.
If Clint or anyone else reading this has any suggestions on how to successfully download and install SP1, I welcome hearing from you. I am going back and reread it, but I read one piece that suggested either downloading and saving SP1 to HD (yes, I know it is HUGE) or else getting it on DVD (from where?), and then installing it that way with everything else disabled at the time. One piece I read actually suggested total removal of AV software, so I clearly have some homework to do before I try to install it again. In the meantime, I am going into "observation mode" for awhile and am open to any advice from the resident experts here.
