I went to the download page of Microsoft to download sp1 for vista and it tells me to install it from windows updater on my laptop, but when I go onto that, it just displays an open window saying "The page failed to load". Should I just download it of the website and install it or will that stuff up my computer?
Better to fix first the problem of "The page failed to load".
Standalone download for Vista 64bit: Windows Vista SP1 64Bit
Standalone download for Vista 32bit: Windows Vista SP1 32Bit
Edit: Forgot to add that standalone downloads are fine. I'd also recommended slipstreaming the update to create a new ISO of an install disc which already includes SP1.
