Windows XP-Pro sp3 in question here. To automatically download of MS patches, but not automatially install, is my preference. Having elected to install June's downloaded updates, my PC would only boot to a black screen with underscore, so I suspect either a conflict with my software or a corrupted download. I recovered my PC from a drive image backup, with the downloaded patches already there awaiting installation. Because of suspected corruption, I now wish to enforce a fresh download of the patches before trying them one-by-one. Can anyone suggest how that can be done - either delete the waiting downloads from wherever they are, or select them for download again?? How ??
