Hi, hope this is posted in the right place. I am upgrading from xp to windows 7 but I'm gathering as much info on windows 7 as possible now because it will be a time before I can install windows 7 and I want to learn about it in the meantime. I downloaded a file from MS website about the help files not being in windows 7 for 32 bit installations. It was an msu file. On checking if it opened ok I got a message saying that windows did not recognize msu files. Is there any programme that can be used with xp to read msu files? Thanks for reading and in advance for any help offered.
