I have the student Home Premium upgrade, but am still running the ultimate RTM with a loader. For my MB the slic 2.1 has been reported as troublesome. I tried 8 different loaders before I found one that worked and don't remember which one it was. I basically dont use any of the ultimate features and home would probably be fine, should I go ahead and go with the official home 7 or do you think I should wait and see if there is a problem with the loader after an update? The reason its a delima is it takes me a good 2 weeks to get everything set back up after installing a new OP SYS just cause I have a lot of specialized software.
