As OEM partner we have received the RTM version of SP1. On my work PC I had to slipstream SP1 RC1 in order to install the Ultimate Version (long story - got bluescreen if I try to install it without SP1).
I know that Microsoft said you require to remove SP1RC1 prior the installation of SP1RTM, but I hoped it still installs :

So, to avoid installing my PC AGAIN - has someone an idea how to get it still installed ? Obviously you cannot remove a slipstreamed SP
