The International Space Station will deorbit in glory

Twenty one years ago, there was announcement that service pack 7 for windows NT 4.0 had been installed on computers on the ISS.

NT users on earth had to install service pack 6a then manually install a load of hotfixes to be up to date. NT 4.0 did not have the automatic updates that we are used to.

Microsoft never released SP7. It is my opinion that they chose not to because they wanted everyone to buy windows 2000. I'm still pissy about it.
