This is my home PC and I'm the only one that uses it (the numerous keys with worn-off letters ensures that...ha!). I've only just installed it on this PC after my other died a week ago. I thought maybe it was somehow preset for that, but I've checked auto correct and it's not there. I actually can find nothing with an apostrophe in auto correct, as I've only been using this for a week and haven't added all my entries yet. I just don't understand it, and it's highly irritating.
