How do you enchant weapons in oblivion PC

never played it on the PC but in 360 you go to arcane university and use an altar of enchanting or if you have the wizards lair plugin then the wizard house has an altar

or you can get frost crag spire (DLC) you could find a place to download it for free on Google.....i have the 360 version and PC version i download the PC version and all the DLC's for free....so you could just get that.....it comes with a spell making and echant alter.....and and a lot more.....(other DLC's: Dun Barrow Cove, Battle Horn Castle, Merunes Razor, Horse Armor, Repairing the Orry, Deep Scorn Hollow) That's all think....
