Guys, 1. I bought OPL license for Office 2010. Like normal sometimes we need to reformat our PC due to virus issue etc. How to unactivate the license before reformat? Is there such option? 2. Is there an option to unactivate license for WIndows 7 which already installed in a computer so that we could reinstall it back later ? TQVM

There is no need to "un-activate" it will easily reactivate on the same hardware. If it is an Open/Volume license you can actually uninstall on one machine and reinstall on an other without a problem.Rob Williams
