thinpad X1安装office2016提示激活

thinkpad X1很高大上，也带了OEM版本的office,可是居然不带outlook。

协作重新安装office2016专业版，提示激活成功。可是每次打开的时候总是要提示激活，如果要换序列号.......一大堆。

最后的原因竟是卸载不干净导致的，要删除两处注册表。

5. Right click the OEM value and click File>Export.
6. Save the key
7. Once the key is backed-up, click on Edit>Delete
8. Repeat steps 4-7 with following key
