zycreeper Posted November 9, 2014 Share Posted November 9, 2014 My mom's Thinkpad E431 installed Windows 8.1 when she bought it. But she needs Windows 7 to do some works.I cannot install Windows 7 on the notebook because I can't activate it.Is there any way I can activate the windows?

mdbill Posted May 26, 2015 Share Posted May 26, 2015 Run SLUI 3 from a CMD window.If it fails, call Microsoft. They'll activate over the phone. Quote Link to comment Share on other sites More sharing options...
