What is TransitionServer.exe?

The genuine TransitionServer.exe file is a software component of Lenovo Transition by Lenovo Group.
"TransitionServer.exe" is one of twenty or more files in Lenovo Transition, an application pre-installed in "C:\Program Files\Lenovo\Lenovo Transition" in older Lenovo Yoga PC models. It does not start up automatically. Its function in the Transition app is unclear. The Transition app is no longer supported and is incompatible with upgrading to Windows 10. (Consult Lenovo Support before doing so.) It uninstalls when "Lenovo Transition" is selected under "Programs and Features" in the Control Panel. Installing the replacement Lenovo Yoga Mode application automatically removes Transition. "Yoga" family devices open from closed position (zero degrees) to "Tablet" mode, (360 degrees, with display and keyboard back-to-back). The Transition app disabled the keyboard and touch pad after 190 degrees, ("Stand" mode), and enabled a soft keyboard in "Tent" and "Tablet" mode. Lenovo, founded in Beijing, China, in 1984, acquired IBM's Personal Computer division in 2004 and is now #231 of the Fortune 500.
