Does the prompt from True Key to login come up after you are logged in to Windows or even before you login? If it is after you login, you can uninstall True Key from Control Panel. Detailed instructions can be found in Step 2 in the article https://service.mcafee.com/webcenter/portal/cp/home/articleview?locale=en-US&art icleId=TS102329
If True Key prompt to login comes up even before you are logged in to Windows or if you are unable to remove True Key by following the above article, please follow me and send me a PM. I will reach you to help you further.
Thank you that worked.
