Love to play with Windows 11 and 10. Suggestion - Going for Registry change or system files edit then remember to take a backup or create a restore point before Starting.

  1. Hi, I know it’s been a while since you wrote this, but came across the problem myself and it’s tricky little #$%$. In my instance, the threat message comes up and may or may not allow my mouse or keyboard to connect on post 2. It seems intermittent. It also exhibits, when I can put in my password, a very slow connection to the home screen.

    I noted in your article – #3 – to use a patch for windows 10. I followed the links and the connected articles only mentioned 7 and XP – the patch I tried for 64 bit would not load because of OS incompatibility.

    Do you have any updates to the article for Windows 10? Seems like something is missing.

    Thanks in Advance,


  2. Your solution to the BitDefender error message worked! I tried several others that did not work.
