Hello,
after I installed the latest Updates (30 & 31th Oct) from MS and also the Fall Creators Update (1th Nov) I had to boot my machines in safe mode to disable Anti-Ransomware-Beta in services. Otherwise my machines slow down some seconds after the computer booted into Windows Desktop. It looks like AR Beta 9 has a problem to load and causes the computer to slow down that it looks like a freeze - I opened the taskmanager and it opens 10 minitues after I clicked on it. Have the problem on every computer I tried. Can I do something to report some additional informations that may help you?
