Windows 10

Is Avast Premier compatible with Windows 10?If so,has anyone else had the critical error message saying the start menu and cortana are not working?

That is a windows error http://answers.microsoft.com/en-us/windows/forum/windows_10-win_cortana/critical-error-start-menu-and-cortana-arent/d0a892fa-949a-4771-9f93-55a75a71df87?auth=1

I had the same problem. My husband found a fix on Windows Central forum. So far so good, but it is definitely Avast causing the problem. Seems a little weird since it is the start menu and Cortana that fail. Yet, all info points to Avast being the culprit! I hope that Avast comes up with a fix for this, even thought my husband fixed it, it is likely to happen again. BTW, I am running Avast free.

Yes, I have also had this problem both this morning and last week. Last week my father was able to follow the instructions given on the Windows Central forum and eventually the start menu and Cortana began to work again. Today however, after several hours of trying all options suggested our last resort was to switch off Avast. I cannot say I am altogether comfortable with this option after paying for Avast Premier and now leaving my computer without full cover but it has been the only way to remove the ‘start menu and Cortana have stopped working’ issue.
