I always keep my computer fully up to date. (that includes Windows and CIS)
I have a Windows 10 PC 64 bit machine
For each of the last 2 months when my PC has installed the monthly Cumulative Update, on reboot, I have had a black screen with Cursor and just the CIS widget showing. Nothing else.
At that point, I have been unable to do anything else but rest my computer. Startup Repair does not work and I cannot find any Restore Points in Safe Mode even though I have created them.
All I can do is to Reset my PC.
Last month after your warning, I re-downloaded a new, updated version of CIS with the issue fixed, and everything was fine, but this month, you obviously havent noticed yet that the same problem just recurred. Even when I updated Windows first, the problem recurred as soon as I re-installed CIS.
So I have reset my PC another twice, and have only been able to install Cloud Antivirus to avoid the issue again.
I am afraid that I cannot give you any more info because of the situation.
