Ever since I upgraded from Win10 to Win11 Pro on one of my computers, I have been having problems with Windows Updates. I think the problem is Acronis True Image Backup. I know that one of the modules, Try & Decide, conflicts with Win11’s Core Isolation. If you turn off Core isolation, you can not re-enable it without disabling tib.sys. Here is a quote from one of the members of the Acronis Forums.
ACRONIS – TIB.SYS & Core Isolation
rename the C:\Windows\System32\drivers\tib.sys file then do a Windows restart, i.e. I renamed the file to tib.~sys
Anyway, today I was updating Win11 to KB5040527 and as usual, it failed. After rebooting, and trying again, I got it to update. This has been the normal procedure for one of my machines, while another computer I have on Win11 updates normally.
So, I thought about trying again with Acronis removed entirely. I restored a previous backup, and I uninstalled Acronis, and then I re-ran the update, and voila, it updated fine. I then reinstalled Acronis.
I mention this only in the event others are having Windows Update problems and have Acronis True Image installed.
I’ve come to the conclusion that as long as you don’t mess around with the Win11 Core Isolation, (like turning the switch off which allows the Acronis Try & Decide tib.sys driver load), there “should” be no conflicts. I can’t guarantee this is the fix, but it’s worth investigating if like me, you are having Windows Update issues.
Also, I had previously tried a few over the top installations and they have all failed. Anytime I have tried to update a machine with Acronis installed, it has failed. I have not been able to update from Win10 to Win11 on two machines. I had to clean install on both of them. So, that is my next test. My plan is to uninstall Acronis the next time I try an Over The Top fix or if I decide to upgrade one of my other machines from Win10 to Win11.
