This month (March 2023), I have noticed problems with Windows Updates, not the updates themselves but the process of preparing and carrying out the installation. I have a notion that SecureBrowser might be a significant factor and am wondering if other users of SecureBrowser have also had problems. My suspicion is that Secure Browser has interfered with the Windows update process. I also have a vague suspicion that Secure Browser might have been causing SFC (System File Check) to find problems which it then fixed.
What evidence I have seen is circumstantial but I have not observed problems with systems which have not had Secure Browser installed on them. It would be good to have a tool to ensure that Secure Browser is thoroughly cleaned out.
