0patch support
Hi everyone on this thread! I am Mitja Kolsek, co-founder of 0patch.
User nord899 was kind enough to notify us of this thread and some functional issues that are being discussed here and suspected to be caused by 0patch. I think it's best to troubleshoot these issues via our support channel and then bring resolutions back here for everyone to read. So I'm inviting all users suspecting 0patch is causing any problem to contact us:
[email protected], or
Help Center.
Meanwhile, some feedback possibly related to issues being discussed:
1) 0patch Agent has, in the past, been guilty of occasionally stealing focus from other apps when displaying popups. We fixed this to our best abilities and stopped getting reports but in the complexity behind Windows there may still be remnants of this issue somewhere. In general, if you set popups to the quietest level ("Inform me only about important system events"), that should minimize this issue if you have it. Also, the stolen focus was always associated with our popup being shown at that exact moment.
2) 0patch causing some apps to not run: While we made sure to minimize any interference with running processes, it can still happen that our agent DLL's mere presence in the process, and the single hook that we set, cause a problem in the process. For instance, this happened with Mozilla Firefox 72 and prompted us to issue this article:
Mozilla Firefox 72 can crash upon launching when 0patch Agent is installed – Help Center. This may happen with other apps as well and we'd like to investigate every instance users may stumble upon. As a first course of action, affected users can exclude the affected app from being injected with our DLL as described in the above article about Firefox.
3) Problems with printing: Some Windows users have reported that Microsoft's workaround for CVE-2020-0674 broke printing for them. Our micropatch for the same issue (
0patch Blog: Micropatching a Workaround for CVE-2020-0674) avoided many of Microsoft recommendation's negative side effects including this one, as far as we could test it. But if you suspect 0patch is causing problems with printing, try disabling it (you don't have to uninstall) or just exclude the affected app from patching in 0patch Console -> Applications -> Patched Applications and see if the problem goes away.
Looking forward to solving these issues,
Mitja
