I forgot to mention earlier that I temporary disabled system restore due to security concerns plus I disabled Simple folder shares due to security concerns. But, in HKEY_USER, I left S-1-5-21 and S-1-5-21 Classes intact. I was thinking, is it possible to get the stuff back by going back to either .DEFAULT or S-1-5-18 and exchange Guest with Admin. But then, what else can I add in and which folders do I need to attach to them and how to do it properly and correctly without messing up the registries? I also previously installed System recovery to the C:\ drive using combofix I caution that using combofix is OK, but whatever registries I edited with be put back in default automatically. I would have to manually search these registries again and re-edit them to my liking. I also caution that using Malwarebytes is also OK, but it will always give me a warning that using Registry Editor is a virus, but its not! I always have to set it to IGNORE. If I set it to DELETE, I can still use Registry Editor and the registries will be left intact even if I modified them to my liking beforehand. Since I have system recovery at my disposal, is there a way to just ONLY recover/restore .DEFAULT , S-1-5-18, S-1-5-19, S-1-5-19 Classes, S-1-20 & S-1-20 Classes and recover the necessary folders including Microsoft and ZoneAlarm and leaving everything else intact without wiping and reload the C:\ drive and without reloading all the applications, licenses etc.? I went to HKEY_USER and changed both .DEFAULT and S-1-5-18 from Guest to Admin Then I enabled System restore & created today as Restore Point & then restore to an earlier operating state today. Nothing changed. I still have to wait about 5 min for everything to load properly & be able to look at HDDs & go on to the Internet. I bet I still would have problems installing Zone Alarm Pro. So what is plan B (change of plans)? I request step by step instructions without messing any further.
