Udedenkz Posted December 14, 2009 Share Posted December 14, 2009 I just messed something up with Explorer and System Restore didn't fix it. So I rebooted in last know good configuration. I managed to get to a cursor, then it crashed. Same with safe mode. So pretty much Last Know Good Config made my system unusable. Got it to work by running System Repair Disk from a USB Thumbdrive. Now I gotta go back to fixing the original problem! Link to comment Share on other sites More sharing options...
halcyoncmdr Posted December 14, 2009 Share Posted December 14, 2009 I've had systems where I had to try Last Known Config 3-4 times before I got a usable system. I didn't change anything in between, just did it multiple times one after another when it didn't boot each time. Link to comment Share on other sites More sharing options...
Udedenkz Posted December 14, 2009 Author Share Posted December 14, 2009 There is great reason in keeping a variety of backups because, System Restore - Doesn't Always Solve The Problem (Even If Problem Happened After System Restore Point) - W7 will delete all restore points if space is limited Last Know Good Config - Explained Above. I am going to see if a registry backup going to fix my issue. :) Link to comment Share on other sites More sharing options...
Xilo Posted December 14, 2009 Share Posted December 14, 2009 Honestly, that's why you should never try to tweak stuff all willy nilly. Stuff breaks. Link to comment Share on other sites More sharing options...
Udedenkz Posted December 14, 2009 Author Share Posted December 14, 2009 Honestly, that's why you should never try to tweak stuff all willy nilly.Stuff breaks. That is one of the fun things about tweaking. Although I doubt it is related as I stay away from messing with System Restore and so on. Those are a must!!

Xilo Posted December 14, 2009 Share Posted December 14, 2009 Stuff breaking and spending hours fixing it doesn't really sound like fun. I like to actually use my computer. But that's just me... Link to comment Share on other sites More sharing options...
StealMySoda Posted December 14, 2009 Share Posted December 14, 2009 To be honest I think it's the fact that you messed something up in Explorer, not the fact you tried to use 'last known good config' that caused your computer to crash. Link to comment Share on other sites More sharing options...
Tews Posted December 14, 2009 Share Posted December 14, 2009 To be honest I think it's the fact that you messed something up in Explorer, not the fact you tried to use 'last known good config' that caused your computer to crash. Another reason to keep up to date system images ... It cures a lot of ills.. Link to comment Share on other sites More sharing options...
Guest xiphi Posted December 14, 2009 Share Posted December 14, 2009 Considering this post, I'm not at all surprised. Link to comment Share on other sites More sharing options...
Udedenkz Posted December 14, 2009 Author Share Posted December 14, 2009 Restored a registry backup. Everything works now. To be honest I think it's the fact that you messed something up in Explorer, not the fact you tried to use 'last known good config' that caused your computer to crash. You can delete explorer.exe and your system will still boot. Sorry but anything relating to explorer.exe will only effect your GUI / Usability - your system will still be bootable. EDIT: The LsaLookupOpenPolicy call failed with the following error: %%-1073741822 This is the culprit. Whatever it is. Link to comment Share on other sites More sharing options...

Rohdekill Posted December 14, 2009 Share Posted December 14, 2009 why not just boot in safe mode and undo what you did? Link to comment Share on other sites More sharing options...
Udedenkz Posted December 14, 2009 Author Share Posted December 14, 2009 why not just boot in safe mode and undo what you did? Because after Last Know Good Config, I couldn't boot past the login screen in Safe Mode. Link to comment Share on other sites More sharing options...
Brandon Live Veteran Posted December 14, 2009 Veteran Share Posted December 14, 2009 Last Known Good basically goes back to previous hardware / driver settings, and can be useful if you install a bad driver that breaks boot-up (like, say, if you disabled your AHCI / IDE driver or something). Reverting to Last Known Good won't magically fix all problems, and will make things worse if your LKG configuration was actually meant for different hardware...

Chrysalis Posted December 15, 2009 Share Posted December 15, 2009 last known good config is something that has saved my ass quite a few times, it has quite honestly never failed me. Link to comment Share on other sites More sharing options...
