Demetrios13 Posted March 1, 2005 Posted March 1, 2005 My operating system is windows xp professional. I was trying to remove adware from my pc and by mistake I erased a wrong value from the registry. Now I cannot get access in the computer. When I power up the pc the windows seem to load ok but when the welcome to windows screen appears the box where you type the password for the user login is not there, it disappeared. So I cannot type in the password and i cannot open the computer. Is there anything I can do to overide the password screen and go directly into the windows? Before I started "playing" with the registry I made a backup, so if I manage to get into the windows I believe I will be able to restore the damage.
enuffsaid Posted March 1, 2005 Posted March 1, 2005 Try this...At the logonscreen (which doesn't appear), press CTRL-ALT-DELETEClick on the Applications Tab > New taskTry any one of these if not all...logonui.exewinlogon.exeexplorer.exeAnd click OK ofcoarse...If one of these does the trick you may have deleted the relevant registry key. Report back with your results.Good luck.
jaclaz Posted March 1, 2005 Posted March 1, 2005 If you do have a backup if the registry, you can boot with a DOS floppy with this driver:DATAPOL NTFS4DOShttp://www.datapol.de/dpe/prod/508447959013ddf01/index.htmlhttp://www.datapol.de/dpe/freeware/and replace the Registry files with the backup.jaclaz
Demetrios13 Posted March 1, 2005 Author Posted March 1, 2005 Hi thanks for responding. Control ALt Delete does not work it wont do anything all i can do is move the cursor around. Safe mode does not work either since i have still to type the password
enuffsaid Posted March 1, 2005 Posted March 1, 2005 So you're also saying you cant use the keyboard. It's not responding at all? Does the Num-lock button work? (num lock light goes on / off)You could try Winternals Administrator Pack or one of the SuperWinPE bootable CDs that are floating around... Boot from the CD and load the registry hive you've corrupted and replace the deleted entries with the ones from your backup.Can you select "last known good" from the F8 startup options?Cheers.
Demetrios13 Posted March 1, 2005 Author Posted March 1, 2005 the keyboard is working The Num-lock and caps lock buttons work but when I press Ctrl Alt Delete nothing happens. Also I have already tried the last known good configuration still nothing.
enuffsaid Posted March 1, 2005 Posted March 1, 2005 Sorry to hear that, mate.I'm really running out of answers. Looks like you'll have to create a bootable CD like SuperWinPE or Winternal's Admin Tools and edit the registry that way (load hive). There are plenty rescue CD's available. Try here or google for "rescue cd".Hope that helps.
Demetrios13 Posted March 1, 2005 Author Posted March 1, 2005 I will try the botable cds tomorrow, it is weird. Thanks for your replies man
enuffsaid Posted March 1, 2005 Posted March 1, 2005 No problems mate... Goodnight, and keep us posted.eNuffSaid
JGabrius Posted March 2, 2005 Posted March 2, 2005 Do you have Remote Registry Service enabled? Do you have more than one computer on your workgroup?If yes to both, you should be able to power up both computers and edit the bad one's registry from the other PC. That is, if you know what you deleted and you need to fix!
Demetrios13 Posted March 2, 2005 Author Posted March 2, 2005 I dont really remember if i have remote registry service enabled and I have one computer only. Plus i am not sure what I erased, lol
