Guest rseaton Posted September 17, 2008 Posted September 17, 2008 Hi, I believe I've deleted the 'upperlimit' value in the registry for my keyboard (I was trying to do so for my CD drive, following a knowledge base article). Now, when my computer boots up, I can't log on as the keyboard won't work. It still functions in the BIOS. I'm using XP, SP3 on a Dell Dimension 3000. I have a (slightly old) back up of the registry on my hard drive, so I can copy and paste the correct value over if only I could log on. It's a bit Catch-22. Thanks in advance for any help you can give.

You might need to do a manual system restore, adapting parts of the procedure here: http://support.microsoft.com/kb/307545 Use a Linux boot CD, recovery console from your XP CD, or host the drive on another system. If you've got another system and they are networked, you can also try loading the registry from the other system. Open Regedit., then choose File, .Connect Network registry, and then enter the name of the PC in question. Does adding another second keyboard, USB or PS/2, help at all? Finally, if you can't log on because the keyboard won't allow you to enter the password, you could use one of the Linux-based password removal CDs, clear the PW and then you can use your mouse to get in and use System Restore. If you are using XP Pro and there is the slightest possibility that you've invoked encryption, do NOT do this. Or, launch in Safe Mode and use the Administrator account which often has no password - this is particularly often the case with XP Home. HTH -pk
