Hello! I recently found out i had a virus on computer and it was starting on startup using the system registry. When i removed it from the registry it reappeared. I figured I could completely deny all of the system's access to the registry which I now realize wasn't a very smart idea. When I try to login now i get a "Unable to log you on because of account restriction.". Even in safe-mode I get this error. Have anyone got any suggestions for me? I'm running Windows XP SP3 and the login is interrupted when a "RPCSS is starting...".1 person needs an answerI do too

Unfortunately you made a bad choice. Not only would what you did not remove the virus, you now have inoperable Windows. First retrieve your data if you don't have good backups by one of the methods at the end of this post. Then try a repair install. If the repair install doesn't work, then you will need to do a clean install of Windows. http://www.michaelstevenstech.com/XPrepairinstall.htm - Repair Install How-To http://michaelstevenstech.com/cleanxpinstall.html - Clean Install How-To http://www.elephantboycomputers.com/page2.html#Reinstalling_Windows - What you will need on-hand 1. Pull the drive and put it in a USB drive enclosure or use a USB drive adapter. Attach this to a computer running a working install of XP/Vista/Windows7. Use the working Windows Explorer to copy the data to the rescue system's hard drive and then burn the data to cd or dvd or copy it to an external hard drive. I prefer not to do this if I know the drive is infected because there is a chance of infecting the host system. In these cases, I use #2 below. 2. You can boot the target computer with a Bart's PE (XP only) or a Linux Live CD such as Knoppix or Ubuntu and retrieve the data that way. Here is general information on using Knoppix for data retrieval when you can't get into Windows: You will need a computer with two cd drives, one of which is a CD/DVD burner OR a USB thumb drive with enough capacity to hold your data OR an external USB hard drive. Download the Knoppix .iso and create your bootable CD*. If you are doing this in an older operating system (XP or Vista), you'll need third-party burning software like Nero, Roxio, or the free ImgBurn (Windows 7 can burn .isos natively). Burn as an image, not as data. Then boot with the CD you created and Knoppix will be able to see the Windows files. If you are using the USB thumb drive or the external hard drive, right-click on its icon (on the Desktop) to get its properties and uncheck the box that says "Read Only". Then click on it to open it. Note that the default mouse action in the window manager used by Knoppix (KDE) is a single click to open instead of the traditional MS Windows' double-click. If you want to burn CD/DVDs, use the K3b program. *If your computer only has one optical drive and you want to use that drive to burn data or need to test the drive, you can create a bootable USB thumb drive running Linux instead of a bootable CD. This website will show you how to do that - http://www.pendrivelinux.com http://www.knoppix.netMS-MVP - Elephant Boy Computers - Don't Panic!

I have Ubuntu installed on my computer too. Is there no way of from Ubuntu to reset the registry settings or do I have to reinstall/repair windows to make it boot again?

There is no way from Ubuntu to reset the Windows registry. Sorry. But you can use Ubuntu to capture your data if you need to.MS-MVP - Elephant Boy Computers - Don't Panic!

Is the "Who is allowed to use registry"-data stored in the registry?

Of course. And you might be able to fix this with a specialized Windows tool like ERD Commander (old and now discontinued; very expensive back in the day) or a current tool not generally available to end users. Or possibly with a Bart's PE. You could post on a Bart's forum to see if Bart's can do this. But you can't do it from Ubuntu.MS-MVP - Elephant Boy Computers - Don't Panic!
