Broken registry, can't access login screen
After a recent registry blunder, I found myself on a completely black screen with only the mouse visible instead of the login screen. Using a live CD, I fixed the registry; namely, /HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/Lsa -> Authentication
Packages. However, I still have the same issue on startup. Is there a way I can fix this, or barring that, restore the registry without booting? I don't have any Windows installation media.
OS: Windows 7 Professional x86
Live CD used: http://www.pcregedit.com/
Keys to the Problem Broken registry, can't access login screen
Whoops, for some reason I didn't see other answer results before. I successfully used System Restore (F8 on startup) to fix the problem.
How to Avoid Downloading Malware
Where are you getting the download?
There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.
Don't install download manager
Many sites suggest or require you to install an installer or a download manager before allowing you to download a program you may be interested in downloading. These tools almost always cause your computer more problems and may even have malware or other spyware. Avoid any site claiming anything must be installed first before you can continue with your download.
Avoid advertisements on download pages
To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.
Cancel or deny any automatic download
Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
