Lsass.exe is a program that tracks user logons to the PC. When a logon is validated by lsass.exe, it generates a user token which is then assigned to programs that are run under the login. Normally this is done automatically and you won’t notice a thing. But there are times when you might get an error message containing lsass.exe. When this happens it means one of two things.
Either you have a problem with your registry, or you have downloaded a virus. Both of these can cause major problems for your computer. The good news is that they can be fixed, and the fix for either of these problems involve maintenance that should be done on your computer regularly.
The first step you need to do when faced with an error message involving lsass.exe is to scan your computer for viruses. There are any number of different programs that will do this, and most will walk you through the process. It is important that you scan your computer for viruses on a regular basis. The lsass.exe error is not the only problem that viruses can cause if they are able to infect your computer. The only way to avoid these viruses (and the problems that come with them) is to scan for viruses on a regular basis.
Once your computer has gone through the scanning and virus removal process, it is time to fix your registry. If you are using a computer with Windows, you have the option of cleaning up your registry with the program regedit, which is the default registry editor. This should only be done by someone who is very experienced with computers though. If you make the wrong changes to the registry you might have to reinstall the entire operating system. Thankfully, for those of us who aren’t professional programmers, there are applications which will clean up your registry and fix your lsass.exe problem automatically.
These programs will also walk you through the process, and It is just a matter of answering a few basic questions, and letting the program do it’s job. One word of caution, if you are asked by the program whether you want a backup of your registry to be made or not, always say yes. Most programs will do this automatically, but you always want to have a backup in case the changes created more problems.
After the virus scan and registry cleaner have both finished, it is time to restart your computer and make sure that the lsass.exe problem has been fixed. You may have been prompted to restart your computer when the virus scan was completed. You can restart then if you want, it won’t do any damage. It is very important that you make sure to restart your computer after the registry cleaner is finished though. Restarting the computer is how you allow it to make the changes that you wanted it to make.
You won’t be able to see if the lsass.exe problem has been fixed until after you restart your computer. Remember, the key to avoiding this and many other issues is to do regular maintenance on your computer.
