The genuine LSB.exe file is a software component of Lenovo Service Bridge by Lenovo Group. "LSB.exe" is the Lenovo Service Bridge which installs as a startup program on certain Lenovo 32-bit and 64-bit Windows computers (Win 7 and later). Lenovo offers it for download from "support.lenovo.com". It can be uninstalled through the Control Panel's Programs and Features app by selecting "Lenovo Service Bridge." It enhances the user's ability to use eSupport in both directions. It automatically finds and transmits the computer's model and serial number information needed by support personnel, also enabling the support site to branch automatically to the correct information. For product downloads, (e.g., driver updates), the Service Bridge lets the user start, pause, or terminate downloading multiple files at one time. Lenovo, founded in China in 1984 as Legend, known abroad as "Lenovo" since 2003, purchased IBM's Personal Computer Division in 2004 and is now #231 of the Fortune 500.

Best practices for resolving LSB issues
A clean and tidy computer is the key requirement for avoiding problems with LSB. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the LSB.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
