Supports fingerprint scanners on, e.g., Toshiba laptops.

It is the Protector Suite fingerprint reader software. Essential if you want your fingerprint reader to work. Standard on Sony Vaios with fingerprint reader.
It's meant to be harmless software, but certain versions of it have a memory leak and will continuously eat RAM until you kill the process.
For you fingerprint recognition pad
useful for fingerprint, but requires 50%of processor after upgrade of Firefox
It is not essential for the fingerprint reader to work. The fingerprint reader will still work when you lock your computer. This application must have something to do with using the fingerprint reader for security during normal operations. It takes up too much memory, though. The app takes 3 GB DDR2 RAM on my Dell.

Best practices for resolving psqltray issues

A clean and tidy computer is the key requirement for avoiding problems with psqltray. 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, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
