The genuine esrv.exe file is a software component of Sony® VAIO Care by Sony Corporation. This driver file works with "esrv_svc.exe" as part of Sony Corporation's "VAIO Care" software for its VAIO laptops. They are related to monitoring power usage and have an effect upon whether automatic screen brightness adjustment works properly, especially after entering and leaving hibernation. (Updating all drivers before upgrading from Win7 to Win8.1 is essential.) If this program does not reside in "C:\Program Files\Sony\VAIO Care", possibly with a subfolder named "esrv", or if it is found in "C:\Windows" or its "System32" subpath, it is possibly disguised malware. Uninstalling is possible via the Control Panel, (select "VAIO Care"). There may be similar processes in other OEM's computers based on Intel's Energy Checker SDK (System Development Kit) with an "ESRV" tool for taking readings from onboard power analyzers, although this was being called "Whatif" software in 2010 and forum threads were archived.
ESrv stands for Sony® Energy Service

This is a product from Intel and the program scans and analyzes your computer so they can make better products in the future with that information matt the helper man :D (further information)
If you have Intel Driver Update Utility installed, uninstall it and the error would go away... If you know your way around the Registry Editor, manually delete all Intel Driver Update Utility. ObiwanRei
Intel Driver Update Utility
This must be what causes my screen brightness to be a bit high after coming out of my screen saver as I am having errors with it.
its not a needed process, it comes with the intel service application, i had just the error after installing that for checking updates.. Lugulbanda
Thanks for the information on this. I see it as an error message popup that says it did not start. I went into Administrative Tools/Services and changed it from Automatic startup to Manual. If I need it, I can start it myself. Ben Vending Rodrguez

Best practices for resolving esrv issues
A clean and tidy computer is the key requirement for avoiding problems with esrv. 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 esrv.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.
