What is esrv.exe?

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.

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, 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.
