The Microsoft Windows operating system exhibits a graphical user interface which made its first appearance in 1985. It was developed as an easier way for users to operate their machines. All operating systems function as an interface between machine level language and user level software applications. Microsoft, founded by Bill Gates and Paul Allen in 1975, is the world's largest software maker with respect to revenue. Microsoft is best known for Windows.

Important: You should check the hidserv.exe process on your PC to see if it is a threat. We recommend Security Task Manager for verifying your computer's security. This was one of the Top Download Picks of The Washington Post and PC World.
The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active hidserv process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the hidserv.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.
A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
