Driver.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the operating system, hardware etc.The free file information forum can help you determine if driver.sys is a Windows system file or if it belongs to an application that you can trust.
Description: Driver.sys is not essential for the Windows OS and causes relatively few problems. Driver.sys is located in the C:\Windows\System32\drivers folder.The file size on Windows 8/7/XP is 7,218 bytes. The driver can be started or stopped from Services in the Control Panel or by other programs.There is no file information. The program is not visible. The service has no detailed description. Driver.sys is not a Windows core file.driver.sys appears to be a compressed file.Therefore the technical security rating is 54% dangerous, however you should also read the user reviews.
If driver.sys is located in a subfolder of "C:\Program Files", the security rating is 40% dangerous. The file size is 9,472 bytes.The program has no visible window. The service has no detailed description. Driver.sys is not a Windows system file.driver.sys appears to be a compressed file.

Is it legal to keep windows driver sys file outside of system32\drivers directory? It appears that it is possible if a driver is "manually" configured via CreateService with absolute path to the driver.sys file. However when INF file is used to install the driver using InstallHinfSection and driver location is other than system32\drivers InstallHinfSection will fail with error
SYS issues related driver.sys can be attributed in most cases to a missing or corrupted DOS & Supplemental Programs device driver or faulty hardware, leading to a "blue screen of death" (BSOD) error message. Ordinarily, installing a new version of the SYS file will repair the problem creating the error. Also, maintaining updated device drivers can help in preventing SYS-related errors, so we highly recommend running a driver update scan on a regular basis.
Even though most problems related to errors assocated with driver.sys should be fixed if placed in the correct directory, you should carry out a quick test to confirm. You can then re-open DOS & Supplemental Programs to see if the error message is still triggered.
Driver.sys errors that cause a Blue Screen of Death often follow new installation of software (DOS & Supplemental Programs) or related hardware. Ordinarily, driver.sys-related Blue Screen errors happen when a IBM Corp.-related device driver is loaded, during the install of DOS & Supplemental Programs or related program, or while Windows is starting or shutting down. Keeping track of when and where your STOP error occurs is a critical piece of information in troubleshooting the problem.Notating when driver.sys STOP errors happen is paramount in finding the cause of the DOS & Supplemental Programs-related problems and reporting them to IBM Corp. for help. 041b061a72
