Issue: How to Fix SYSTEM_SERVICE_EXCEPTION (Vhdmp.sys) BSOD on Windows 10?
Hello. This week my PC started displaying a BSOD SYSTEM_SERVICE_EXCEPTION (Vhdmp.sys). I have no ideas what does that mean. The error shows up randomly every two or three days. Has someone else encountered the same problem?
Solved Answer
SYSTEM_SERVICE_EXCEPTION is a Windows specific BSOD, which may show up on any Windows version when one of the core system files is damaged, missing or corrupt. In this case, the culprit of the BSOD seems to be the Vhdmp.sys, which is a driver file known as VHD Miniport Driver. It belongs to the Microsoft Corporation and is digitally signed from Microsoft Windows – Microsoft Time-Stamp Service. Sys files cannot be removed or modified because they are responsible for the correct loading and configuring the Windows OS. Vhdmp.sys file is a part of hardware driver and its task is to ensure the smooth performance of the hardware and devices.
SYSTEM_SERVICE_EXCEPTION (Vhdmp.sys) BSOD may be triggered by many factors, including virus infection, incompatible software, outdated device drivers and various systems’ changes. In most of the cases, the error occurs when the PC’s owner attempts to create file backups, but it may also emerge under other circumstances.
It has been found that the Vhdmp.sys BSOD tends to strike Windows 10 PCs and laptops that run BitDefender anti-virus. Therefore, it’s advisable to uninstall it and check if the problem reoccurs. To uninstall the anti-virus completely, we would recommend using Perfect Uninstaller or another professional software removal utility. If you prefer manual removal, you can find the guide on this page.
As soon as you uninstall BitDefender, make sure that Windows Defender and Windows Firewall are enabled to ensure proper system’s security. If that doesn’t help, we would recommend you to update/reinstall the drivers.
