While Core Isolation or Memory Integrity helps protect the PC, enabling it may prove challenging to many. At least that was the case with us, and Windows Security listed HtcVComV64.sys as the incompatible driver.

In such cases, uninstalling the problematic driver is the best course, but not unless you know what the driver does. As for HtcVComV64.sys, it’s a USB Modem driver from HTC Corporation and is not critical to the effective functioning of the PC. So, uninstalling HtcVComV64.sys will cause no harm!

If you can’t find the device that employs the HtcVComV64.sys driver, show hidden devices in the Device Manager. Some devices that are no longer connected but still have related entries in the Registry or driver files are hidden to unclutter the interface.

Also, you could use an effective driver uninstaller software to completely remove all traces of the driver.

2. Via Command Prompt

1. Press Windows + S to open Search, type Command Prompt, right-click on the relevant result, and select Run as administrator.
