ftdibus.sys driver preventing Windows 11 Memory Integrity

Due to a program I’ve installed for a project my Windows 11 machine was no longer to protect the memory, and I finally did some work to remove the issue.

The issue was a ftdibus.sys driver installed by one of the tools for device I use in projects. I’ve never removed a .sys file before, but some quick googling and I found this Microsoft post that lead me to the answer.

Read the post and it will help you through uninstalling the offending driver.

The version of the FTDI driver was preventing the protection from working and I found the CDM Uninstaller here: ftdichip.com/utilities/#CDMUninstaller (NOTE: this link doesn’t take you directly to the CDM Uninstaller, so you’ll have to search for it on the page. The link leads to you download this tool: https://ftdichip.com/wp-content/uploads/2023/11/CDMUninstaller_v1.5.zip

That page provides a link to the Read Me file which is here: https://ftdichip.com/wp-content/uploads/2023/11/CDM_Uninst_GUI_Readme.pdf

Good luck
