Hi all. I did search for this issue but the only other report I founds wasn't resolved or explained properly. So here's some background:
I'm running an HP dv6-6080 with Intel HD3000 graphics and an AMD Radeon 6770M in switchable mode. I've long been using custom drivers for these cards to keep current with the Catalyst releases since HP stopped providing driver updates. However:
In Windows 10 build 10074 (actually started in 10049 but has persisted) I noticed a command script run on every logon. Turns out, it was running a Catalyst Windows Update script which removes any graphics drivers NOT installed via Windows Update (e.g. the ones installed with CIM (Catalyst Install Manager)) and reinstalls, currently, Catalyst 15.20wNxt drivers.
A sample from the log in C:\AMD\WU-CCC2\ccc2_install :
Checking for previous instances of CCC installed through WU.
Check for any CCC instance, installed through CIM.
Found CCC instance installed through CIM.
Successfully uninstalled CCC instance which is installed through CIM. <---here is where my drivers get deleted
got uninstall strings in szUninstallStrings list and passing for uninstallation..
Successfully uninstalled existing CCC from WU using PerformWUCCCUninstall.
This is very frustrating because the 15.20 drivers run my laptop hot and I wish to use the custom 14.4 drivers I had which worked 100% with all builds of Windows 10. Everytime I manually install these drivers they get removed at startup again by the script which deletes the drivers. I've turned off the "Automatically get drivers from Windows Update" option and even deleted the folder C:\AMD\WU-CCC2 but the issue persists: I don't want these 15.20 drivers yet but I can't replace them. I checked MSCONFIG and SERVICES.MSC but can't find the WULaunchApp.exe instance set to run except when it is in execution. Are there any workarounds for this?
