Yes, but unless all 3rd party drivers can run in userspace (which is not really feasible), Microsoft needs to give vendors the option to install a kernel driver, at which point a vendor can always decide to ship a kernel driver and bypass any restrictions.
replyImo, the only thing Microsoft can meaningfully do here from their side is threaten LG with pulling all their drivers if they keep doing this.
Drivers still need to pass certification & get signed. Microsoft does get to reject them.
replyI can't imagine the group doing this validation is sufficiently manned/funded; it's a cost centre, and the effects of cutting it don't show up for years.
I expect that process to be mostly automated, I wouldn't expect the MS folks at the testing lab to do much (if any) manual testing, especially for a new version of a previously approved driver.
replyI'm not surprised that the driver got approved, especially if the previous versions already had some user UI and this update "just" added the ads. What I would hope now is for MS to either pull the updated driver or ask LG to roll the change back themselves, possibly under the thread of pulling their drivers altogether (iirc they done that with other companies in the past).
