GPU Driver Version History
How the Windows Driver Store retains graphics packages, what rollback changes, and why application profiles and DCH apps may persist separately.
A graphics driver release spans kernel, user-mode, API, audio, profile, and control-application components. “Rollback” can refer to different subsets of that stack.
Topic 1
Driver Store history
Windows may retain a previous signed package after replacement. Device Manager can select that staged package again when rollback metadata exists. Storage cleanup or package removal can eliminate the local predecessor and make the button unavailable.
Topic 2
Graphics package boundaries
Display miniport, user-mode DirectX and Vulkan drivers, HDMI audio, PhysX or compute components, and a DCH Hardware Support App can have separate package identities. Their visible version numbers do not always move together.
Topic 3
Profiles and symptoms
Shader caches, game profiles, application settings, and firmware remain outside a simple device-package selection. A behavior change after a release can arise from any of these interactions, so version correlation alone does not identify a single cause.
