Filter unserviceable and stale drivers before Win11 Creator injection - #5016
Filter unserviceable and stale drivers before Win11 Creator injection#5016mewclouds wants to merge 3 commits into

…ection Add-Driver aborts the whole batch when one exported package is bad, which broke ISO creation for anyone with an Extension-class or stale duplicate driver in their store (ChrisTitusTech#4971, ChrisTitusTech#4982). Exclude both before the single Add-Driver call instead of guessing per-vendor.
📝 WalkthroughSummary by CodeRabbit
WalkthroughDriver staging now recognizes quoted extension classes, preserves packages from different providers, validates WIM metadata before injection, and skips image changes when no packages survive. The ISO workflow reports whether drivers were actually injected. ChangesDriver staging
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR filters drivers before offline injection, but valid packages may still be silently dropped when provider tokens resolve differently, and an empty-injection path may report success without adding drivers. Merge should wait for these bounded correctness and reporting issues to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

416-479: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the shared driver-export harness, and assert that excluded folders are deleted.
Two points on the new tests:
- The
dism.exestub and theStart-Processmock are now repeated three times. Move them into a helper inBeforeAllthat accepts the fixture list. That keeps future changes to the DISM contract in one place.- No test asserts that
Add-WinUtilISOStagedDriversdeletes the excluded folders from the export root. That deletion is the mechanism that prevents the DISMAdd-Driverfailure, because the single call uses/Recurseover the whole export root. Capture the export root in the mock, then assert that the excluded folders no longer exist.Also applies to: 481-561

make the comma-separated version component optional, allowing date-only entries
such as DriverVer=06/01/2024; when no version is captured, assign the default

Accept date-only DriverVer entries instead of treating them as unknown. Use the full folder path as the dedup fallback key so two unrelated packages can't collide on a shared leaf name. Discard the logger's own output inside the selector so an emitting -Log callback can't inflate the survivor count. Skip driver injection instead of failing the whole ISO build when nothing is left to inject. Also extracts the repeated DISM mock setup in the driver tests into one shared harness, and asserts that excluded packages are actually deleted from the export root before Add-Driver runs, not just logged.

Type of Change
Description
Win11 Creator exports every current-system driver, then injects all of them into install.wim in one Add-Driver call. If any single package is bad, DISM aborts the whole batch and the user gets no ISO.
Two real cases cause this:
This PR filters both out before the single Add-Driver call runs. Nothing else about driver injection changes, and WinPE boot-driver staging is untouched.
