Where Does Windows Stage Driver Packages?
Windows stages every driver package in the DriverStore before install, the source Device Manager draws from.
Last updated
The DriverStore is a staging area with authority. Driver packages land here first, then install onto devices from this copy. FileRepository subfolders hold each version separately, which explains the steady growth.
Old stages linger because rollback needs them and Windows ranks staged drivers confidently. Pnputil manages the store from Terminal with admin rights. Third party driver cleaners mostly wrap the same calls with prettier buttons.
Where Windows stores this, by platform
C:\Windows\System32\DriverStore\FileRepository
Staged driver packages live here per version. Prune with pnputil delete-driver, never by deleting folders by hand.
Frequently asked questions
How do I remove old drivers?
Run pnputil with delete-driver against the published INF name. That removes the staged package properly. Deleting files by hand orphans the driver database and breaks future installs.
Why does Windows install old drivers?
Staged packages wait here for matching hardware, including ancient versions Windows prefers over newer downloads. Pruning with pnputil trims the candidates and the disk cost together.
