C:\Windows\System32\DriverStore\Temp
Windows stages extracted GPU, chipset, and audio driver packages in DriverStore\Temp during device installation and Windows Update.
How Windows Manages Windows DriverStore Temp & Superseded OEM Packages on NTFS & NVMe Drives
Windows 10 and Windows 11 maintain hidden system directories and root-level allocation files at C:\Windows\System32\DriverStore\Temp to handle shell thumbnail databases, prefetcher launch traces, hibernation power states, and user-profile scratch storage. Because many of these paths are marked with +H (Hidden) or +S (System) attributes or guarded by SYSTEM ACL permissions, standard folder size scans often miss them entirely.
Over time, orphaned temporary files, stale Explorer DataCache_* buckets, and uncompacted virtual storage allocations inside C:\Windows\System32\DriverStore\Temp lock up 1.5 GB – 9.5 GB of primary C: drive space. Cleaning Windows DriverStore Temp & Superseded OEM Packages using the proper administrative method restores drive headroom safely.
