Safely reclaim 10–45 GB from orphaned Windows Update staging, WinSxS\Temp\PendingDeletes (the 8.63 GB 24H2 bug), Delivery Optimization, and C:\ProgramData\Package Cache while protecting OS-critical binaries.
Pre-loaded with the default Windows 10/11 cache directories for Windows 11 24H2 Update Cache, WinSxS & Package Cache. Paste your own paths or click Audit Paths Now to verify deletion safety:
C:\Windows\WinSxS
C:\Windows\WinSxS (Windows Side-by-Side Component Store) contains the master files for every Windows 10 and Windows 11 system component, cumulative update rollback package, and optional feature. While many files appear large due to NTFS hard links, superseded Windows Update packages genuinely consume 6 GB to 20 GB+ of physical disk space.

C:\ProgramData\Package Cache is used by the Windows WiX Burn bootstrapper to store cached .msi and .cab installer baselines for Microsoft Visual C++ Redistributables, .NET runtimes, Visual Studio, and third-party drivers. Over years of updates, dozens of superseded versions accumulate.
View Detailed Folder Safety Guide →C:\Windows\SoftwareDistribution\Download
Windows Update downloads compressed cumulative updates and feature packs into C:\Windows\SoftwareDistribution\Download before installing them.
View Detailed Folder Safety Guide →C:\Windows.old
When Windows upgrades to a major new version or build, it saves a complete backup of your previous OS files in C:\Windows.old so you can roll back.
