With the advent of and modern Windows 10 updates, Microsoft solidified the WinSxS folder (located in C:\Windows\WinSxS ) as the definitive solution. Instead of a single copy of a DLL, WinSxS stores multiple versions and variants (x86, x64, debug, retail) of the same system library side-by-side.

While this storage consumption is normal behavior, users with limited hard drive space or smaller Solid State Drives (SSDs) frequently look for ways to optimize it.
The /ResetBase switch removes all superseded versions of every component, preventing the uninstallation of any currently installed updates. This can free a significant amount of space but should only be done on a stable system where you don't anticipate needing to roll back a recent update. sxsi x64 windows 10 updated
