Assumption: you mean enabling/installing side-by-side (SxS) assemblies and x64 support on a 64-bit Windows 10 system (e.g., to run x64 apps, libraries, or install Visual C++ Redistributables). If you meant something else, tell me the exact feature name.
This tells you exactly which assembly and version is missing.

The query specifically mentions "updated." The SxS architecture is central to how Windows 10 handles its cumulative updates:
Users searching for "sxsi x64 windows 10 updated" typically face one of these scenarios after running Windows Update:
These errors emerge because an update may have partially applied, a manifest file got corrupted, or a version reference used by your app is no longer present.
On an x64 system, Windows maintains separate SxS manifests for 64-bit and 32-bit assemblies. The folder names include amd64 (for native 64-bit) or x86 (for 32-bit within SysWOW64). If you attempt to run a 64-bit application that depends on a 32-only SxS component, it will fail—even if the DLL names match. This is a common source of errors after updating Windows 10.
On an x64 Windows 10 system, the main SxS folder is:
C:\Windows\WinSxS
For 32-bit applications running on x64 (via WoW64), Windows also maintains:
C:\Windows\SysWOW64
But the true heart of SxS is WinSxS. This folder contains multiple copies of the same library under different version-named subdirectories, such as:
