Windows 10 includes (Windows-on-Windows 64), which allows 32-bit apps to run on 64-bit systems. However, the reverse is impossible: a native x64 app like Sxsi will fail on x86 Windows.
To use the media, insert the USB into the target PC and restart it. You may need to enter the BIOS/UEFI menu (usually by pressing F2, F12, or Del
Before delving into SxS, one must understand the problem it solved. In earlier Windows versions (e.g., Windows 95, 98, and even XP without SxS fully enabled), applications relied on shared DLLs stored in System32 . When an application installer replaced a common DLL with an older or incompatible version, previously installed applications that depended on the newer version would crash. This fragility became more pronounced with the advent of 64-bit computing on Windows x64, where the mixing of 32-bit and 64-bit libraries could lead to even more obscure failures. Sxsi X64 Windows 10
You want to delete the WinSxS folder to save space. → Stop. This will break Windows. Use the DISM cleanup commands instead.
In Windows, SxS is implemented using the Windows Side-by-Side (WinSxS) folder, which is a part of the Windows directory. The WinSxS folder contains different versions of DLLs and other system components that can be shared among applications or used specifically by certain applications. You may need to enter the BIOS/UEFI menu
This error indicates that the LoadLibrary function failed because the application’s dependency manifest is incomplete or the required runtime is missing. Common causes include:
If an update is interrupted or a hard drive develops bad sectors, the manifests inside the SxS installer framework can become corrupted. This leads to Windows Update errors (such as 0x80073712 or 0x800f081f ), boot loops, or application launch failures. 3. Side-by-Side Configuration Errors This fragility became more pronounced with the advent
x64 systems can handle more than 4GB of RAM, allowing for smoother multitasking and resource-heavy tasks like retro-system emulation. Compatibility:
This mechanism is why Microsoft Visual C++ applications from the 2005–2008 era depend so heavily on SxS, as their runtimes (CRT, MFC, OpenMP) are deployed specifically as SxS assemblies via the WinSxS store.
The sxsi x64 process on Windows 10 is a powerful, legitimate system component that ensures software from the last two decades continues to run without DLL conflicts. While it can occasionally cause high CPU or memory usage, this is almost always due to corruption or a pending update, not malicious behavior.
