file redirection

Microsoft does not produce a 32-bit edition of Windows 11 but supports 32-bit applications through two system folders: System32 for 64-bit files and SysWOW64 for 32-bit files. The WOW64 file system redirector directs 32-bit applications to SysWOW64 when they request System32. On a Windows 11 26H2 system, both folders contain kernel32.dll, but the files differ in size. The System32 folder contains files corresponding to the operating system's architecture, while SysWOW64 is reserved for 32-bit applications. A 32-bit process cannot load a 64-bit DLL, necessitating the WOW64 redirection. There are six subfolders within System32 that 32-bit applications can access without redirection. Microsoft has announced that 32-bit Arm applications will no longer be supported on Arm PCs, and only x86 applications will continue to operate through Prism emulation.
