All user-mode address space above the 32-bit limit is reserved by the system. Some of these DLLs are written to behave differently on WOW64 than they do on 32-bit Windows, usually because they share memory with 64-bit system components. Almost all 32-bit DLLs are unmodified copies of 32-bit Windows binaries, though some are loaded as CHPE for performance reasons.

On Windows 10 on ARM, CHPE (Compiled Hybrid Portable Executable) binaries may also be loaded into an x86 32-bit process.Īt startup, Wow64.dll loads the x86 version of Ntdll.dll (or the CHPE version, if enabled) and runs its initialization code, which loads all necessary 32-bit DLLs. These DLLs, along with the 64-bit version of Ntdll.dll, are the only 64-bit binaries that can be loaded into a 32-bit process. (ARM64 only) wowarmw.dll provides support for running ARM32 programs on ARM64.
