WinSxS DLLs are found via find_actctx_dll(). When activation contexts are inactive, GetModuleHandle() shouldn't find WinSxS DLLs with the same base name of a normal DLL.
-- v2: ntdll: Exclude SxS DLLs when finding a DLL with its base name and no activation contexts. kernel32/tests: Add more GetModuleHandle() tests for WinSxS.

SxS DLLs are found via find_actctx_dll(). When activation contexts are inactive, GetModuleHandle() shouldn't find SxS DLLs with the same base name of a normal DLL. Whether a DLL is a SxS DLL is marked by the LDR_REDIRECTED(0x10000000) flag in LDR_DATA_TABLE_ENTRY.Flags. Manual testing also shows that LDR_REDIRECTED is not present for DLLs redirected via the API set mechanism. --- dlls/kernel32/tests/actctx.c | 3 --- dlls/ntdll/loader.c | 39 +++++++++++++++++++++++++----------- 2 files changed, 27 insertions(+), 15 deletions(-)

You could probably break out right here.
