I copied the file shdoclc.dll from system32 to the D: drive under Windows, then modified this file, and then under DOS I tried to copy this file back to the system32 folder, copy d:\shdoclc.dll c:\windows\system32\ /y/h/r/k
but why doesn't it work... XCOPY doesn't work either...

The system protection feature prevents files from being copied into this directory; only under pure DOS or in PE can the copy succeed.

I did the experiment under Airi DOS; isn't Airi's DOS pure DOS?
