OK, I have jush finished to test PatchPE 1.30 (why not version 1.31, see below) with hexdump for Windows https://www.di-mgt.com.au/hexdump-for-windows.html
By default, hexdump doesn't works on XP:
So, I have patched hexdump with PatchPE 1.30 and that's works :
I have used version 1.30 because version 1.31 doesn't works on XP !
BUT, if you want, you can patch PatchPE 1.31 with PatchPE 1.30 and it will works again on XP :
There is only one disavantage with the version 1.31, now PatchPE need a computer that's support SSE2. It is not the case with the version 1.30.
It seems that PatchPE can be useful in some situations.
