It seems to me there is a bug in the new kernel32.dll.
I have tried to find out how to send bug reports to
Microsoft but it seems they do not want me to....
Comments?
Hi Leif,
Kernel32.dll is a crucial file of Windows, and all the system depends on it,
so better not play too much with it....
What Windows uses is the file kernel32.dll found in the Windows\system32 directory. If it gets ruined or erased, Windows
replaces it with the backup copy held in the windows\system32\dllcache directory.
A DLL is loaded into memory when first used, then usually it is erased from memory only when the program that uses it
terminates and some memory is required for other tasks.
So what probably happened in your experiment is that Linrad did load the kernel32.dll *not* from the system32 directory,
but from its local directory, and the CPU load computation was correct. Then when Linrad exited, the copy loaded in
memory was not unloaded, because there were not an immediate need of free memory, so when you restarted Linrad, even if
you had erased the file, the loader did find the copy of kernel32 already loaded in memory and used it, still giving the
correct results. Of course when you rebooted the system, the copy of the DLL found in system32 was that was used.
My suggestion for another experiment is the following :
Rename that kernel32.dll that gives the correct results with another fancy
name, for example mystery.dll
Then place it into the Linrad directory, and change the code so to load
mystery. dll instead of kernel32.dll
So you will be assured that Windows itself will not use it, avoiding in this way any problem of compatibility or
updating, and Linrad only will use it, limited to the CPU load computation functions.
