Updating windows 7 32 bit to 64 bit
Instead, to simulate having new license data from Microsoft, I have modified the kernel just enough so that it ignores the two license values that set memory limits, and I have started Windows in Test Mode so that it tolerates a kernel that no longer has Microsoft’s digital signature. I am not solving for you the problem of how to have 32-bit Windows Vista use all your 4GB or more of physical memory without Microsoft’s permission.
That 32-bit editions of Windows starting with Windows Vista are limited to 4GB is not because of any technical constraint on 32-bit operating systems.
No code needs to be changed even by one byte, but to prove this point I have to patch the code because Microsoft protects the data.
If you want that this should work for you without contrivance, then pester Microsoft for an upgrade of the license data or at least for credible, detailed reasoning of its policy for licensing your use of your computer’s memory in 32-bit Windows Vista.
The next picture is as much a record of my unimaginativeness as of 32-bit Windows Vista actually using (very nearly) all the installed 8GB.
An entirely ordinary test program writes 1GB of data from a single memory block to a file and reads the file back into that same memory block. By the time that eight instances are running concurrently, all the physical memory is in use: Of course, there are contrivances and caveats.
