We received a letter; our reader wonders whether there is any disadvantage in running a 32-bit operating system on a 64-bit computer.
Another important part of development is related to software compatibility. One of Microsoft’s priorities is the user-level compatibility of their various operating systems. The new operating systems are, at the user level, backward compatible with software released before. New user software, however, cannot necessarily be run on former generations of operating systems.
Therefore, 64-bit enabled computers mean that we have to renounce certain functions, but this does not stem from the 64-bit capacity, but rather from the development of the hardware. The options of 64-bit computing have been well prepared. PCs nowadays are mostly 64-bit capable in the terms of hardware, running a 32-bit software environment. So, if this had been a problem indeed, it would have come to light very soon.
