64-bit and 32-bit Windows operating system

[leo]

Hi!

Can Windows 64-bit OS fully support all 32-bit application? Any
restriction? How can 32-bit application execute on Windows 64-bit OS?
By emulator or new technology? Thx!

Hi!

No. Most do work, but by no means all.

Any restriction?

Not sure what you mean.

How can 32-bit application execute on Windows 64-bit OS?

By emulator

Small emulation program, most is native to the CPU.

or new technology? Thx!

There is a lack of driver support for 64-bit compared with 32-bit, partly
because 64-bit requires signed drivers and low priced or free programs and
hardware won't spend the money.
