hp desktop pcs, Windows NT workstation 4.0 - the easiest upgrade to Windows 2000 Professional (Microsoft document)

Page 6
Because Windows NT Workstation versions 4.0 and Windows 2000 Professional
share a common registry, file system, security, and operating system kernel
structures, nearly all applications that run on Windows NT Workstation 4.0 will run
without modification on Windows 2000 Professional.
The upgrade process itself is straightforward and in most situations will not require
significant preparation outside of standard lab upgrade testing previously discussed.
Software Compatibility
A few minor incompatibilities exist between versions 4.0 and Windows 2000
Professional. One example is Anti-virus software, which will need to be upgraded
because of its use of file system filters. A large majority of Windows NT Workstation
4 file system filters will not work on Windows 2000 Professional because of updates
to NTFS in Windows 2000 Professional.
It may also be necessary to obtain upgrades for third party network components
(such as TCP/IP stacks) written for Windows NT Workstation 4.0.
Hardware Compatibility
Device Drivers
Almost all peripherals and devices that worked with Windows NT Workstation 4.0
will work today with Windows 2000 Professional. A small set of third party devices
that worked with Windows NT Workstation 4.0 may require new/updated drivers to
be written by their original suppliers to work with Windows 2000 Professional.
File System Support
NTFS v4 will be transparently upgraded to NTFS v5 during the upgrade process.
