Removal of the Windows 2000 RP550/BP550 device driver
files and registry entries

Background

Windows 2000 (W2K) is a plug and play (PnP) operating system and plays

an important role in installing kernel device drivers.

During installation, W2K detects new hardware and starts it’s own

installation program (there is no NT style setup program) which installs the device

driver, including updating the registry, processing user’s response to dialog

box questions and entries in device information files (.INF files).

The .INF files are supplied with the driver. They are ASCII text files and

can be viewed with Notepad. (it’s worth remembering this – you will need it later).

When it comes to un-installation, the PnP philosophy means that the

hardware is simply removed. On restart W2K will not load the drivers and

the device manager entries will not be created. It’s as if the H/W and driver

were never installed.

Later, if the hardware is re-installed, then on restart, the PnP system will

reload the driver, update the device manager and re-create any dynamic

registry entries.

However under certain circumstances it may be necessary to 100% remove

the driver and all supporting files from the W2K system. Here’s how:-

Procedure

Section 1 assume that the H/W and driver are installed and working.

Proceed to direct section 2, if you desire to remove files and registry entries

following an installation problem.

1. Removal of device manager entry

1.1 Start the ‘Device Manager’. The quickest way is to right click on my

computer and select ‘Properties’ from the pop-up menu. When the
‘System Properties’ dialog appears, left click the ‘Device Manager’

button.

The device manager displays device information as a ‘tree structure’. To
expand the entries, click the ‘+’ icon.
