Using WinDriver with Windows 2000 Service Pack 3

Versions 5.0.5 and earlier of WinDriver do not support Windows 2000 Service Pack 3. Installing the windrvr.sys driver from these versions on a Windows 2000 Service Pack 3 machine, or upgrading to Service Pack 3 on a machine that has the windrvr.sys driver installed, may result in a system crash, and you may need to reboot the PC in DOS mode and rename windrvr.sys to be able to boot Windows successfully.

WinDriver 5.0.5b solved this problem, and it is highly recommended to use this version or later if you have a previous WinDriver version installed. WinDriver v5.0.5b was released shortly after Windows 2000 Service Pack 3.

What to do if I installed Service Pack 3 and Windows produces a blue screen during boot?

  1. Boot the machine in Safe Mode (as administrator) or with the MS-DOS boot diskette.

  2. Erase windrvr.sys from the WINNT\system32\drivers directory.

  3. Reboot.
    If you chose to boot in safe mode to erase windrvr.sys, after the first reboot you will still see the blue screen, but a second reboot should resolve the problem.

  4. Install windrvr.sys from v5.0.5b (or later) of WinDriver, as explained below.

How to upgrade my existing WinDriver driver in order to use it with Windows 2000 Service Pack 3?

You can either upgrade to a newer WinDriver version, or just replace your existing windrvr.sys driver with the one from version 5.0.5b, as explained below. After upgrading the driver, you can safely install Windows 2000 SP3.
  • To upgrade to a newer version of WinDriver (v5.0.5b or above):

    1. Uninstall your current WinDriver version according to the documentation instructions in the User's Manual for this version.
      Note: During the un-installation, be sure to erase the windrvr.sys driver that you have been using from Windows 2000's drivers directory (WINNT\system32\drivers).

    2. Download the latest WinDriver version from the Downloads Page on our web site, and install it according to the WinDriver Windows Installation Instructions. To install WinDriver on a target machine, follow the driver distribution instructions in the User's Manual of the version that you have downloaded.


  • To simply replace your current windrvr.sys driver with the patch from version 5.0.5b:

    1. Contact Jungo's technical support and request to receive version 5.0.5b of windrvr.sys.
      .
      NOTE: To receive the driver you must show that you had a valid upgrade & and support subscription for your WinDriver version when Windows 2000 Service Pack 3 was released.

    2. Erase your existing windrvr.sys driver (from v5.0.5 or earlier) from the WINNT\system32\drivers directory.

    3. Copy the v5.0.5b windrvr.sys driver that you received to the Windows drivers directory — WINNT\system32\drivers.

    4. Reboot to install the new driver.

      You can verify that the driver has been installed successfully by looking at the file's Version details after the installation: Locate windrvr.sys in the WINNT\system32\drivers directory, right-click the mouse and select Properties --> Version. The "File version" should be "5.0.5.1" or "5.0.5b" and the "Description" field should indicate that you are using version 5.0.5b.
