it is used by logitech in their 'setpoint' software for keyboards and mouse. I cannot locate it in my sys32/drivers folder either, so i am hunting for it.

something (driver package?) from Vista (vista_rtm.061101-2205) ; i think i installed it with xp SP3
This file prevented my Alps Thinkpad (on a Dell Latitude D630 notebook) from installing the driver (causes a "Fatal Error" during install). Renaming to wdf01000.old will resolve that issue.

Logitech wireless mouse
bsoded my system
Was consuming 100% cpu on a processor. Unused IEEE1394 was running in it and disabling that device via DeviceMgr solved issue.

seems to show up in many bluescreen view reports - driver power state error so i unchecked the power management for authentec fingerprint scanner from
Cisco securityreported that it was monitoring my keyboard.
Start up driver for windows if corrupted needs to be replaced with a copy from a running vista installation the CD won't always fix it
this is common file infected by TR/Rootkit.Gen. If its 100% CPU I guess its active.
It caused a bluescreen. Dell desktop with a dell mouse and logitech Bluetooth keyboard
It monitors the Keyboard, but for what I do not know. My Cisco Security Agent warns me about it all the time.

My computer is having problems with this file and there is no way to fix it, since it is preventing me from reaching the logon screen in my computer.

Best practices for resolving Wdf01000 issues

A clean and tidy computer is the key requirement for avoiding problems with Wdf01000. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Wdf01000.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
