Hi
I have had some problems of high latency Dpc on my pc because of a Wd01000.sys file. I made a fresh installation of windows 10. All drivers are recent my PC is connected directly to the wall and the problem continues. below this the link speccy

Can you please help me .

Thanks in advance
 
Hi Slamory ... and welcome to the forums ...

First of all, thank you for providing the system information using Speccy. Handy little program, that one is.

Wdf01000.sys Latency
I believe the driver we are investigating is the Wdf01000.sys, we were just missing a letter. The "Wdf" portion of the filename refers to the "Windows Driver Framework" - you can think of it as a "helper" component, it can be "called" or used by other drivers, most often by input/output devices like mice, keyboards, biometric devices, usb devices of many sorts - audio, video, capture, etc....

First Steps
Let's start by updating a few drivers that likely make use of Wdf01000.sys. Your mouse & keyboard.
Mad Catz R.A.T.3 mouse = the current driver is from September 9, 2012, so let's update it to the December 8, 2015 Windows 10 compatible driver. You can get it directly from Mad Catz. On their site, select Windows 10 64 bit, select your model mouse, and then press Download. It should provide you with the driver version 7_0_45_2 file version 4.0.100.1190 and weigh in at 6.01 MB. Mad Catz | Downloads
Microsoft Sidewinder x4 keyboard = your current MS Sidewinder x4 driver is from December 12, 2013, so let's update it to the December 10, 2015 Windows 10 compatible driver. On their site, select Windows 10 64 bit, and you should see the "Mouse and Keyboard Center 2.7 64-bit (EXE)? appear: you can then click the Download button. When downloaded, it should have the file-name MouseKeyboardCenter_64bit_ENG_2.7.133.exe and weigh in at 41.9 MB. Software Downloads: SideWinder X4 Keyboard

Biometric Devices & Windows Services

You have several services and processes running from startup to shutdown on your system, that cater to biometric devices. A while back, Intel bought McAfee - and your system has an odd mix of two of their products: True Key and Safe Key. Safe Key is no longer supported, especially for Windows 10. It's a bit of a mess, but not unmanageable. I counted two or three services running for these, as well as some startup process (not running as services). I recommend that you uninstall them completely, at least during your latency testing. You can always try re-installing them later on if they prove essential to your computing happiness...

If you have a fingerprint sensor, and aren't using it all and never intend to (a fine choice in my opinion), then just uninstall 'em and clean up after 'em. I'll get to the "clean up after 'em" part later on.

I don't have a high opinion of biometrics on PCs ... the drivers remind me of when hibernation first came to PCs: things just weren't ready for prime time. The devices can be balky and stubbornly refuse to recognize things, even when set up following the given steps. Some day, the drivers and devices will be mature enough to recommend. I'm not certain that time has come yet.

If you are currently using Windows 10's "facial recognition" to login, I recommend changing to a password or PIN until latency testing is through.

After you uninstall your biometric device (or disable it, in Device Manager... you might also want to make it "disappear" if it can be disabled in the Bios of your motherboard) make sure that it's associated programs are uninstalled from Programs and Features in the Windows 10 Control Panel. Check in the "Services" module of "Windows Administratve Tools" (available on the Windows 10 Start Menu - All Apps) to make sure that any leftover services from a less-than-complete uninstall are set to "Disabled". These are "Intel Security True Key Service Helper", "Intel Security True Key", "Intel Security True Key Scheduler", "Intel Biometric and Context Agent Service", and "McAfee True Key Service".

Avast Antivirus
I've attached a document to this post, that describes my recommended settings for Avast Antivirus. By strengthening some of the settings for various "Shields", you can greatly enhance Avast's effectiveness. It is a very thorough scanner, but comes with some settings set a bit too lax for my security-minded ways. Have a look, make the settings changes, and know that you just upped a very good antivirus to "outstanding" status.

Programs to Remove Entirely
Because you have Avast Antivirus, you need to remove some other programs that are not only redundant, they can cause clashes in the background as the too-many protectors all clamor to scan the same files. This is not to say that the following are "bad" programs. They are just incompatible. [I have to admit, though, that I class most of IOBits offerings in the not-very-good category].....
Uninstall SpyHunter4, SpyBot (all incarnations and flavors), SlimCleaner (part of Slimware Utilities), and Driver Booster. The first two are completely redundant, and have no business running from startup to shutdown (which they do). SlimCleaner is more of a risk than a help, and runs constantly. Driver Booster hasn't done its job at all .... your drivers weren't up-to-date after all were they? I have NEVER recommended any automatic driver installation tool, these are just the worst. Wasting resources, too. What they are good at: they are a good source of errors. Humor me, and at least uninstall these for now. I'd recommend that they stay uninstalled, but it's your computer, you get to decide.

Services
For some reason, the "BITS" service (Background Intelligent Transfer Service) on your computer is turned off. It's default is "Automatic - Delayed Start". I recommend that you change it back to the default. There are other services that depend on BITS to be running (Windows Update for one, but there are others).

More drivers worth looking at
Depending on how things go with these first steps, we might later have to look at some other drivers as well. If you want to be thorough right away, you could check in on the ASMedia 106x SATA Controller, the ASMedia USB 3.0 extensible controller, and your Realtek audio drivers ... to make sure they are all in their most recent Windows 10 incarnations. If any of these came onto your system via a "driver disk" meant for an earlier version of Windows, uninstall the drivers, and let Windows 10 redetect the devices and install drivers from its Windows 10 driver libraries. You also might want to look at a driver/service running on your system called "NIHardware.exe" or the "NIHardware Service"... it is from "Native Instruments" and is associated with game/media controllers (Cakewalk's Guitar Rig is one example) ... but if you don't have a hardware controller that requires this, by all means disable its service (in Administrative Tool's "Services")... and uninstall any no-longer-used program that might be associated with this.


This post is a bit long, so why don't I give you a break, and stop typing now.
Cheers

Hi
Thanks for the extensive advice you gave me. I will see all the points one by one to see if it disappears latency I have been feeling .The process described me NIHardware.exe " or the " NIHardware Service is because I play electric guitar and got the guitar rig 5 program to serve as an amplifier for guitar.Now one last question where I can see the described BITS process? i cannot find it
 
Hi again

I think that the Native Instruments program module is known to usually behave itself fairly well ... what I hear is that when it causes trouble, it is easy to fix = usually with an uninstall of an older version & installation of a newer (and often, simply reinstalling the same version can fix things, too)...

When I refer to BITS, I'm using an acronym. It stands for "Background Intelligent Transfer Service", and you can change it's Startup back to Automatic - Delayed Start using the "Services" component of "Windows Administrative Tools". It will be listed by that longer name (not by the acronym BITS)...

1) Click on the Windows 10 Start Menu icon
2) Select All Apps
3) Scroll down the list, and select Windows Administrative Tools
4) Select Services
5) From the list of Services displayed, right-click Background Intelligent Transfer Service
6) Select Properties
7) From the General tab, in the drop-down menu for Startup Type, select "Automatic (Delayed Start)"
8) Select OK to save the change and exit.

I'm hoping the new drivers for your mouse and keyboard, and the slimming down of possible antimalware background conflicts, will help with the audio issues.

Cheers
