The TWCU.EXE or TP-LINK Wireless Client Utility is a configuration application required to run wireless adapters successfully. The TP-LINK Wireless Client Utility application only exists on computers that are using the TP-LINK adapters. Upon the installation of this application, the service will be automatically added to the Windows service list that will continuously run in the background.
The Twcu.exe is placed at the C:\Program Files\TP-LINKTP-LINK\Wireless Utility folder and is used by TP-LINK to connect to the internet. The name of the main executable file is twcu.exe and can be viewed in the Services tab of the Task Manager. If you are one of the users who just upgraded to Windows 10 from the previous Windows versions, then you’ll most likely see an error saying, “Failed to load the library file!” that has something to do with twcu.exe or TWCU. This error pops up when you go to your desktop and every time you log into your Windows 10 PC.
Like pointed out, this error is related to the TP-LINK Wireless Client Utility and every user who is using the TP-LINK Wireless Client Utility is experiencing this problem which may be due to some compatibility issues especially when you start getting this error right after you upgraded to Windows 10.

This option is almost the same as the first one except it is an alternative way of fixing the TP-LINK Wireless Client Utility in case the first one didn’t work. In this option, you will troubleshoot the compatibility issue of the TP-LINK Wireless Client Utility.
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDPSParametersStep 4: After that, look for the “Parameters” registry key and select Permissions. Step 5: Now select your account under Group or user names. Step 6: Next, make sure that the “Full Control” and “Read” boxes are both checked, and then click on the Apply and OK buttons to save the changes. Step 7: Afterwards, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlWDIConfig Step 8: From there, look for the Config key and right-click on it and select Permissions and then click on Add and type “NT Service/DPS in the box and click OK.

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.
Powercfg -requestsoverride Driver "Legacy Kernel Caller" SystemStep 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.
powercfg –devicequery wake_armedAfter you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings
Enter Cooler Master XG850 PLUS PLATINUM, a new, in-house designed power supply from Cooler Master. I will admit that in last years I was a big fan of Cooler Master and their components, well not all but power supply and PC cases were always products from them that I liked and used. The latest power supply from them does not disappoint and I must say that I like it very much, it is hi-quality, it is silent, it has a large LCD display where you can see its current state and also has some RGB lights so it looks cool in your case.
So without further detours here are the technical specifications and then we will talk a little about it.

If we put aside the technical characteristics of the power supply itself we are left with visual and real working experience. Now real working experience will not be covered here since yea it is working great but it needs some time and a long period of testing in order to be able to say that it is indeed reliable and great but considering I have never had any issues personally with power supplies from Cooler Master I will assume that this one is also very reliable and hi-quality.
That leaves us basically with looks and feels of supply itself and I must say that I like it, and I mean I like it a lot. It feels hi-quality and it looks hi-quality. The LCD display is very good looking and it is very crisp and readable. With power supply some proprietary software so you can choose what you want on display on the screen and also you can control RGB and display colors with it.
I have not opened the power supply to see how it looks inside but from what I could see I think this would be my new power supply if I were building a new PC now. I recommend it and if you decide to get it I hope it will serve you long long time.
Thank you for reading and I hope to see you next time.
