How to Fix QTCF.dll Error

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue. In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state. Step 1: Find out what’s keeping your computer from going to sleep. To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep. To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:

“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" System

Step 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_armed

After 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

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.

One of the useful things you can use on your laptop is touchpads. They help users in achieving tasks through the gestures and multi-finger tap or touch support it brings in the scope for various shortcuts. However, not all times touchpad brings productivity as it can also encounter some issue every now and then. One of these issues has been reported on a couple of Lenovo laptops that use touchpad drivers from the Alps Pointing Device. According to the reports, an error saying, “Set user settings to driver failed” when they use the touchpad. This type of error on the touchpad usually occurs when a computer boots up and it could be caused by a faulty update on the Alps pointing device driver which is being installed in the background. To fix this error on the touchpad, you could try to disable the Alps pointing device entry from the MSConfig or you could try to get the latest version of the driver or uninstall the driver altogether. Before you proceed with the troubleshooting tips given below, make sure that you create a System Restore point first. Once you have that covered, proceed to the following options.

Option 1 – Try disabling the entry of the Alps pointing device from MSConfig

This first given option was able to fix the problem for many users so to get started, follow these steps:

• Next, go to the Services tab and look for the Alps pointing device entry from the list that appears, and uncheck it.
• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer and see if the error in the touchpad is now fixed.

Option 2 – Try to download and install the latest version of the driver

The next option you can check out to fix the error is to download and install the latest version of the driver from the official website of Lenovo support. Note that an updated version of the touchpad driver will most likely get rid of the error. However, you have to make sure that the version you’re going to get is compatible with your existing Windows version.

Option 3 – Try to uninstall the Alps Pointing device driver

If the first two given options didn’t work, you can try uninstalling the Alps Pointing-device driver instead. You can do this under the Mice and other pointing devices section. After you uninstall the driver, restart your computer and delete the driver’s leftover folder inside this location in File Explorer (C:/Program Files). Once you’re done, restart your computer and check if the error is now gone. Keep in mind that after you’ve uninstalled the driver, any extra configuration features that Lenovo drivers offered before the uninstallation will no longer be available.

Finally, some good news for Blizzard entertainment after tons of bad stuff happening around it regarding lawsuits and people layoffs. Diablo 2 has become the most-watched game on Twitch after its official release and sold copies are on a satisfactory level. For people not familiar with recent events, the state of California has sued Blizzard for various things including discrimination and offensive behavior. Later Blizzard executives were caught shredding some evidence and things just started to go to worse from there. After much drama, many people believed that this is the end for Blizzard entertainment and that they would not be able to recover from this since the community has sided with California and Blizzard has received a large punch as many subscribed WOW players have left the game. Things are not so grim as they were looking as their Diablo 2 remake has made moderate success despite being released in these troubling times and there are rumors of Overwatch 2 planned release date as of the first quarter of 2022.

Apple introduced the Live Photo feature way with iPhone 6S in their iOS9. Live Photo idea was that each time you take a photo, your phone will capture a few seconds of video along with sound and all of that is sent when you share your photo. This of course can sometimes be really bad when some not wanted audio gets recorded in the background.

Since the feature was introduced it has been set as the default option when taking pictures so each time you snap one you just capture a small amount of video and audio along. Good thing is that this feature can be turned off and the even better news is that you can edit your old photos to remove back video and audio.

How to share only photo

You can keep your Live Photos but share only a single still typical photo if you wish. Go to the photos app on your phone and select the photo you wish to share. Press the Share button on the bottom left part of the screen and once the Share menu appears tap on the Live button in the upper left corner of the selected photo. The button should turn grey and become slashed and now you can share only still photo. This is only temporary for this one specific share so next time you want to do this you will have to go through the process again.

How to disable Live Photo

If you are not happy with the previous solution and really do not want to turn off the Live feature each time you want to share a photo or you just simply do not want the feature at all there is way to turn if off for good. Take note that you can temporarily not use this feature just by opening the camera, switching to photo mode, and then tapping on the Live photo button on the toolbar that looks like three circles one inside another. This will temporarily turn the Live Photo feature for this session but next time when you open the camera by default it will be turned on again. This is a good approach if you want the feature but sometimes you just want not to use it.

In order to turn it off completely go to the settings of your phone and go to Camera and then preserve settings. inside the preserve setting turn the switch Live Photo to ON position, now go-to camera and again click on the live photo button to turn it off but this time setting will be saved and next time you open the camera it will not be ON.

Editing old Live Photos

As stated before you can edit your old pictures in order to make them stills. You can edit them to remove audio only but keep the video part, or you can completely remove everything and convert them into typical still images.

In order to only remove audio from your Live Photos go to pictures and select one that you wish to change, click on edit, and inside edit tap on the Live Photo icon (three circles). Next tap on the audio icon located in the top left corner of your screen and it will change into the mute icon. Click on done and you are finished.

To completely remove the Live photo go to Photos, select picture, click on edit and select the live photo button again. This time tap and hold the Live button next to the sound until it turns gray with a strike through it. Click on done and you are finished.

This post will guide you in fixing the error 0x80070103 when installing Windows Update. According to users who encountered this problem, Windows Update (WU) fails to install several different updates. This kind of Windows Update error is can mostly be seen in the Windows Update screen inside the update reports although it is also known to occur when a user attempts to install a peripheral driver – only if the Windows Update offers to update the driver through a prompt and when you click Yes. There are several possible causes for this error, it could be that Windows Update is trying to install a particular driver for the second time already which happens when it gets confused by an additional piece of identical hardware like the graphics adapter. Aside from that, the Windows Update might have already installed the driver which is known to occur with unsuitable versions of the already installed driver. In addition, the error could also be due to a third-party program interference like a security program or a utility program that is using the same driver and conflicts with the Windows Update. Here are some suggestions that might help in fixing the Windows Update error 0x80070103.

Option 1 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Option 2 – Try installing the failing driver without using Windows Update

If installing the updates in a clean boot state didn’t help, you can try a manual approach to yield much better results using the Device Manager or by downloading the driver from the manufacturer’s website manually.

• Tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.

Note: You also have the option to go directly to the website of your device driver manufacturer and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 3 – Try to run the Windows Update Troubleshooter

You might also want to run the built-in Windows Update Troubleshooter in Windows that could help you in resolving the Windows Update error 0x80070103. All you have to do is go to Settings > Update& security > Troubleshoot > Windows Update. From there, click on the Run the troubleshooter button and follow the next one-screen instructions that appear. After that, restart your computer and check if the error is now fixed or not by trying to install the update once again.

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.
