If you have just installed the latest Cumulative Update on your Windows 10 computer and you find that since then, the Windows 10 Start Search is not displaying any results when you try to use it to search for something in your computer, then this post might help as it will give you some suggestions to fix the problem. This problem might be caused by some bugs brought in by the new cumulative update you’ve installed. It is also possible that Cortana is having some issues or that the Windows Search service hasn’t been initialized. Whatever the cause is, here are some suggestions you need to follow to fix this issue. You can try running the Search and Indexing troubleshooter or configure the

1. Run Search and Indexing Troubleshooter
2. Configure the Windows Firewall
3. Reinstall Cortana.

Option 1 – Try to run the Search and Indexing troubleshooter

The first thing you can do is to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for Cortana are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.

Option 2 – Restart Cortana’s process in the Task Manager

Restarting Cortana’s process in the Task Manager could also help you resolve the problem. Refer to the steps given below to do so.

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

• Tap the Win + I keys to open Windows Settings.
• Next, select Devices from the menu and click on Bluetooth.
• After that, make sure that the toggle switch for Bluetooth is turned on.
• Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
• Then go back to the Bluetooth section and click on Bluetooth or other devices.
• From there, click on Add Bluetooth and select Surface Dial.
• Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.

BubbleDock is a software developed by Nosibay. It installs a customizable dock at the top of your screen.

It adds registry entities to allow it to start automatically each time your system is rebooted, as well as installing an update checker that will automatically update the software when an update is available. The software also adds various scheduled tasks to start the application at different times, this ensures that once the application is closed, it is re-launched at a later time, making it very hard to keep the software closed permanently.

While the software is running, it will generate ad links in your browser, display sponsored ads, and collect personal information and deliver it back to it’s ad network. While using this software you may see additional ads, banners, links, pop-up ads, and various other sponsored content while browsing the internet.

About Potentially Unwanted Applications

Have you ever found out an unwanted program running on your computer system and wondered exactly how the heck it got there? A PUA / PUP (potentially unwanted application / potentially unwanted program) is actually a piece of software that comes bundled with freeware and you consent to install it on your computer. These are programs you certainly don’t want on your computer since it does not provide any beneficial service. From a technical standpoint, a PUP isn’t “true” malware. An interesting difference between PUP and malware is distribution. Malware is commonly dropped via vulnerability exploitation whereas PUP gets installed with the consent of the user, who purposefully or unwittingly authorizes the PUP installation on their PC. Although a PUP is not malware by definition, it can still be harmful software and put your computer at risk exactly the same way a computer virus does.

Exactly how do PUPs look like?

PUPs come in many forms; however, most of them are adware, which usually displays irritating adverts and advertising banners on internet pages that you’re surfing. PUPs which come as browser add-ons and toolbars are widely recognizable. These toolbars alter your homepage and your default search engine in the installed web browser, track your internet activities, modify your search results with re-directs and sponsored hyperlinks, and eventually slow down your internet browser and diminish your web browsing experience. Potentially Unwanted Programs occasionally act quite much like viruses or spyware. They will carry dialers, keyloggers, as well as other software built right into them that may monitor you or deliver your sensitive details to 3rd parties. Even if the PUPs are not basically malicious, these applications still do practically nothing good on your personal computer – they’ll take precious system resources, slow your PC, weaken your device’s security, and make your PC more susceptible to viruses.

Preventing PUPs

• Study the fine print to be sure the end-user license agreement (EULA) you are accepting is only for the program you actually intend to download. • Never accept standard, express, default, or other installation settings which are recommended. Always opt for custom installation. • Use a good anti-malware program. Try Safebytes Anti-Malware which will spot PUPs and handle them as malware by flagging them for deletion. • Avoid shareware or freeware wherever possible. Disable or get rid of toolbars and browser extensions you don’t actually need. • Don’t download software from popups, online advertising, file sharing sites, as well as other unreliable sources; look out for any pre-set, unwanted features when downloading the program. Avoid heading to blogs and websites that promote pirated programs.

How To Install Safebytes Anti-Malware On An Infected Computer

Practically all malware is inherently unsafe, but certain kinds of malicious software do a lot more damage to your computer than others. Certain malware goes to great lengths to prevent you from downloading or installing anything on your personal computer, particularly antivirus applications. So what should you do if malicious software keeps you from downloading or installing Anti-Malware? There are some solutions you could try to get around with this particular obstacle.

Install in Safe Mode with Networking

Safe Mode is a unique, simplified version of Microsoft Windows where only the bare minimum services are loaded to stop malware and other troublesome applications from loading. In the event, the malicious software is set to load immediately when the PC starts, switching to this mode can prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSCONFIG and look for the “Safe Boot” options under the “Boot” tab. After you restart the PC into Safe Mode with Networking, you may download, install, as well as update the anti-malware program from there. Now, you can run the anti-virus scan to remove computer viruses and malware without interference from another application.

Switch to some other internet browser

Web-based malware could be environment-specific, aiming for a particular internet browser or attacking specific versions of the web browser. If you’re not able to download the security software program using Internet Explorer, this means the virus may be targeting IE’s vulnerabilities. Here, you must switch over to a different browser like Firefox or Chrome to download Safebytes Anti-malware software.

Create a portable USB antivirus for removing viruses

Here’s yet another solution which is creating a portable USB antivirus software that can scan your computer for malware without needing installation. Abide by these steps to run the anti-virus on the affected computer. 1) Use another virus-free computer to download Safebytes Anti-Malware. 2) Plug the Flash drive into the clean computer. 3) Double-click the Setup icon of the antivirus software to run the Installation Wizard. 4) When asked, select the location of the USB drive as the place where you would like to put the software files. Follow the activation instructions. 5) Now, transfer the USB drive to the infected PC. 6) Double-click the antivirus program EXE file on the flash drive. 7) Hit the “Scan Now” button to start the virus scan.

Technical Details and Manual Removal (Advanced Users)

If you wish to manually remove BubbleDock without the use of an automated tool, it may be possible to do so by removing the program from the Windows Add/Remove Programs menu, or in cases of browser extensions, going to the browsers AddOn/Extension manager and removing it. You will likely also want to reset your browser. To ensure the complete removal, manually check your hard drive and registry for all of the following and remove or reset the values accordingly. Please note that this is for advanced users only and may be difficult, with incorrect file removal causing additional PC errors. In addition, some malware is capable of replicating or preventing deletion. Doing this in Safe Mode is advised.

The following files, folders, and registry entries are created or modified by BubbleDock

Error Code 0xd0000272 – What is it?

Error code 0xd0000272 occurs when Windows users are unable to activate their operating system. This usually occurs due to activation servers being busy or unavailable and affects Windows 8, Windows 8.1, and Windows 10 users. Common symptoms of the error code include the following:

• Inability to activate Windows operating system
• Message box with error code 0xd0000272

Solution

Error Causes

Windows users affected by error code 0xd0000272 usually receive a message stating that the “activation server is busy or unavailable”. Some users report the error is resolved on its own after a few hours, while others experience activation issues that resolve only after manual repair methods are implemented.

Further Information and Manual Repair

To improve your chances of resolving issues related to Windows activation error codes, use manual repair methods and procedures. These are often successful as they address the issues causing the error codes to occur, whether there be missing or corrupted system files, network connectivity issues, or invalid product keys.

Error code 0xd0000272 may be resolved by simply waiting until later – a few hours at most – to reattempt activation. If, however, the activation process fails, proceed with the methods suggested below or contact a Windows repair technician.

1. Method One: Verify Internet Connection to Activate Windows

Are network connectivity issues preventing your machine from activating Windows? Check for this issue by verifying whether or not you are connected. Once you’ve been able to check your connection via your Internet settings and troubleshoot your network where necessary, proceed to the Product Activation Wizard.

The Product Activation Wizard will check if you have permission or authorized access to the version of Windows you are attempting to activate. This process usually involves the use of a product key. Once you enter the 25-character code – in the correct order, of course – proceed by selecting the activation option.

If the process is successful, you will be able to complete the activation and access all the features of the Windows edition you have activated. You will also notice the absence of the error code 0xd0000272 message. In cases where this manual repair method is unable to successfully resolve the issue, however, move to the next manual repair procedure on this list.

2. Method Two: Run Windows Update Troubleshooter

Another tool available to Windows users is the Windows Update Troubleshooter. You may access the Windows Update Troubleshooter offered on Windows 8 since it does not require an internet connection and runs most of the functions required. To do so, follow the steps below.

• Step one: Swipe to the right of the screen and click Search
• Step two: Type Troubleshooting
• Step three: Click Settings then select Troubleshooting
• Step four: Under System & Security, click Fix Problems with Windows Update
• Step five: Select Next

You can also visit Microsoft’s website to access a more comprehensive Windows Update Troubleshoot tool. Download the troubleshooter and run it to fix problems related to Windows Update. Afterward, restart your computer then check the Product Activation Wizard to verify whether or not you can activate Windows 8 or 8.1.  If the problem persists, however, and error code 0xd0000272 reoccurs, proceed to the third manual repair method.

3. Method Three: Disable Proxy Settings

Your computer’s proxy settings may in some cases interfere with the activation process, resulting in issues like error code 0xd0000272. To fix this problem, first, disable your proxy setting then reattempt the activation process using the Product Activation Wizard.

• Step one: Press Win + C keyboard combination
• Step two: Select Settings
• Step three: Click Change PC Settings
• Step four: Select Network, then Proxy
• Step six: Switch proxy server settings to Off

Open the Product Activation Wizard once you’ve disabled the proxy settings. Complete the activation process based on the instructions provided. If you are successful, you will no longer be bothered by error code 0xd0000272 as the symptoms of the error code will not occur.

If, however, this manual repair method fails to resolve the error code, you may need to consider other alternatives. These may include the use of a powerful automated tool. You can also consider getting help from a Windows repair technician as such professionals are able to assess your computer and provide solutions as needed.

As you know, Windows 10 has a complicated mechanism for Activation which helps in the verification of a genuine copy of Windows 10. However, there are times when you might encounter some errors during the activation process. One of these errors is the error code 0xc000f074. This kind of error could be due to the Key Management Service or KMS which is unreachable by the client computer or if the key used in the SLSetAuthenticationData function call is incorrect. This kind of error mostly affects surfaces on computers that are upgraded from either Windows 7 or Windows 8.1 to Windows 10. In such cases, you may encounter any of the following error messages:

“Windows is unable to reach your company’s activation service. Please connect to your corporate network. If you are connected and continue to see the error, contact your system administrator. You can also click on the error detail to find the exact error. Error code: 0xC004F074.” “Activating Windows(R), (Key hash)… Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.” “Error 0xC004F074, SL_E_AUTHN_MISMATCHED_KEY, The Software Licensing Service reported that the key is mismatched.”

To fix the Windows 10 Activation error 0xC004F078, you have to use the correct key for your type of Windows copy or use Command Prompt to reinstall the key or you could also try running the Activation troubleshooter.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation error code 0xc000f074 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try to use the correct key for the type of Windows version you have

If the Windows Activation troubleshooter wasn’t able to resolve the error, then you can try using the correct key for your type of Windows version. All you have to do so is check the type of your Windows copy if it’s OEM, retail, or volume. And make sure that you have the correct, valid product key for your operating system.

Option 3 – Try to use Command Prompt to reinstall the key

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select “Run as administrator”.
• After that, execute this command to uninstall the existing key: vbs /upk
• Next, you need to install the KMS product key by executing this command: vbs /ipk <The KMS Product Key>
• Once you’re done, you will see a prompt that’ll tell you whether the operation was either successful or not.
• To active, the KMS product key online, use this command: vbs /ato
• Use this command to activate the key using the telephone: exe 4
• After you’ve activated the KMS product key, restart the Software Protection Service. You can also verify the Activation Status to check if your fix was successful or not.

Option 4 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to upgrade your computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation error code 0xc000f074 a lot easier and faster.

If you are trying to install or upgrade your Windows 10 computer but suddenly encountered an error message saying, “Windows Could not configure one or more system components”, read on as this post will show you how you can fix the problem. You are not alone in experiencing this problem as other users also reported having the same scenario. Some of them reported getting the following error message:

“Windows could not configure one or more system components. To install Windows restart the computer with error code 0xc1900101-0x30018.”

When you check on the Windows 10 rollback log, you will see a part with the “iisetup.exe” that’s related to the abort. Usually, the upgrade process completes over 50% and gets stuck and then rolls back later on and generates the error logs. This kind of error, in most cases, appears during the upgrade of Windows 10 and is related to the Internet Information Services or IIS in Windows 10. For some unknown reason, it restricts the installation or the upgrade which causes the error to appear. To fix the “Windows could not configure one or more system components” error, you can try to remove the IIS from the Windows Features or rename the “inetsrv” folder. You could also move all the folders related to IIS to another drive. For more details, refer to the options provided below.

Option 1 – Try to remove the IIS from Windows Features

The IIS is installed from the Windows Features and you can find it at Control Panel > Programs. From there, uncheck the checkbox for the Internet Information Services. Once done, click on the OK button to save the changes. Note that this process will get rid of all the related programs, services, and folders from Windows 10. So if you want to, you can just install them later on or use an offline installer from the official site of Microsoft.

Option 2 – Try renaming the inetsrv folder

The next option you can check out to resolve the problem is to rename the “inetsrv” folder. If you have uninstalled IIS from the Windows Features, this should remove the folders as well, however, it didn’t remove the folder then you have to delete the folders that are related to the IIS by following these steps:

• First, you have to boot into the Advanced Recovery Mode and from there, open Command Prompt.
• Next, execute this command to rename the folder from this location, C:Windowssystem32inetsrv: rename C:/Windows/system32/inetsrv/inetsrv.old
• Once done, boot into your computer normally and try to upgrade Windows 10 again, and check if the problem is fixed or not.

Option 3 – Try to move the folders related to IIS to a different drive

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, look for the Application Host Helper Service from the list of services and stop it.
• Once done, take ownership of the “WinSxS” folder and then move the *windows-iis*.*” folders to another drive. You can just search using the “*windows-iis*.*” keyword in the Start Search.
• Next, tap the Ctrl + X keys and paste the folders to another drive.
• After that, start the update process for Windows 10 again.

High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.

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.
