A Quick Method To Fix Error Code 0x80070002

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 most common hardware issues with any PC usually has something to do with the hard drive so if your hard drive experiences some errors, you could end up losing a lot of important information that’s stored in your computer. This is why Windows provided users with the CHKDSK utility which helps in looking for bad sectors on the drive. However, there are times when the CHKDSK utility could also face issues like the following error:

“Failed to transfer logged messages to the log event with status 50.”

According to security experts, this error is most likely due to the hard drive or RAM being in a “Read-only” state. It could also be due to some physical issues with the hard drive. On the other hand, it could be that the system is prevented from creating logs by some drive, service, or malware. To fix this error, you have to check if the hard disk is writable. You could also try to run the CHKDSK utility in Safe Mode or you could also check the physical status of your hard disk or external drive.

Option 1 – Check if the hard disk is writable

Although the CHKDSK utility checks for bad sectors in the hard drive, it also has to create logs of the result. And as states in the error message, the CHKDSK utility is not able to log the logged messages. This kind of error occurs when the log can’t be written to an installation disk. You can find the log in this location, “C:WindowsSystem32LogfilesSrtSrtTrail.txt”. Now you have to check if the drive writable by following these steps:

• Log in as administrator and right-click on the system drive.
• Select Properties and then go to the Security tab. Here, check if you are allowed to modify the drive. If not, click on Edit (as an administrator).
• Now edit the permissions for the SYSTEM and Administrators group. Note that these are the only default settings for these two groups or usernames.
• Then click on the Apply button save the changes made and exit.

Option 2 – Run the CHKDSK utility in Safe Mode

You could also try to run the CHKDSK utility in Safe Mode as this might solve the error.

• Boot your computer in Safe Mode.
• Next, open Command Prompt with admin privileges.
• Then type and enter this command to execute it: chkdsk c: /f /r
• Wait until the process is completed and boot your computer normally and then run the CHKDSK utility again and check if the “Failed to transfer logged messages to the log event with status 50” error is now fixed.

Option 3 – Try to check the hard disk or external drive physically

If the first two options didn’t work, you might want to check the physical status of your hard disk or external drive as the problem could root from there. You can try to tighten the wires that connect the hard disk to the motherboard. However, if it doesn’t help, you should seek out assistance from a hardware technician.

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.

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

What is the Registry Error Code 19?

Code 19 is a Windows PC error code that indicates a damaged or corrupt registry. This code usually appears when trying to start a connected device, the DVD/ CD ROM drive. Code 19 is a type of Device Manager Error code. When you experience Code 19, the error message is displayed on your Windows screen in either of the following formats:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. To fix this problem you should uninstall and then reinstall the hardware device. (Code 19)"

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. To fix this problem you can first try running a Troubleshooting Wizard. If that does not work, you should uninstall and then reinstall the hardware device. (Code 19)"

You might encounter other error messages such as error code 42.

Error Causes

Typically the underlying cause of this error code is problems in the registry. The error should be fixed timely without any delays before the damage sets in. Registry issues are critical PC errors. If not resolved it can lead to system freeze, crash, and failure. You are most likely to lose all your important data.

Further Information and Manual Repair

If you have come across this error on your computer, you don’t need to panic. Though this is a serious issue the good news is that it is easy to resolve. You don’t have to be a computer programmer, technically sound or hire a technician to fix the error on your system. Here are a couple of ways to work your way out of this problem:

1. Uninstall and then Reinstall the  DVD/CD ROM Drive

For this here’s what you need to do: simply click on the start menu, and type Device Manager in the search box, and press enter. When the device manager window opens locate the DVD/CD ROM drives. Click on the + sign to expand it. Now right click on the DVD drive click uninstall. After doing this, restart your PC. On the restart, Windows should automatically detect and reinstall the DVD driver. Once the driver installation is complete now see if the DVD drive works. If the error still appears, then you need to repair the registry by deleting the corrupt registry entries. You can download drivers automatically by using a tool such as Restoro.

2. Trouble Shooting Method to Delete the Corrupt Registry Entries

To remove the corrupt registry entries, go to Start and select Run. Type ‘Regedit and press enter to open the registry editor windows. To continue you may be asked to enter the administrator password, insert it to proceed. Now the registry window will be displayed. Here locate the registry key HKEY_LOCAL_MACHINE, then navigate to the following sub registry key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318} Here you will see the upper filters registry entry in the right pane. Right-click on the upper filter and select delete. You will be prompted for the confirmation for deletion. Click on the yes tab to confirm. Exit the editor and restart your computer. If you are not technically sound, this may be a little confusing for you, and besides it does not guarantee to resolve all the registry issues on your PC so chances are that Code 19 error may reappear in a short time. To resolve registry issues for the longest time and ensure that errors like Code 19 don’t pop up every now and then, you need to perform proper and in-depth registry cleaning. For this, it is advisable to download Restoro.

There are instances when instead of fixing problems the Windows Update brings you problems on your Windows 10 computer. You might even see some pending Windows Updates which for some reason, refuse to install no matter what you do. The good thing is you won’t have to deal with those failed and pending updates that are incompletely downloaded to your PC as you can actually delete them. Follow the instructions prepared below to delete the failed and pending Windows Updates.

Step 1: The first thing you have to do is delete all the contents in the Temporary folder

• Tap the Win + R keys to open the Run dialog box.
• Next, type in “%temp%” in the field and hit Enter or click OK to open the Temporary folder.
• From there, select all the folders and files within the Temporary folder and then delete them all.

Note: %temp% is one of the many environment variables in Windows that could open the designated folder by Windows as the Temporary folder which is usually located at C:\Users[username]AppDataLocalTemp.

Step 2: Next, remove the pending.xml file

• Go to the C:\Windows WinSxS folder.
• Once you’ve opened the folder, look for a file named “pending.xml” file and right-click on it and you can either rename it or delete it.
• After that, the Windows Update should delete the pending tasks and build a fresh new update.

Step 3: Delete all the contents of the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, got to the C:\Windows\Software\Distribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Step 4: Try resetting the catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.
