Remove ChatZum from Windows

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.

Error Code 0x80070003, 0x20007 - What is it?

Update Error 0x80070003, 0x20007 One of the most common errors encountered by users who updated to Windows 10 is the Error Code 0x80070003-0x20007.

One of the most useful and powerful built-in utility in Windows 10 is the DISM tool. This tool can be used with the Command Prompt command line as well as for other purposes. However, it is not without flaws and there are times when you may encounter some issues while using it. One of the problems you can get while using the DISM tool is the following error:

“The scratch directory size might be insufficient to perform this operation”

This kind of error in DISM occurs when the DISM command is executed from the Windows Recovery Environment due to the limited size permissions of a delivery where the operating is being performed. To fix this DISM error, you need to follow the instructions laid out below. Step 1: First, tap the Win + R keys to open the Run utility and then type “cmd” in the field and tap Enter to open Command Prompt. Step 2: Next, you have to specify a scratch directory that contains the Windows folder and to do that, you can either use the DIR command or the BCEDIT command. So in the elevated command prompt type and enter “dir” or “bcedit”. Step 3: After that, you will see a list of folders inside the C: partition. Now you have to create a folder named “scratch” inside the partition. To do so, execute the following command:

mkdir C:Scratch

Note: The command you just entered will create a directory inside the root of the C: partition named Scratch. Step 4: Now that you’ve created the Scratch folder, note that each time you run any of the DISM commands, you have to enter the following code snippet in them:

/ScratchDir:C:Scratch

 Note: For instance, if you are using the DISM tool to repair the offline Windows image, instead of executing the “Dism /Online /Cleanup-Image /RestoreHealth” command, you now have to execute the “DISM /Image:C: /ScratchDir:C: Scratch /Cleanup-Image /Restorehealth” command. And if you want to remove a selected installed update package, you can use the “DISM /image:C: /ScratchDir:C:Scratch /Remove-Package /PackageName:Package_for_RollupFix~31bf3856ad364e75~amd64~~16299.196.4.9” command. Keep in mind that the mentioned package is only an example. And lastly, you also have to replace the drive letter in the new code snippet when you execute the commands given above.

A lot of users prefer to use Microsoft OneDrive when it comes down to cloud storage as it does not only come with the seal of approval from Microsoft but it’s also primarily good and better compared to other cloud storage services. However, that doesn’t mean that OneDrive isn’t without any issues. For one, you might encounter an issue where the OneDrive thumbnails do not show in File Explorer in Windows 10. If you are currently experiencing this problem, read on as this post will help you fix it. As you know, you can add OneDrive to your Windows 10 computer and have all the files locally synchronize to the cloud and so on. This means that whatever is available in the cloud will be seen on your computer. It is smooth and definitely saves you a lot of time which is why a lot of users prefer to use it. So if you suddenly not see any thumbnails in OneDrive, then that would be a problem. You are actually not the only one having this problem as there are other users who reported getting the same issue recently about the picture thumbnails that no longer show up in the OneDrive folders in the File Explorer. At the time of writing, it isn’t clear yet what the cause of the issue really is. Even so, there are still potential fixes you can check out to resolve it, and the sooner you do it, the better as this can be a major problem. To get started, refer to the instructions given below.

Option 1 – Try to disable Files on Demand

The first thing you can do to fix the problem is to disable the Files on Demand. This is what you have to do to get things under control.

• First, right-click on the OneDrive icon located in the taskbar and go-to of OneDrive.
• After that, click on More and Settings. This will open a new window where you have to click on the Settings tab and uncheck the “Files on Demand” service.
• Once done, restart your computer and check if you can now see the thumbnails in the OneDrive folder. However, if it didn’t work, then proceed to the next given option below.

Option 2 – Try to change the icon view

The next thing you can do to fix the problem is to change the icon view. It is possible that the problem might have something to do with the size of the icons than anything else. So you have to change the icon view and to do that, follow these steps:

• First, open Control Panel in Windows 10.
• Next, in the search box, type “folder” and then click on the File Explorer Options.
• From there, click on the View tab and uncheck the “Always show icons” option, and make sure that showing thumbnails is active.
• Now go back to Control Panel and type “system” in the search box. This will open a new window where you have to select the “View advanced system settings” option.
• Then under the Performance section, click on Settings and click on the option that allows you to show the thumbnails instead of icons.

Portable small Bluetooth speakers are nothing new on the market, most of the time they have given the opportunity for music listening during picnics and walks in nature and also replaced some car speaker systems. The latest star in small portable speakers in JBL Clip 4, small in size, waterproof, and with an incredible high-quality sound.

Performance and quality

Out of the box and after first look speaker looks great, it has excellent design and is very intuitive to work with. Everything is laid out logically and you can start using it right away without reading instructions.

The sound quality is surprisingly very good and clear. I must say I have not expected this clarity and power from a speaker of this size. The volume range is also incredibly good and will fill most needs even on small picnics outdoors where you can hear it loud enough. One thing to mention is that even on their loudness levels sound is still clear without distortion which, to be honest, is to be expected from someone like JBL.

Where you can take JBL Clip 4

You can take it where ever you want, Its size and clip make it perfect for beach and pool trips. Speaker is waterproof and gas IP67 rating, meaning that sand and dirt will not affect it either. Do not take this speaker to your diving adventures since that will break it but a depth around 1 meter underwater should be safe. After your trip do not forget to wash Clip 4 with clean water so all dirt, salt, and other stuff are properly cleaned for longer life of the device.

How long it will play?

JBL claims that the battery will last 10 hours of continuous play. Note that this is meant probably on the largest volume setting so when you use it on lower settings battery is lasting longer. Playing of course on low volumes will extend playback time even longer but here we come at one feature that I do not like, there is no indication of any kind how much battery is left in the speaker, the only indication is a red light when the battery is almost empty which means you could be outside at that point and did not know that low battery was there in the first place when you were packing. Some battery indication would be a great addon.

More stability for JBL Clip 4

The clip itself has been improved from the previous Clip 3 model, it is wider, it goes all the way around the casing, and feels overall better and more stable. Since the clip is now all around casing this means a wider opening can be made making it fit around stuff Clip 3 was not able to.

Conclusion

All in all, Clip 4 is an incredible speaker and one that would highly recommend, the price goes around 79 USD but it can be found even as low as 50 USD on discounts and promotions and if you manage to get one at that price it is a great buy. Sound is good, portability is great, dirt and waterproof are excellent and battery life is really good.

In an operating system, it is ideal for an administrator to have permission to access all the folders and files. However, there are times when you try to access the security settings or attempt to view the properties of a file, you could encounter an error saying, “You do not have permission to view this object’s security properties, even as an administrative user”. This kind of error may be caused by several reasons. For one, if your computer is infected with a virus or malware which might have caused some changes to the concerned folder or file. It could also occur if a program or service is using the folder or file simultaneously which explains why you’re not able to access the system. It could also be that the folder or file might have been owned by a user account that no longer exists or you might not have the permissions to view the targeted folder or file even though you’re logged in as administrator. To fix the “You do not have permission to view this object’s security properties, even as an administrative user” error, here are some options that might help.

Option 1 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that’re preventing you from accessing security settings or properties of a file and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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 you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 2 – Try booting your computer into Safe Mode and delete inactive users

Aside from the Clean Boot State, you can also reboot your computer in Safe Mode and then delete all the inactive users. There are instances when the folder was created or owned by a user account that’s either deleted or inactive now and so you need to get rid of these inactive user accounts to resolve the error.

• First, boot your computer in Safe Mode.
• Then right-click on the concerned folder or file and select Properties.
• Next, select Advanced in the Security tab and click on Add.
• A new window will appear and from there, click on “Select a principal”.
• And then type the name of the user to who you wish to give permissions in the “Enter the object name to select” box.
• Now select Check Names and this would resolve the user name.
• After that, click OK to save the settings. This will close the window and take you back to the previous one.
• Next, from the drop-down menu, change the Type to Allow and select the Full Control checkbox.
• Click OK to save the changes made and then restart your computer in a normal mode.

Option 3 – Try to take ownership of the folder or file

Another thing you can do to fix the problem is to take ownership and force the system into giving permissions to the Administrator. How? Refer to these steps:

• Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
• After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Next, type and enter this command: TAKEOWN /F <path>
• Note that the <path> is the location of the folder or file in File Explorer.
• Now type and enter this second command: ICACLS <path> /grant administrators:F
• Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 4 – Try scanning your computer using Windows Defender

As mentioned, the error when accessing the security settings or properties of a folder or file might be due to a virus or malware. It could be that it had made some modifications that prevents you from accessing security settings or properties. To eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

There are times when the WMI Repository gets corrupted which results in the Provider Load Failure. To resolve this issue, you need to repair or rebuild the WMI Repository in your Windows 10 computer. In this post, you will be guided on how exactly you can do that. In case you don’t know, the WMI which stands for Windows Management Instrumentation is a set of specifications from Microsoft to consolidate the management of devices and applications in a network. The WMI is a database that stores meta-information and definitions for WMI classes. Using only these, the conditions of the systems can be known. You can find the WMI Repository in %windir%System32WbemRepository. It provides end-users with the status of the local or remote computer system. Keep in mind that you must not use this on the Server 2012 Cluster machine. Although there are command-line tools that can fix or restore the Windows Management Instrumentation repository. However, Microsoft suggests that it’s better if you verify if there is corruption. Here are a list of errors as well as permission issues you might encounter:

• Unable to connect to root default or rootcimv2 namespaces. It fails with the error code “0x80041002” pointing to “WBEM_E_NOT_FOUND.”
• 0x80041010 WBEM_E_INVALID_CLASS
• When you open Computer Management and Right Click on Computer Management (Local) and select Properties, you get the following error: “ WMI: Not Found” or it hangs trying to connect
• Trying to use wbemtest , and it hangs
• Schemas/Objects missing
• Strange connection/operation errors (0x8007054e)

To verify if there is corruption, you can try running the following command in an elevated Command Prompt:

winmgmt /verifyrepository

 After you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.

Option 1 – Try to reset WMI Repository

• Type “command prompt” in the Start Search and right-click on Command Prompt from the search results and then select “Run as administrator”.
• After opening Command Prompt with admin privileges, type and enter this command: winmmgmt /salvagerepository

The command you entered is used when the winmmgmt command performs a consistency check. So if an inconsistency is detected, it will rebuild the repository.

• Next, execute this command to see if the WMI repository now comes back as consistent: winmgmt /verifyrepository

This command will perform a consistency check on the WMI repository.

• If it states that the WMI repository is not consistent, then you need to type and enter this command: winmgmt /resetrepository

This command is used to reset the repository to its initial state when the operating system was first installed.

Option 2 – Try to force recover the WMI Repository

The WMI Repository comes with a built-in self-recovery process so when the WMI service restarts or detects any corruption, it will automatically trigger the self-recovery procedure. This can happen in two ways:

• AutoRestore: This will use the backup images if the Volume Shadow copy or VSS backup is turned on.
• AutoRecovery: The rebuilding process will generate fresh images of the WMI repository based on the registered MOFs. The MOFs are available in the registry located at HKLMSoftwareMicrosoftWBEMCIMOM: Autorecover MOFs

Note: Autorecover MOFs is a key so double click on it to check its value. On the other hand, if the self-recovery procedure does not work, you can try to use the force-recovery process instead. How? Refer to these steps:

• First, you need to check the reg key value is empty or not under this registry path: HKLMSoftwareMicrosoftWBEMCIMOMAutorecover MOFs
• If the reg key value is empty, you have to copy-paste the reg key value from another computer. Just make sure that it’s from the System which is equivalent to the computer in question.
• Next, type and enter this command: Winmgmt /resetrepository
• After you enter the command, if you get an error that says, “WMI repository reset failed. Error code:0x8007041B. Facility: Win32”, then you have to stop all the Dependency Services on the WMI service by running the following commands:
  • net stop winmgmt /y
  • Winmgmt /resetrepository

This should fix the problem.
