Turn On or Off the Recommended Troubleshooting

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”. This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.

Option 1 – Try running Command Prompt with Administrator-level permissions

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again and see if you still encounter the same error.

Option 2 – Try to remove the Write Protection from the drive

As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.

Via Diskpart utility:

• Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
• Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
• After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
• Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.

Via Registry Editor:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to the following registry key:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the DWORD named “WriteProtect” and double click on it, and then set its Value Data to “0”.
• Now restart your computer and see if the problem is now fixed or not.

Installing programs on your Windows 10 computer does not go smoothly as you could encounter some issues along the way that could prevent you from successfully installing the program. One of the common errors you can encounter during the installation of programs is Error 2753. There are times when the packages are corrupted or those packages are not working properly or it wasn’t able to create files and paths. When you encounter this kind of error, you will get the following error message:

“Error 2753, The File is not marked for installation.”

Note that this kind of error is not bound to only some specific files but it can also happen with any file, be it an executable file or an MSI file. To fix this error, here are some possible solutions that you could try.

Option 1 – Fresh download the setup file

The first thing you can do is to fresh download the setup file from the official homepage and then place it in a different location. Just make sure that you download the correct setup file that’s compatible with your operating system. Then restart your computer and sign in as administrator. After that, right-click on the setup file and select the Run as administrator to proceed with the installation.

Option 2 – Try removing all the previous versions of the software

If there is a previous version of the program that’s still installed on your computer, you need to uninstall that program since it might be the reason why you’re getting Error 2753.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the previous version of the program you are trying to install, select it and then click on Uninstall to remove it.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 3 – Run the setup file as administrator

The setup file may need more permission in order to execute properly and so you need to run it as an administrator. To do so, you need to give it more privileges for it to work as intended by its developer.

• Right-click on the setup file and select the Run as administrator option.
• Afterward, a User Account Control or UAC prompt will appear and from there, click on Yes and then check if the file runs or not.

Note: If the setup file does not run, you may have to take ownership of the folder where the setup file is located. To take ownership of the folder, refer to these steps:

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 4 – Try running the setup file in Compatibility Mode

You may be getting Error 2753 if the setup file is not intended to run on the Windows 10 version you are using which is why you have to run it in Compatibility Mode. This will allow the setup file to think that it is running in a compatible environment as it is intended to.

Option 5 – Try to re-register the vbscript.dll file

You may have to re-register the vbscript.dll file using the regsvr32.exe before you can successfully install the program and fix Error 2753. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type exe vbscript.dll in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

The quickest way to control and manage the volume of your Windows 10 PC is using the Volume control icon in the system tray. However, you might encounter issues in using it especially if you recently updated your PC. After the update, if it no longer responds to mouse clicks, be it a right-click or left-click, read on as this post will show you what you can do to remedy that issue. If you think that you’re the only one who has experienced this problem, you are mistaken as several users also reported that the volume icon does highlight and shows the volume level if you hover the cursor over it but it does not really do anything at all. This is definitely the quickest way to change the audio output in Windows 10 especially when you have to change from speakers to your earphone and whatnot. If you are one of the users whose Windows 10 Taskbar Volume Control icon has stopped working and every time you click on the icon and nothing happens and you’re still not able to adjust the volume of your Windows 10 computer, read on as this post will show you what you can do to fix that problem. Although the audio is working just fine, you will still not be able to adjust the volume from its control icon. The problem is most likely related to the UI interaction. There are times when icons in the taskbar also experience the same issue where you can hover your mouse over them but nothing happens when you click on them. As mentioned, the issue with the volume icon does not seem to affect the actual audio of the computer. Double-check to confirm and if it turns out that the audio is indeed working fine, you can use the hardware of your keyboard to manage and control the volume, however, the software just won’t work. This issue is really inconvenient especially for users who connect their laptops to a bigger display. To fix this issue, here are some suggestions you need to check out.

Option 1 – Try to restart the Windows Explorer

This option may sound silly but it has actually worked in fixing the issue for some users. So if anything gets stuck on the taskbar or system tray, the best way to revive them is by restarting Windows Explorer.

• Right-click on the taskbar and then select the Task Manager.
• Next, look for Windows Explorer under the Processes tab.
• Then right-click and select restart.
• After that, wait for the restart process to be completed and for the user interface to refresh. Note that you will notice the Taskbar disappearing and reappearing again. It will reload the entire user interface and allows you to access the volume icon. It should work this time.

Option 2 – Restart the Audio services

Restarting the audio services in your computer can also help you fix the volume control issue and to do that, refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Type in “services.msc” in the field and hit Enter to open Services.
• From there, look for Windows Audio and then right-click on it and go to Properties.
• After that, you have to make sure that the Startup Type is set to Automatic.
• Then click on the Stop button. Once it has stopped, start it again.
• Now restart your computer and see if you can now access the volume icon on the taskbar.

Option 3 – Try to update or roll back the Audio driver

If the glitch in your audio has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 4 – Try running the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the volume control issue on your PC. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

Error Code 48 – What is it?

Error Code 48 is a device driver error code that users can encounter on any Windows 2000 operating system and later versions.

It occurs when the connected peripheral device cannot be run as the Windows operating system’s driver required to install the programs for peripheral devices has either been corrupted or is incompatible with the system.

It prompts the user with the following message on the screen:

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

Solution

Error Causes

Like most other Windows error codes, error code 48 is triggered by the following factors.

• Corrupted system registry files
• Presence of viruses in the device
• The device driver is out-of-date

If this error code is not rectified, it could give birth to other driver device errors such as error code 52.

Further Information and Manual Repair

Method 1 – Run a complete scan for malware and spyware

Identifying and removing the viruses in the system registry and in the connected devices is the easiest method to fix the corrupted registry files.

Viruses such as spyware and malware infect the registry entries and eat up the files that lead to incomplete or missing data. This creates problems for installing external devices as the driver required to install them is not complete.

Method 2 – Use System Restore

You can also use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows to restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via the last saved system checkpoint, you can obtain undamaged Windows system registry files that can help resolve the error code.

Method 3 – Manually uninstall and reinstall the device driver

Since Error Code 48 is due to a missing or an out-of-date device driver, uninstalling and then reinstalling the device driver can help solve the error.

You can do this by firstly logging in as Administrator and opening Device Manager. Select the device that is causing the problem and double click it; make sure that the peripheral is connected properly to the PC.

Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’. Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 4 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick; however, it may be time-consuming especially when you would have to resort to your hardware user manual. Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer. DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

The issue with the abrupt system reboots to force Windows 10 updates on a computer has been lessened with Active Hours. This feature keeps a record of the hours during which a system remains active and prevents the installation of updates during such hours. For example, when a system restart is needed to complete the installation of an update, Active Hours delays the update and allows you to finish what you’re doing on your computer. Thus, if you haven’t heard of this feature, then now is the time you do, read this post to configure and use Active Hours in your Windows 10 computer. There are three ways you can configure Active Hours. The first one is for general users, whereas the rest of the two methods are for users who knows their way about the Windows Registry and Group Policy. To get started, refer to every given option below.

Option 1 – Configure Active Hours via Windows 10 Settings

• Go to Settings > Update & Security. From there, click on the “Change active hours” option under the Windows Update section.
• Next, you can select a time (“Start time” and “End time”) during which the restart can occur.
• After that, click on the Save button and exit.

Note: Keep in mind that the values you’ve entered indicate the hours during which your system is in use, namely, ACTIVE. It is important for your active hour’s interval period and it can be anything between 1 and 18 hours since you can’t go beyond 18 hours. In addition, there is no option to configure different active hours on different days and you can’t specify different active hours for weekends and weekdays as well. On the other hand, Windows 10 also offer users an option to override Active Hours. All you have to do is go to Settings > Update & Security > Windows Update > Restart Options. From there, you can choose a custom restart time when your computer will restart to install the updates but this is only a one-time setting.

Option 2 – Configure Active Hours via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter or click OK to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsUpdateUXSettings
• In the given registry path, you can choose to change “ActiveHoursStart” and “ActiveHoursEnd”.

Note: There are no extra settings available in the Registry Editor but you can change the remote computer’s Active hours settings using the Registry Editor.

Option 3 – Configure Active Hours via Group Policy

Note that this option is available for the Windows 10 Pro and Educational or Enterprise versions. It is mostly used by computers in Business or through remote access. To get started, follow these steps:

• Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and tap Enter or click OK to open the Group Policy Editor.
• Next, navigate to this group policy setting: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Updates.
• From there, look for a policy labeled “Turn off auto-restart for updates during active hours” and double click on it. This will open a new window.
• Click on the Enabled radio button to enable Active Hours. You also have the option to choose active hours just like in the first given option above. It works just fine except when the following policies don’t override:
  • No Auto-restart with logged-on users for scheduled automatic updates installations.
  • Always automatically restart at the scheduled time.

• Since Group Policy allows you to reduce the range of active hours, you can configure it if you want it to be less than 18 hours. Just find the policy setting labeled “Specify Active hours range for auto -restarts. The minimum is 8 hours”.
• After you set the Active Hours, click the Apply and OK buttons to save the changes made.

What is Error 0xe0434f4d?

Error 0xe0434f4d displays when a remote computer runs an instance of the SQL Server 2005 but it fails to initialize. When the plan is started, this error displays in a status window on the SQL Server. Also, when the Update-OffilineAddressBook cmdlet is started in Microsoft Exchange Server, this error can occur.

Solution

Error Causes

Error 0xe0434f4d can occur for possibly two main reasons. The first one is when the System Attendant Service is not properly running, and the second when you don’t have the permission to run the update. Other causes are when the .NET Framework 2.0 security does not allow sqlplanlaunch access to run from a shared network. Another cause is when the Offline Address Book (OAB) is not found in the Configuration Domain Controller server that the server of OAB generation uses.

Further Information and Manual Repair

In case you didn’t know, the Offline Address Book generation server is a mailbox server, and in order to resolve error 0xe0434f4d, you will have to replicate the OAB object to the Configuration Domain Controller server. In order to do so, follow steps:

• Go to start and click on All Programs, then go and click on Microsoft Exchange Server 2010. Click on Exchange Management Console
• In Exchange Management Console, go to Server Configuration and click on Mailbox
• In the details, go to mailbox server that generates Offline Address Book and right-click it, then go to Properties
• In the Properties, click on System Setting and locate the domain controller name in the box that reads Domain controller servers being used by Exchange

Make sure the OAB object is reproduced in the Configuration Domain Controller Server. Follow these steps to do that:

• Go to Start and click on Run. Type Adsiedit.msc in Open box and press Enter. Right-click on ADSI Edit and click on Connect to
• Locate a list reading Select a well-known naming context, and from there select Default naming context. In a Select or type a domain or server window, type FQDN (fully qualified domain name) of the Configuration Domain Controller server which was determined in step 1, and click OK
• Expand Configuration [dc.domain.com], expand CN=Configuration, DC=domain, DC=com, expand CN=Services, expand CN=First Organization, and expand CN=Address Lists Container
• Click on CN=Offline Address Lists and make sure the OAB object is listed on the details pane

When the OAB generation server receives this, then it will connect to the Configuration Domain Controller server and will locate the OAB object. If the OAB generation server is unable to find the OAB object, then the error will return on the cmdlet. On SQL Server, you should change the .NET permissions to allow sqlplanlaunch application access to run from shared administration. For that, follow these steps:

• On ArchiveIQ Server, open System from the Control Panel and note down the computer name
• On SQL Server, log in as administrator and open the command prompt
• On the command prompt type, ‘C:windowsmicrosoft.netframeworkv2.0.50727caspol.ece –m –ag l – url file:\[Archive IQServer Computer Name]AlQRemote$*FullTrust and Press Enter. Type yes and press Enter again to confirm the permission changes.

Blue Yeti has gained popularity among streamers and users that want a high-quality mic for their setup. Without going into details of the hardware itself I will say it is a pretty good mic.
