NVIDIA Control Panel is not opening

There are a lot of reasons to ban or block different websites in your Windows. From wanting to limit yourself from distraction to block certain sites for sake of kids not going into them. Whatever your reason might be, keep reading in order to find out how you can block any website inside Windows for all browsers. The technique I am going to share with you is universal and not tied to Windows versions, they will work in any Windows from XP onward. Also, the technique will block desired websites on any browser, already installed or even ones that will be installed after doing the trick. And we will also be looking at applications that can help you in this task if you do not wish to do it manually.

Block websites using dedicated software

A small free application called Focal Filter which can be found here: https://www.focalfilter.com/ is a software solution for your needs. It is a pretty straightforward and easy-to-understand application and not really much can be said here about it. You simply download and install it, set your websites, and you are done, the app does rest.

Blocking manually via host file

Another method besides mentioned one using the dedicating application is to manually set site addresses inside the Windows host file. The first thing, of course, is to open the host file, run a notepad with administrator privileges, go to file open, and navigate to c:\windows\system32\drivers\etc\hosts. Once the file is opened go all the way down and add: 127.0.0.1 SITENAME For example: 127.0.0.1 www.youtube.com or 127.0.0.1 www.facebook.com This way each time user on a PC tries to access a listed website computer will reroute it to the given address which is your PC's local address and asked website will not be able to load.

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

Hello and welcome everyone. In today's article, you will learn how to lock folder and content in it. Please be aware of few things:

1. The method is shown here works, but you need to be careful and follow step by step or you will damage your files permanently,
2. If you forget your password, you can not access your files anymore
3. Your files altho protected can still show up in recent files of some applications

All of that being said, let us start with locking the local folder on the computer with the password. Go to the folder where you have files that you would like to hide and lock with a password. Enter the folder and create the new text file inside it. Skip the name for now and go inside it. Copy and paste the following code inside the file:

---

cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Are you sure u want to Lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to Unlock folder set/p "pass=>" if NOT %pass%==Your-Password-Here goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md Locker echo Locker created successfully goto End :End

Now locate this line of code in the document: if NOT %pass%==Your-Password-Here goto FAIL and replace Your-Password-Here with your password. !!! Write down somewhere your password, if you lose it you will lock the folder even for you !!! Save the file as FolderLocker.bat and double-click on it to execute it. If everything was done correctly, a new folder with the name: Locker Move files that you want to hide and protect inside that folder. Double click again on FolderLocker.bat The command prompt will appear with the question do you want to lock the folder, press Y, and press ENTER. The command prompt will close and the Locker folder will disappear. In order to unhide and access the folder, you will need to double click on FolderLocker.bat again but this time command prompt with ENTER your password will appear. Type in your chosen password and the folder is back. If you wish to hide and lock it again just double click on FolderLocker.bat again, confirm with Y and it is hidden again.

Quest 2 has been crowned as the best overall VR headset by many websites, and to be honest it is really a great piece of equipment deserving of every praise it gets. It seems that Meta feels that it can do better so the new upcoming Quest Pro is upgraded and a new line of VR sets from this company. The economic standard Quest line will not be shut down and it will still remain as an economic version of Meta's VR product line.

Quest Pro will be added as a new line of the better product line with better performance and better quality. It is the first VR headset that is packing Qualcomm Snapdragon XR3+ Gen 1 chipset, 12GB of RAM, 256GB of internal storage, and 10 high-resolution sensors. Of course, this much power and improvement come with a higher price tag, this time that price tag is $1,499.99.

The new VR headset promises industry-leading visuals with a new optical stack instead of Fresnel lenses in Meta Quest 2 with thin-layer pancake optics that fold light reducing the depth of the optical module by 40% and at the same provides clear and sharp visuals.

The headset will give display more vivid colors, richer colors, and higher contrast by incorporating local dimming and quantum dot technology. It composes of specialized backlight hardware accompanied by software algorithms that can control more than individual LED blocks independently.

The Quest Pro will also come packed with new Meta Quest Touch Pro controllers. They will feature three built-in sensors to track the controller's position completely independent of the headset which means that tracking and range of motion will be improved. These new controllers will also be sold separately at the cost of $299.99 and they can be used with Quest 2.

The headset is available for preorder and it will start shipping in late October on the Meta website

What Is 0x80004005 Outlook Error?

0x80004005 Outlook is an error that users commonly encounter while attempting to send or receive emails on Outlook.

The message that appears usually states “This message could not be sent. Try sending the message again or contact your network administrator."

The client operation failed. Error is [OX80004005- 0X0004B9-OXOO501].

What is DISM Error 1726? Every time you encounter some issues in your Windows 10 computer, especially when it comes to corrupted system files, you can always use the SFC scan and if the SFC can isn’t able to resolve the issue, there is also the DISM tool you can use which usually resolve the vast majority of system file corruption sufficiently. However, there are times when even the DISM commands experience issues as well. Such is the case with the 1726 error: “The remote procedure call failed”.

Some users reported that this DISM problem happens right before the process is supposed to end. According to experts, this error in DISM occurs due to any of the following reasons:

1. A third-party program might have interrupted the DISM operation and is the one that triggered the 1726 error: “The remote procedure call failed”.
2. The error could also pop up when there is a pending corruption repair. This usually happens when you tried to run a DISM command previously that was terminated manually or was halted because of some malfunction.
3. Lastly, the error could also occur because the process that’s responsible for the procedure is disabled or was prevented from running.

Whichever the case is, here are some suggestions that might help you in resolving the 1726 error: “The remote procedure call failed”.

Option 1 – Try updating your PC to the latest Windows build available

Since the problem is specific to certain builds in Windows 10, you need to make sure that your computer is updated before you try other troubleshooting steps. Thus, follow the steps below to update your Windows 10 PC.

• Tap the Win + R keys to open the Run dialog box.
• Then type “ms-settings:windowsupdate” in the field and hit Enter to open the Windows Update screen.
• After that, click on Check for Updates and then follow the next on-screen instructions to apply the latest Windows update.
• Once the update has been installed, restart your PC and run the DISM command again and see if the problem is fixed.

Option 2 – Try to change the Startup Type of the Remote Procedure Call service

As stated early on, the error might also be caused by a disabled Remote Procedure Call service or RPC or that it might be prevented from running for some reason. In case you don’t know, RPC is the service control manager for both COM and DCOM servers and it’s responsible for performing object variation requests, exporting resolution as well as distributing collection for the servers. And so if the server is disabled, all programs that are using COM and DCOM including the DISM commands, will not function correctly. Thus, you need to make sure that the RPC service is scheduled to enable itself on every system boot. To do so, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• Type “services.msc” in the field and hit Enter to open Services.
• From there, scroll down until you see the Remote Procedure Call (RPC) service and then right-click on it and select Properties.
• Then go to the General tab and change the drop-down menu next to Startup type to Automatic.
• After that, click the Apply button and then OK to apply the changes made.
• Restart your PC and run the DISM command once again at the next startup.

Option 3 – Try to modify the RpcSs registry key value

If the option didn’t work, you can also try enabling the RPC service using the Registry Editor. Before you proceed, make sure to create a System Restore point first and then follow the steps below afterward.

• Tap the Win + R keys to open the Run dialog box.
• Type “Regedit” in the field and hit Enter or click OK to open the Registry Editor. And if a User Account Control prompt appears, just click on Yes.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services RpcSs
• After selecting the aforementioned registry key, go to the right pane and double-click on the Start value.
• Next, change the Value data of start to 2 and click OK to save the changes made.
• Exit the Registry Editor and restart your PC and check if the 1726 error in DISM has already been resolved or not.

Option 4 – Try to disable the Windows Search service temporarily

Some users also recommended disabling the Windows Search service for the meantime as it could be the one that’s interrupting the DISM process.

• Tap the Win + R keys to open the Run dialog box.
• In the field, type “services.msc” to open the Services window again and hit Enter to open it.
• Next, scroll down over the services list and double-click on the Windows Update service.
• Afterward, go to Windows Search properties and click the General tab and then click the Stop button to stop the service from running temporarily.
• Now try running the DISM commands again and see if the problem’s fixed or not.
• Restart the Windows Search service and then restart your PC as well.

If you are having issues with your network connection and you have it configured to DHCP, then you shouldn’t have any issues in figuring your IP address out. If you want to prevent conflicts between network devices and enable their easy management, then you have to set a static IP address in your Windows 10 computer, worry not for this post will show you how it’s done. The IP addresses for computers are usually configured to the Dynamic Host Configuration Protocol or DHCP automatically by the respective router. This is really convenient since the devices instantly connect to your network and through this, you can save yourself the trouble of configuring the IP address for each new device manually. However, there’s a shortfall in the process – the computer’s IP address can change every now and then. Moreover, you might also find it a lot easier to share a printer or configure a Port forwarding when you set a static IP address. There are three ways to do it – you can set it via Control Panel or Windows Settings or using Windows PowerShell. For more details, follow the options provided below.

Option 1 – Set a static IP address via Control Panel

• Right-click on the network or Wi-Fi icon located in the Taskbar.
• Then select the “Open Network and Internet settings” option from the given list of options.
• Next, go to Wi-Fi settings and scroll down until you see the “Related Settings” section. Here, click on the “Change adapter options” link which will open a new window that will direct you to the Network Connections section of the Control Panel.
• After that, right-click on the network connection you want to set a static IP address for and then select the Properties option.
• Then select Internet Protocol Version 4 (TCP/IPv4) under the Networking tab and click the Properties button.
• Now switch the selector to the “Use the following IP address” option and make the entry for the following fields that correspond to your network setup.
  • IP address (Find it using the “ipconfig /all” command)
  • Subnet Mask (On a home network, it is 255.255.255.0)
  • Default Gateway (It is your router’s IP address.)

• Then check the “Validate settings upon exit” option to help Windows check your new IP address quickly as well as the other relevant information to make sure that it’s working.
• Once you’re done, click the OK button and close the network adapter’s properties window.

Option 2 – Assign Static IP address using Settings

• First, click on the gear icon for Settings and select the Network & Internet tab.
• Next, select Wi-Fi > Current connection where you’ll have to select the network connection your computer is connected to.
• After that, scroll down until you reach the IP settings section and then click the Edit button.
• Now click the drop-down arrow when the IP settings window pops up and select the Manual option.
• Now turn on the IPv4 toggle switch and set the static IP address. You also have to set the Subnet prefix length (subnet mask). For instance, if your subnet mask is “255.255.255.0”, then the subnet prefix length in bits should be 24.
• Afterward, configure the Default Gateway address and the Preferred DNS address and then save the changes you’ve made.

Option 3 – Assign the static IP address using Windows PowerShell

• In the Start Search, type “PowerShell” and right-click on Windows PowerShell from the search results to open PowerShell with admin privileges.
• After that, enter this command to view your computer’s current network configuration: Get-NetIPConfiguration
• Next, take note of the following information:
  • InterfaceIndex
  • IPv4Address
  • IPv4DefaultGateway
  • DNSServer

• Once you’re done, execute this command to set a static IP address: New-NetIPAddress -InterfaceIndex 15 -IPAddress 192.168.29.34 -PrefixLength 24 -DefaultGateway 192.168.29.1
• Afterward, change the default gateway with the default gateway address of your network and make sure that you change the InterfaceIndex number with the one that corresponds to your adapter and IPAddress with the IP address you want to assign to your computer.
• Now execute this command to assign a DNS server address: Set-DnsClientServerAddress -InterfaceIndex 4 -ServerAddresses 10.1.2.1
• Finally, save the changes you’ve made and restart your computer.
