Win Firewall and third party Firewall are off

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

Note: The problem with the keyboard could stem down to a simple issue in its settings so if you have successfully followed the steps for this solution then you should be able to fix the problem.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Keyboard from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

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.

In case you don’t know, when you visit a website that uses HTTPS, it also offers an SSL certificate to the browser in order to verify the website’s identity. Although it may contain lots of things inside it, one of them is the URL of the website. So if the certificate does not match the URL to what you entered, you will most likely get the “Server’s certificate does not match, ERR CERT COMMON NAME INVALID” error which indicates that the connection is not private and the site may try to steal your data but worry not, as this post will guide you in resolving this issue. To fix the ERR_CERT_COMMON_NAME_INVALID error, here are some suggestions that might help.

Option 1 – Check the website’s certificate

If you own the website where you’re getting the error, then you might have to check if the website’s certificate is installed properly and configured on the server as it could be the reason why you’re suddenly getting the error.

Option 2 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why you’re getting the ERR_CERT_COMMON_NAME_INVALID error. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 3 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the ERR_CERT_COMMON_NAME_INVALID error in Chrome. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.

• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Run the built-in Malware Scanner and Cleanup Tool in Chrome

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser. In addition, this built-in tool in Chrome might also help in fixing the ERR_CERT_COMMON_NAME_INVALID error.

Option 5 – Reset Chrome

Resetting Chrome can also help you get rid of the error. Resetting Chrome means restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.

Error 0xA00F4244 or 0x200F4244 is when Windows can not detect the WEB camera in your system and it is usually accompanied by the message: We can’t find or start your camera. There could be several reasons for this error and in this guide, we will cover all of them in order to help you to get back on track and start using your WEB camera which is perhaps now more required than ever in this world we live in.

1. Check privacy settings

   With the latest Microsoft Windows updates come the latest issues and it is not strange that privacy settings can become reset or changed when an update is applied. This is a quick fix to this issue and can be the sole reason why you get this error, go to Windows settings, then to privacy and check to see if the WEB camera is turned OFF, if this is the case turn it back ON and make sure that option Allow apps to access your camera is also set to ON.

2. Check if the camera is enabled

   Sometimes it is by mistake, sometimes by an update but the web camera could be disabled in the device manager of Windows. Right-click on the Windows Start button and click on device manager to open it up, find and expand the cameras category. Right-click on your camera, if it is disabled, you will have the option to enable the camera, if it is enabled and Windows is detecting that it is working fine you will have the option to disable it.

3. Check antivirus settings

   Antivirus and firewall applications are in today's world and life-essential piece of software but they can sometimes create more harm than good, from stopping windows updates to killing important services of applications and preventing internet access being just some examples of their paranoid behavior. Try disabling or turning your protection software OFF and see if your WEB camera will miraculously come back to life. If this is the case, somewhere in the settings of software there is an option that controls this aspect, try to locate it and set it in that way so you are able to use your camera.

4. Reinstall camera driver

   If the previous three solutions failed to produce a satisfactory solution then reinstalling the camera driver might fix the problem. Go to your manufacturer's camera website and download the latest driver for your camera. Go to the device manager and uninstall the driver for the camera, then apply the latest driver and reboot the system.

5. Check connections and cable

   Sometimes an issue is not due to software nature, sometimes it is hardware. Try checking connections and plug the camera in another USB port, twist and turn the cable a little to see is issue cable-related.

6. Check to see if the application supports your camera

   If Windows has detected the camera and is not reporting any issues with it check your application to see if it can detect your camera and that it supports it fully. Sometimes newer applications tend to support only newer camera models. Try to use the camera in other software as well to see if the problem is with the application you are using.

7. Try camera on another computer

   If everything else fails, try the camera on another computer to see if it will work there. If the camera is not working there as well it is probably malfunctioned and broken for good. If it does work there, try to find out what is different in that computer in comparison to yours, maybe it is some service running in the background, certain application configuration, Windows version itself, USB port version, or something else.

When you receive Error 0x800704C8 when trying to move a file inside Windows 10 operation is stopped and it can not continue leaving you with the file in its original location without a copy. Several issues can be the cause of this type of behavior and error and after some digging and analyzing we are bringing you various solutions for this error and how to fix it.

Ownership issues

It turns out that not having ownership of fie can cause this error and prevent you from copying it. For some reason, Windows can assume that file is owned or used by another application or process and thus prevents you from making a copy since you do not have ownership of it. Resolving this particular issue will require you to install a third-party application that is tailored for this kind of task. After some talk and research, we found out that there is a freeware application that can solve this issue quite fastly. Unlocker is the name and the download link is here. Once downloaded, install it and run it. Once inside the application browse to the location where you need to change the ownership, click on it to select it, and click OK. Use the No Action drop drown menu to select Move, then click OK

Antivirus Issue

As with other file and application issues, this error could also be a product of antivirus marking it inaccessible to Windows and thus preventing copy or move operation on it. note: Do not turn off Windows defender since it was proven that it is not the cause of this kind of error, so if you are using only Windows defender you can skip this solution. How temporary turning off each security suite is different and it depends on the application itself we can not cover in detail the procedure here. Go to your security suite manufacturer's website and get information there or if you want, go directly to applications and features inside Windows and uninstall the software.

Visual Studio issue

• If the file you are trying to move is part of a Visual Studio project then the issue can be linked directly to Visual Studio itself, luckily the solution is quite easy. All you have to do it to exit Visual Studio and then run it with administrator privileges.
• In order to run Visual Studio with elevated privileges locate its executable file and right-click on it.
• Choose properties and go to the compatibility tab
• Inside compatibility tab check box that says run this program as an administrator

Corrupted system files

If the previous solutions have 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 file 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 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

1. Open a command prompt, after which you'll run IPCONFIG /all
2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
