Fix File Explorer stuck on Working on it…

Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

If you are trying to install Office but got an error saying, “Something went wrong, Sorry we ran into a problem” with error codes 12002-4, 12007-4, or 12152-4 instead, this indicates that you have a problem with your internet connection. Aside from internet connection issues, the problem could also be due to some programs that block the installation files to be downloaded so when they time out, you get these error codes. There are several options you can try to fix the 12002-4, 12007-4, or 12152-4 error codes. You can try to install Office offline or turn off the proxy server or VPN (if you’re using one). You can also try to temporarily disable your antivirus program or Firewall. Refer to the given potential fixes below to troubleshoot and fix the problem.

Option 1 – Try to install Office offline

The first thing you can do if you encounter the error codes 12002-4, 12007-4, or 12152-4 when installing Office is to download an offline copy of Office especially when you’re certain that your internet connection is slow. Once you’ve downloaded it, install it again. The offline installer will download both the 32 and 64-bit versions of Office. Keep in mind that you must download the correct version.

Option 2 – Disable the Proxy server

The first thing you can do is to try disabling the Proxy server as it might be the reason why you’re getting error 0x80244022 for Windows Updates. To disable the proxy server, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it. In addition, if you are also using a VPN, you can try to disable it as well.

Option 3 – Temporarily disable the Antivirus and Firewall

As mentioned earlier, the downloading of the installation files could be blocked by either the antivirus program or Firewall or it could be both especially when the link seems suspicious. To fix this problem, you have to disable both the antivirus like Windows Defender and the Firewall or any third-party software you might be used temporarily and then download the installation files again. Once the download is completed, make sure to turn on the antivirus program and the Firewall again. On the other hand, you can also try downloading in a different location which also means that you have to try a different network. It could be that the load on the current system is too high which is why it’s not able to offer enough bandwidth to download the installation files of Microsoft Office.

One of the most common ways cybercriminals use to inject suspicious code into devices is by tricking users into installing a malicious program on a targeted device. Oblivious users are vulnerable to such tricks, which is why Microsoft has been working hard in the background to address this issue. Recently, Microsoft announced the availability of a sandboxed version of Windows 10 that runs inside Windows 10 in order to isolate suspected software to run inside it and protect the system from potential threats. This Windows Sandbox feature is a new feature that keeps your computer secure. It is a virtual disposable environment that you can enable. So if suspect any software of being malicious, you can run this software in an environment and ensure that it won’t interfere with any normal processes and would not jeopardize files on your computer. To simply put it, “Windows Sandbox is a new lightweight desktop environment tailored for safely running applications in isolation”. So if the Sandbox is closed, all the residual files, software, and other data are deleted permanently. To enable Windows Sandbox, refer to the instructions provided below. Step 1: You have to make sure that you are running either Windows 10 Enterprise Editions or Windows 10 Pro and that your computer is running build 18305 or newer. Step 2: After that, you have to enable Virtualization to let another instance of Windows 10 running in Sandbox mode. Step 3: Next, search for Windows Features on and off in the search box and then select the appropriate entry. Step 4: From the list, go to the mini window and check the Windows Sandbox and then click on OK. Step 5: Afterwards, in the Cortana Search box, search for “Windows Sandbox” and select the related entry to run it in an elevated window. Step 6: Then from your main computer (host), copy the executable file and paste it inside the Windows Sandbox environment. Step 7: Now run the executable file in the Sandbox environment and use it as you normally do. Step 8: Once you’re done, close the Windows Sandbox application and as mentioned, every data regarding the executable file and the temporary environment will be deleted. Step 9: And for the sake of safety, ensure that there are no modifications made to the host because of the executions in the Sandbox environment. You have the option to contact Microsoft for feedback related to Windows Sandbox. You can use the traditional Feedback Hub if you have any suggestions or any issues. Just fill in the appropriate details and select Windows Sandbox for the feature category under the Security and Privacy section. And if you have any issues related to the execution of and within Windows Sandbox, simply choose “Recreate my problem” then select Start capture to reproduce the issue, and once you’re done, select Stop capture.

One of the preferred ways to upgrade Windows 10 is by creating a bootable USB drive. However, you might change your mind when you encounter an error during the Windows 10 Setup that says, “We can’t find a USB flash drive”. Worry not for this error can be fixed using some suggestions that will be provided in this post. The funning thing about this error in Windows setup is that the computer says it’s not there when it’s clearly there. To fix this problem, you need to check if the USB device is accessible on your computer or you can also try a different USB device. In addition, you could check if there are any issues with both the USB 3.0 and USB 2.0 ports as it could be the reason why you’re getting the error or fix the bad sectors in the USB drive as well as see if the USB drive is set as the primary drive.

Option 1 – Try to check if the USB is accessible on your PC

The first thing you can do to resolve the problem is to check if you can access your USB device from your computer. All you have to do is open File Explorer and check if the USB device is listed there or not.

Option 2 – Try to connect a different USB device

The next thing you can do to fix the error is to try connecting a different USB device, specifically the one that has more significant storage space. You also have to make sure that it’s working on a different PC.

Option 3 – Fix any issues with the USB 3.0 and 2.0 ports

Although the USB 3.0 ports are compatible with the USB 2.0 ports, it does not necessarily mean that there wouldn’t be any problem when you use them which is why it’s best to fix any issues in them or better yet, use a compatible drive.

Option 4 – Try to fix the bad sectors in the USB drive via CHKDSK

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 5 – Try checking if the USB is set as the primary drive

You might also want to check if the USB drive is set as the primary drive because if it is, then it won’t appear on the list. It could also be that the USB drive has a primary disk in it. To undo it, you need to use the DISKPART utility.

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• Next, execute the “diskpart” command to initiate the DISKPART utility.
• After that, type the “list disk” command and tap Enter to display the list of disks on the computer. You have to take note of the drive number or letter of the concerned USB drive.
• Once done, type the “select disk <X>” command where X is the drive letter or number and tap Enter.
• Then execute the “list partition” command to see the list of all the partitions in your computer. It should be listed as 0, 1, or 2. 0 is the primary partition.
• Now type the “select partition 0” command and tap Enter and then type “delete partition” to delete the selected partition.
• You can do the same to the other partitions as well and when you’re done, execute the format command to turn the USB drive into a standard one.

If you were having some problems with your internet connection and you tried to run the Internet Connections troubleshooter but it displays an error message instead that says, “The default gateway is not available”, read on as this post will show you what you can do to fix this error. The first thing you can do to fix this error is to restart your computer and then try to run the Internet Connections troubleshooter again. However, if you still see the same error message, then you might want to troubleshoot the problem further. You can try to install the Network driver or reinstall the Network adapter drivers. You could also verify the power saving mode or reset TCP/IP as well as disable the Firewall temporarily.

Option 1 – Try installing the Network driver

The very first thing you can do to resolve the error is to install the network driver. It is a common solution to this kind of problem and most users encounter it right after a fresh installation of Windows 10. So if you have done this, then you need to install the network driver so that the network adapters can start working. You can find the network driver in the motherboard CD. On the other hand, if you are using a laptop, you might have to use another computer or mobile to download the network driver from the manufacturer’s website.

Option 2 – Update the Network Adapter drivers

If the first option is not applicable to you since you already have network drivers in your computer, you might want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

You could also try to reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 3 – Try to verify power-saving mode

If you are using a Windows 10 laptop, then you should know that the Power Options panel plays an important role. So if you’re getting an error in your laptop, you have to check some settings that are related to the Power Saving mode. To do so, follow these steps:

• Open Control Panel and go to Hardware and Sound and click on Power Options.
• Next, click on the “Change plan settings” option of your selected plan and then click the “Change advanced power settings” option.
• After that, you should see the Power Options window, and here, expand the Wireless Adapter Settings and Power Saving Mode.
• Now make sure that the Maximum Performance option is selected. If it’s not, select it and save the changes you’ve made.

Option 4 – Try to reset the TCP/IP

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:

• In the Windows start the search, type “command prompt” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, execute this command: netsh int ip reset resettcpip.txt
• Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Temporarily disable Firewall

On the other hand, the error could also be due to the Firewall software installed on your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the error “The default gateway is not available” due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not

TPM or Trusted Platform Module version 2.0 is a must-have if you plan on upgrading your system to Windows 11. So what exactly is TPM and do you have it?

What exactly is TPM?

TPM is a tamper-resistant hardware technology tasked with generating and storing encryption keys inside it for better PC security. It can be remotely used to authenticate hardware and software by utilizing a unique endorsement key placed into the hardware itself. This technology can be used for example in BitLocker inside Windows in order to have data on a hard drive encrypted so if the mentioned drive is connected to another computer it would not be able to be accessed since the encryption key is stored in the TPM module. Microsoft is pushing its agenda that Windows 11 must be and must feel like safety first OS which will protect user data and user information and requiring TPM means that each Windows 11 will be secure so no additional software patches will be required for an extra layer of security. Windows 11 will assume that each user has TPM encryption enabled and will be built upon that.

Do you have TPM on your computer?

If your computer or hardware has been purchased in 2016 or later there are very high chances that you already have the required technology to run Windows 11. Unfortunately, many gaming motherboards have not been placing TPM in their boards and you might not have it. Also, there is the option of you having it but it is turned off in motherboard settings making Windows unable to detect it. As you can clearly see there are a lot of scenarios around required tech and honestly it is a complete mess. But lucky for you there are ways to find out do you possess the needed module in order to make an upgrade. On your current computer on which you would like to make an upgrade in your current Windows OS press ⊞ WINDOWS + R to open the run dialog. Inside run dialog type in TPM.msc and press ENTER to open Trusted Platform Module Management on Local Computer. You will immediately receive information do you have the required module. If everything is fine, you are good to go, however, if it says that compatible TPM cannot be found there is a chance that either you do not have needed hardware or it might be turned off inside motherboard settings.

Check motherboard UEFI

If you have a newer motherboard but Windows utility cannot detect TPM there is a chance that it might be turned off directly on your board. In order to check this, you will have to boot up your PC into UEFI either by pressing the corresponding key when it is turned ON or from Windows reboot options. Once you are inside UEFI you need to find security options and see if there is an option to turn ON or enable TPM. Since every motherboard is different and has different UEFI software we cannot cover all of the permutations and the best we can do is hope that provided information is enough. You can also visit your motherboard manufacturer to see instructions for your specific case.

Conclusion

TPM itself is generally an OK idea and I can surely see good sides of it but there is this lurking feeling that generally, Microsoft is not really concerned about the security of our data and that the real requirement for this is trying to battle software piracy. I simply cannot trust company which introduced tons of telemetry tracking through ages and which has done everything in their power to battle non-legal use of their software. I do not promote piracy but I support free choice and besides, who can tell me what will happen if TPM malfunctions, will I lose all of my data forever? It is not so uncommon that TPM has malfunctioned in the past and it is only logical to presume it can do it again in the future but this time we will not have the choice not to use it, we will be forced into it.
