If you receive an error message saying, “The proxy server is refusing connections” while trying to open a website on your Google Chrome or Mozilla Firefox browser in Windows 10, then read on as this post will guide you in fixing this error. This kind of error occurs when you have a wrong or dead proxy configuration or when you are using some VPN service. However, this kind of error could also mean that your computer might be infected by malware which caused some changes in the internal settings. Whatever triggered the error, here are some suggestions that could help in fixing it.

Option 1 – Check the proxy settings in your browser

Like other browsers, Firefox allows users to set up proxy in several ways. However, if you’ve made any changes recently which might have caused the error, the first thing you can do is to check the proxy settings in your Firefox browser. Follow the steps below to do so.

• • Open the browser and go to Menu and then click Options.
  • After that, go to the General tab and scroll down and click the Settings button under Network Settings.

• From there, make sure that the Use system proxy settings option is set. If not, you have to enable No proxy and then save the changes made.
• Now check if the “The proxy server is refusing connections” error is fixed or not.

Note: If you want to use a proxy in Firefox, you have to select the Manual proxy configuration and set it up properly. And if your network has a proxy setting and you want to grab that, you have to opt for the Auto-detect proxy settings for this network option.

Option 2 – Try disabling the proxy server for your LAN

If your PC was just attacked by some adware or malware as of late, it is possible that it has changed the network settings in the system and might display spam advertisements. Thus, you have to disable the proxy server for your LAN. To do that, refer to these steps:

• 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.

Option 3 – Try disabling the manual proxy setup from Settings

In case you miss it, there is actually an option in the Settings panel that you can use to set up a proxy in your Windows 10 computer. So if you encounter the “The proxy server is refusing connections” error, you should disable manual proxy for the meantime and check if it fixed the error or not.

• Tap the Win + I keys to open the Windows Settings.
• Then go to Network & Internet > Proxy.
• And on your right-hand side, ensure that the Automatically detect settings are enabled and that the Use a proxy server option under the Manual proxy setup is disabled.
• Now try to open any website again and see if the problem’s fixed.

Option 4 – Check your VPN

If you are using a VPN application, there are times when it causes some issues like this error. If that’s the case, you can try to disable your VPN temporarily and see if the error is resolved or not and if turns out that your VPN is the culprit, you have to uninstall it and install a new one or its latest version. To uninstall it, follow the steps below.

• 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 VPN service you are using, 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 5 – Clear your browser’s internet cache

You actually have the option to Hard Refresh in order to clear the cache of your browser either pressing key combination Ctrl +F5.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the “The proxy server is refusing connections” might be caused by some malware in the system and so to eliminate the malware, 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.

If you are checking for an update on your Windows 10 PC and you got the error 0x80070005 due to some ACCESS DENIED permissions issue, then read on as this post will show you what you can do to fix the problem. For some reason, the Windows Update does not have enough rights or permissions to continue further which is why you’re getting an error instead. Thus, the first thing you can do before you troubleshoot further is to make sure that you’re logged in as admin. However, if you’re already logged in as one, then here are some suggestions that might help you fix the Windows Update Install Error 0x80070005.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error 0x80070005. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Take control of the User App Data

There are times when permission to access the files is not configured correctly. As a result, it blocks the downloading of the updates. Thus, you have to take full control of the User App Data which is placed at C:/Users/USERNAME/AppData.

• First, go to C:/Users/USERNAME/AppData 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 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.

If you are trying to log into your user account on your Windows 10 computer but encountered an error message instead that says, “Your account has been disabled, Please see your system administrator”, read on as this post will guide you on how you can fix this problem. In this kind of scenario, you won’t be able to access your data unless you have access to the administrator account. This problem could be caused by several problems. It is possible that malware has infected your computer and has changed some settings in your computer, especially if your system has been under a malware attack not too long ago. The malware could’ve changed the “Account is disabled” option. The only thing you can do to resolve this kind of problem is to log into your computer using another administrator account and then change the setting. However, if you don’t have a second administrator account, you can just enable the built-in hidden administrator account on your computer. You shouldn’t have any problem enabling the hidden administrator account as it is quite easy when you can log into your account. And in this post, you will be guided on how you can enable the hidden administrator account using the Registry Editor to fix the “Your account has been disabled, Please see your system administrator” error.

To get started, follow the instructions given below.

1. First, you need to start your computer and ensure that you are on the error screen. From there, you will see the Power options located on the right-hand side.
2. Click on the Power options and tap and hold the Shift key and then select Restart.
3. After that, the Advanced Boot Options will appear and from there select Troubleshoot > Command Prompt.
4. Next, you have to select your user account and enter the user account’s password to open Command Prompt.
5. After opening Command Prompt, open your screen and type “Regedit” and then tap Enter on your keyboard.
6. Now select the HKEY_LOCAL_MACHINE in the Registry Editor and go to File > Load Hive.
7. Afterward, you have to open the Windows installation drive and go to the location – WindowsSystem32Config
8. From there, you should find a file named “SAM” – select this file and click the Open button.
9. Next, you have to enter a key name. You can just input whatever you prefer.
10. Once done, navigate to this path: HKEY_LOCAL_MACHINEkey_nameSAMDomainsAccountUsers
11. From this path, you will see a key named “000001F4” – select this key and double click on the “F” entry that you can find on the right-hand side of the screen.
12. After that, look for the value data line labeled “0038” which should show 11 in the first column. You have to replace it with 10.
13. Once done, click on the OK button and close the Registry Editor and the Command Prompt to restart your computer.
14. Now once your computer has restarted, sign in to the Administrator account and open the Computer Management window. You can just search for it using the search bar in the Taskbar.
15. After you open Computer Management, go to Local Users and Groups > Users – where you can find all the user accounts. Look for your deleted user account and right-click on it and select Properties and then unmark the checkbox that says “Account is disabled”. This should fix the problem.

What is OpenCandy?

OpenCandy is an application that downloads and installs software, including other Internet Browsers to a computer system. Used as a bundle, this application installs additional programs that you may knowingly or unknowingly agree to install. Since most users don’t accept the challenge of reading the EULA in its entirety, they tend to download bundled applications unknowingly.

Assessment of OpenCandy PUP

During the initial assessment of OpenCandy, I was a little skeptical about what to look out for or expect. In fact, I had to install the OpenCandy.exe file twice to discern its behavior. I’m not sure how this application got its name but I do believe it has something to do with the fact that it supposedly helps Internet users open a new world of Internet browsing. That conclusion was arrived at after realizing that OpenCandy.exe installed mostly Internet browsers along with a tune-up tool on the test computer. However, as a result of the system requirements, there was a pop-up message indicating that Internet Explorer 8 was not compatible with the computer system in question. In comparison to the malware I’ve encountered since I started researching malware, OpenCandy is everything but malicious. In fact, this application is only categorized as malware because of its’ subtle covert nature of installing bundled programs unsolicited by the user. Additionally, OpenCandy coerces users into changing their Internet Browsers by installing those unrequested by the user. In fact, it’s no shock that OpenCandy chose to install the Internet Browser ‘Opera’ as a part of this bundle since it’s one of the least used browsers according to the Federal Government. Clearly, this was a smoothly disguised advertisement or promotion to force users into using the Opera Browser, along with Internet Explorer 8.0. While these aforementioned browsers in themselves aren’t malicious and are in no way considered malware, they were installed as a promotional tool and without the request of the user. Despite being mentioned within the EULA, advertisers are capitalizing on this since most users do not bother to read the agreements when installing a program. Furthermore, OpenCandy, like most other bundled applications I’ve dealt with, threw in a tune-up tool as a part of the promotion. I found this tune-up application annoying since I had to hassle my way into getting it to close from the computer screen. I can only imagine the hassle users would go through trying to remove this software. Image 7: Depiction of a scan performed by Tuneup Utilities. The scan detected that several areas on the test PC could be optimized/tuned up. Image 8: After a scan was completed using the Tuneup utility program, I was given an option to buy the full version. Nothing is wrong with this marketing strategy. In fact, most utility tools if not all will scan your computer to detect threats or loopholes, but they won't exactly allow you to fix those problems unless you buy the full version. It's not unfair, it's just business. Programs installed during the installation of OpenCandy include:

• Web Companion: Developed by Lavasoft, Web Companion is said to be an application that serves as a security defense for your Internet browsers by preventing unauthorized changes (see image below)
• Tuneup Utilities: Tuneup Utilities does exactly as it says. It cleans up a computer system, whereby preventing unused programs from slowing it down.
• Opera Stable 30.01.1835.88: Opera is a fast, simple, and effective Internet browser that allows users to get around on the web.

All in all, the intent of installing an application such as OpenCandy is to unleash a world of promotion or advertisements on your computer. They are pretty annoying and in some cases difficult to remove. Furthermore, as a user, you want to control what gets installed on your computer without being dictated to or coerced in some EULA that you probably overlook.

A lot of Windows 10 users have reported recently that their computers are frequently crashing with a Blue Screen error with an error code “VIDEO_DXGKRNL_FATAL_ERROR”. This kind of Stop error appears not so often and its bug check value of 0x00000113 is an indication that there is some violation in the Microsoft DirectX graphics kernel subsystem. This error also occurs when there is a corrupted driver that interferes with the GPU’s normal functionality. According to some security experts, this kind of error is reported to only occur in Windows 10 PCs. Users started getting this error right after a large Windows Update. The cause of this error might have something to do with a violation in the DirectX graphics kernel subsystem where there could be a bad DirectX install or some corrupted Dynamic Link Library or DLL. Aside from that, the error might also be caused by the Nvidia driver which might have crashed or it could also be that there is an intermittent power supply. Moreover, an outdated BIOS as well as a third-party security program might be the ones behind this Blue Screen error. Whichever the case may be, you need to fix the VIDEO_DXGKRNL_FATAL_ERROR BSOD error by following the instructions given below carefully.

Option 1 – Try checking if the NVIDIA graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the NVIDIA graphics card is enabled or not. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• After opening the Device Manager, look for the Nvidia graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
• Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Update or uninstall third-party security program

As mentioned, the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen error might be caused by a third-party security program that’s installed on your computer. So you have to either update it or uninstall it to resolve the issue.

Option 3 – Check the power supply for any inconsistency

The Blue Screen error might also be caused by an intermittent power supply. If there is any intermittent changes between the main supply and the battery power, it might lead to bad contact on your supply to the charger and thus, causes the VIDEO_DXGKRNL_FATAL_ERROR Stop error to appear. So to check if this scenario is applicable to you, you have to monitor your computer for any frequent changes between the power supply and the battery power. If you see that the supply is displaying power On and Off, see if the same goes when the power supply is disconnected. However, if it does not occur, you might have to purchase a new power adapter cable and replace the one that you have right now.

Option 4 – Reinstall the Graphics card drivers

• Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Display adapters and uninstall each one of the graphics card drivers by right-clicking on them and selecting the Uninstall device option.
• After uninstalling the graphics card drivers, close the Device Manager and tap Win + R to open Run once again.
• After that, type “appwiz.cpl” in the field and hit Enter to open Programs & Features in the Control Panel.
• Next, look for any program that’s related to your GPU manufacturers like Nvidia, AMD, or Intel. Right-click on any GPU-related entry and click on Uninstall to uninstall them and then follow the next on-screen instructions that appear afterward.
• Now restart your computer.
• Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
• Restart your computer once again. That should fix the problem.

Option 5 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the BSOD error. You can just go to the OEM’s website as they offer utility software that can download BIOS firmware and update it without any problem. BIOS updates usually offer enhancements and fixes to some issues like this one.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
