A Guide to Fixing Error 0x80004005

After a lot of backlash about choosing the default Windows browser, Microsoft has officially backed up and brought back a one-click browser change into Windows 11. For anyone who is not aware, when Windows 11 was released if you wanted to switch to another browser you had to go into the settings app and choose the default browser for different types of file extensions like HTML, HTM, PDF for opening on the web, etc. Of course, this was completely unnecessary and it was not well received by users. So after some time, Microsoft backpedaled to standard one click, choose your default browser solution that existed in the previous version of Windows OS. Altho sometimes Microsoft knows how to irritate its users base, it is good to know that they can also listen and fix things that are required.

The Free Wifi Hotspot is offered to users that own a laptop and a desktop PC that has a wired connection to the Internet and no WiFi modem. The Free Wifi Hotspot is said to help users share their Internet connection with mobile devices that support the 2G/3G/4G/USB tethering connectivity. However, users will need a 2G/3G/4G modem attached to the computer/laptop with access to the Internet if they intend to benefit from the Free Wifi Hotspot software. Additionally, the Free Wifi Hotspot may collect data like your Internet history, downloads log, and software configuration for product placement optimization. PC users that run the Free Wifi Hotspot software may be shown pop-up windows with marketing materials from time to time and maybe redirected to promotional offers.

Several anti-virus applications have flagged Free Wifi Hotspot as a Potentially Unwanted Applications and may come bundled with other PUP-s that may harm your computer or steal some information, due to these risks it is marked for optional removal.

About Potentially Unwanted Applications

Everybody has experienced it – you download a piece of free application, then you see some unwanted applications on your computer or find a strange toolbar has been included with your browser. You didn’t install them, so how did they appear? These unwanted applications, which are referred to as Potentially Unwanted Programs, or PUPs in short, typically tag along as a software package when downloading the application and can ruin your PC or cause major annoyances. PUP does not involve malware in the traditional sense. The reason is, the majority of PUPs end up in a computer not because they slip through the security holes, for example, but because the users have got installed them themselves – totally unintentionally needless to say. A PUP might not be regarded as malicious or harmful but nonetheless, it is a standard reason for clunky OSs; some PUPs are a lot more aggressive by deliberately slowing down your computer or laptop.

How does unwanted software impact you?

Unwanted programs come in many forms. Usually, they can be seen in adware bundlers that are known to utilize aggressive and misleading advertising. The majority of bundlers install many adware programs from several vendors, each of which has its own EULA policy. Safebytes Anti-malware totally eliminates this threat and safeguards your machine against PUP or adware infection. The PUPs likewise get installed into your computer in the form of browser add-ons and toolbars. They will modify web browser settings, change the default search engine, substitute the default home page with their very own websites, slow down browsing speed, and also will ruin your system also. Potentially unwanted programs apply aggressive distribution methods to get onto your personal computer. The worst part of installing a PUP is the spyware, adware, and keystroke loggers that may hide inside. These are software programs that don’t do anything good for you; in addition to occupying space on the hard disk, they will also slow down your PC, often change settings without your approval, the list of troublesome features goes on and on.

Tips on avoiding PUPs

• When installing anything on your desktop, always read the fine print, like the license agreement. Do not accept terms of use that are for bundled programs. • Don’t accept standard, express, default, or any other installation settings which are recommended. Always opt for “custom” installation. • Make use of an antivirus program to boost your protection. Anti-malware programs like Safebytes Anti-malware has got real-time features that will block PUPs before they harm your computer. • Avoid adding freeware software you won’t make use of. Nowadays ‘freeware’ isn’t actually freeware – but ‘crapware’ bundling nonsense. • Always download programs from the original website. Most PUPs find their way onto your PC is through download portals, so avoid it entirely. Comply with these tips and you will almost never get potentially unwanted programs on your computer.

How To Get Rid Of Malware That Is Blocking Antivirus Downloads?

Every malware is bad and the level of the damage can vary greatly depending on the type of malware. Some malware sits in between the computer and the internet connection and blocks some or all websites that you really want to check out.

Technical Details and Manual Removal (Advanced Users)

If you’d like to perform the removal of Free Wifi Hotspot manually instead of using an automated software tool, you may follow these steps: Go to the Windows Control Panel, click the “Add or Remove Programs” and there, select the offending application to uninstall. In case of suspicious versions of browser extensions, you can actually remove them via your web browser’s extension manager. You’ll probably also want to totally reset your internet browser to its default configuration settings. To ensure the complete removal, manually examine your hard drive and Windows registry for all of the following and eliminate or reset the values accordingly. Please remember that only professional users should attempt to manually edit the registry because incorrect file removal leads to a major problem or even a computer crash. Furthermore, certain malware is capable of replicating itself or preventing deletion. It is advisable that you carry out the removal procedure in Windows Safe Mode.

Windows users need to be on high alert. Microsoft has confirmed a critical vulnerability has been found in all versions of Windows which presents an immediate threat, and you need to act now. A critical new zero-day hack has been found which affects all Windows versions. Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer. Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived. Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed. You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

Corsair is well known for RAM memory modules for PC but then it has expanded to PC peripherals and even selling some pre-build computers as well in past few years. New Corsair expansion now includes a laptop line, starting with their new gaming laptop Voyager.

Voyager laptop is packed with a mechanical keyboard and MacBook-like touch bar for your typing and pointing needs. It is built with a 16-inch QHD+ screen packing 240Hz that is run by Radeon 6800M GPU. Also inside lurks AMD 16 thread Ryzen 9 6900HS CPU, Wi-Fi 6E support, Dolby Atmos audio, and full HD 1080p WEB camera.

The keyboard has low-profile mechanical Cherry MX switches with per-key RGB lightning and above is what Corsair calls a macro bar, with 10 shortcut buttons and a small LCD in the center.

Corsair is also including a few features that tie in with its other products. Many of the company’s keyboards, mice, and other accessories use the ‘Slipstream’ USB wireless adapter, which is built into the Voyager laptop. The macro bar is also configured using the same software used for the Elgato Stream Deck, a popular product sold by Corsair.

Windows 11 has brought us a new and revamped settings application that will cover most personalization and overall settings for your operating system. But as much as the new settings app is tweaked and modified there are still some things that can be modified only inside Control Panel. Since the Control Panel icon itself is somewhat not right away once clicked on the start button we are presenting you a couple of ways to open it so you can change each detail you want.

Via Start menu

The most straightforward and easiest way to reach and open the control panel is via the Start menu. In order to do it just click on the Start menu and type in the control panel. Then click on Control Panel Icon in the results.

Pin Control panel icon to the taskbar

In order to actually pin the control panel to Taskbar, you will need to open it first. Use the previous simple and fast steps in order to quickly open it then in the taskbar right-click on its icon. Choose Pin to Taskbar and close control panel. Now you can open the control panel quickly just by clicking it on its icon in the Taskbar.

Add Desktop icon

If you liked the idea to have an icon that you can click in order to fast open the control panel but you are not very fond of the icon being located in your Taskbar then let's place it on Desktop instead. In order to place a special control panel icon on the desktop, we will use Windows setting app. Open settings app with ⊞ WINDOWS + I and go to Personalization tab. Inside the personalization tab, go to Themes and click on Desktop Icon Settings. Check the box beside Control Panel and click on OK. The Control Panel icon will appear now on your Desktop and you can double click on it to launch it.

Run Control Panel from the Run dialog box

Same as in the previous version of Windows you can also open the Control Panel via Windows built-in run menu. This is mostly the preferred way to gain access to it by system administrators. Press ⊞ WINDOWS + R to open the run dialog. Inside dialog type in control and press ENTER. Control Panel will open right away.

A lot of Windows users, use a second GPU for their computer systems, especially gamers above the dedicated graphics card. The operating system is set such that the dedicated high-end graphics card is set to default but there are times when the system does not recognize or detect the second graphics card. Even though every computer system comes with an integrated graphics card, for the most part, it is insufficient for graphics-intensive games and software which is why if you have an extra dedicated graphics card and your computer does not seem to detect or recognize it, then this post is for you. It could be that the dedicated graphics card has failed or it could also be an issue with the drivers and so on. Follow the suggested options below to resolve the problem.

Option 1 – Update your Graphics drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 2 – Update the BIOS

Take note that you have to be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 3 – Try changing the GPU settings

• Right-click on any empty space on your Desktop and select Graphics Properties. Note that the Graphics Properties screen depends on the graphics drivers installed on your computer and are system-specific as they may be different for other systems but they aren’t hard to find.
• After that, make sure that the dedicated Graphics card is selected as Default under the Select Display drop-down.
• If the Graphics card isn’t set as Default, set it and click Apply and Exit.

Option 4 – Try disabling the driver for the integrated Graphics card

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, expand the list of Display Adapters and then right-click and select Disable device for the Integrated Graphics card. However, if the dedicated Graphics card fails, the display won’t work so you need to restart the system and enable it.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

The Intel Driver and Support Assistant automatically identifies, finds, and installs drivers in a computer and is pre-installed in newer Intel-supported systems. If you are using one of those newer Intel supported systems but encountered an error that says, “Communication with service process failed, Tray cannot start” when you launch a program, read on as this post will guide you in fixing this problem. This kind of issue in Intel supported system could be due to some third party application that’s meant to update drivers could be interfering. It is also possible that the Intel Driver and Support Assistant application is corrupted. Whatever the cause may be, here are some suggestions you have to check out to resolve the problem.

Option 1 – Try to uninstall all the third party driver update applications

One of the reasons why some users install third-party driver update software is that it is kind of tiresome to update each one of the drivers manually. However, as tiresome as it might be, it is still better than using a third-party driver update application as these kinds of applications could mess up the drivers, and the Intel Driver and Support Assistant is still much better. To fix the error, you have to uninstall the previously installed third-party driver update application on your computer.

• 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 third-party driver update application 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 2 – Try to disable the DSATray in Startup

Another thing about the “Communication with service process failed, Tray cannot start” error is that it keeps on popping up each time you boot your computer. And so to resolve this bug, you can just disable the DSATray from Startup. How? Refer to these steps:

• Tap the Ctrl + Alt + Del to pull up the Security options window.
• From there, select the option to open the Task Manager.
• Once you’re in the Task Manager, go to the Startup tab and look for “DSATray” and right-click on it and then select the Disable option.
• Now restart your computer and you should be good to go.

Option 3 – Try to reinstall the Intel Driver and Support Assistant

If the Intel Driver and Support Assistant is corrupted, you need to uninstall it from your computer. All you have to do is go to Programs and Features like what you did in the first option to uninstall the program. Once you’ve uninstalled it, download the newer or latest version of the Intel Driver and Support Assistant from the official site of Intel and then install it.

As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:

• “0x801c004d – Unable to enroll a device to use a PIN for login”
• “0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”

If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.

Option 1 – Try checking for any available Windows Updates

The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.

Option 2 – Try creating the PIN again

The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.

• Remove the PIN by going to Settings > Accounts > Sign-in options.
• From there, go to the PIN section and click on the Remove button.
• You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
• Restart your computer and then set up a new PIN.
• Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.

• Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
• After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
• Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.

Option 5 – Try to create a new User Account

You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.
