What is Ammyy Admin

AmmyyAdmin is a software developed by Ammy. This software allows you to manage network computers and servers remotely without complicated NAT settings adjustments or Firewall problems. The program is similar in marketed function to TeamViewer or LogMeIn. This software does not require installation and it lets you control other computers or share files over the software. It usually comes bundled with other software. This software copes files into your computer and sometimes creates new startup keys that allow it to start each time your computer is restarted. AmmyAdmin might display additional ads in your browser as well as pop-up ads. Due to its ability to silently install and run remote administration, it could be used maliciously by those who intend to damage your computer or steal data. AmmyyAdmin is flagged for optional removal, and if you did not intentionally install it, removal is highly recommended

What is a Potentially Unwanted Program (PUP)?

If you’ve ever downloaded freeware or shareware, odds are high that your computer can get installed with a bunch of unwanted programs. A PUA / PUP (potentially unwanted application / potentially unwanted program) is a software program that comes bundled with freeware/shareware and you agree to install it on your computer system. These are programs you definitely don’t want on your system simply because it does not give any beneficial service. PUP doesn’t involve malware in the traditional sense. One simple difference between malware and PUP is distribution. Malware is typically dropped through vulnerability exploitation and in contrast, PUP gets installed with the consent of the end-user, who consciously or unknowingly authorizes the PUP installation on their computer. A PUP might not be viewed as malicious or harmful but nonetheless, it is a common cause of clunky operating systems; some PUPs are a lot more aggressive by deliberately slowing down your PC.

How PUPs affect you?

Potentially Unwanted Programs appear in different forms and varieties, but most times, they are adware programs that exhibit irritating pop-up adverts and advertisements on web pages you explore. In addition, most free software nowadays comes with quite a few unwanted add-ons; in many instances a web browser toolbar or browser modification like a homepage hijacker. They’ll modify browser settings, change default search provider, substitute the default home page with their very own websites, decelerate internet speed, and will damage your computer as well. They could look harmless but PUPs are usually spyware. Some might carry dialers, keyloggers, web browser hijackers, and tracking components that will collect system details, or tracks customer habits and relays these records to third-party organizations. Because of this unwanted program, your application might freeze, your security protections could get disabled which may leave the computer susceptible, your system may get damaged, and the list goes on and on.

Tips on protecting yourself from unwanted software

• When installing anything on your PC, always read the fine print, including the EULA. Do not accept terms of use that are for bundled programs. • Select the “custom” install whenever downloading a software program. Particularly, pay attention to those small boxes which have been checked as default, where you might ‘agree’ to receive advertisements or install software bundlers. • Use anti-PUP software. Security applications like Safebytes Anti-Malware offer the very best real-time protection from PUPs and also other malware. • Be alert if you download and install freeware, open-source programs, or shareware. Avoid downloading and installing browser extensions and programs you are not knowledgeable about. • Use only official product sites for downloading applications. Avoid download websites completely since the majority of websites force users to download the software using their own download manager, which is often bundled with some kind of unwanted program.

Safebytes Anti-Malware scans and detects malware for free. To complete removal, and ensure full PC protections, a paid license key is required.

Malware could potentially cause a lot of damage to your computer. Some malware sits in between the computer and the net connection and blocks a few or all internet sites that you would like to check out.

Once you’re in Safe Mode, you can try to download and install your anti-malware software program without the hindrance of the malicious software. Following installation, run the malware scanner to eliminate most standard infections.

Obtain the security program in an alternate web browser

Certain malware may target vulnerabilities of a specific web browser that obstruct the downloading process. If you seem to have a virus attached to Internet Explorer, then switch over to an alternate browser with built-in security features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Error Code 0xc004fc03 – What is it?

Error code 0xc004fc03 occurs when Windows users fail to activate their Windows operating system due to a networking problem. The error code’s common symptoms include the following:

• Inability to activate Windows 10 operating system
• Message box with error code 0xc004fc03

Solution

Error Causes

Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers.  Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.

Further Information and Manual Repair

To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.

Method One: Verify Internet Connection

To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.

• Step one: Click the Start button and select Settings
• Step two: Select Network & Internet
• Step three: Click the Status section of the Network & Internet tab

If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.

If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.

Method Two: Check Firewall Settings

Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.

• Step one: Click search bar and type firewall
• Step two: Select Windows Firewall
• Step three: Select Turn Windows Firewall on or off

In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.

Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.

Method Three: Activate Windows by Phone

Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.

• Step one: Select Settings
• Step two: Click Update & security
• Step three: Select Activate by phone
• Step four: Follow the instructions provided thereafter.

This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

Free Ride Games is a desktop casual game program and potentially unwanted application. It sets its player to run in startup boot with Windows and installs additional files outside of its designated installation folders. The software reads PC information to display targeted advertising and runs a background process that cannot be shut down even by exiting the FreeRide Player. The player runs in full screen with no visible window controls to exit or minimize, and contains unskippable advertising in its function. While not malicious, the FreeRide Player possesses many traits that as of publication time have caused some AntiVirus programs to designate it as potentially unwanted adware. It has also been associated with adware distribution toolbars such as GameVance.

About Browser Hijackers

Browser hijacking means a malicious code has power over and modified the settings of your browser, without your consent. Browser hijacker malware is created for a variety of reasons.

Also, certain freeware and shareware can put the hijacker in your computer through the “bundling” technique. An example of some notorious browser hijacker includes Conduit, Anyprotect, Babylon, DefaultTab, SweetPage, Delta Search, and RocketTab, but the names are constantly changing. Browser hijacking can lead to serious privacy issues and also identity theft, affect your web browsing experience by taking control of outbound traffic, substantially slows down your personal computer by depleting a lot of resources and lead to system instability as well.

How to remove a browser hijacker

However, most hijackers are difficult to eliminate manually. Regardless of how much you attempt to get rid of it, it might keep returning again and again. Furthermore, manual removals demand in-depth system knowledge and therefore can be an extremely difficult task for beginner computer users.

Dune, arguably one of the best science fiction novels ever written was brought to a big screen first time by David Linch. Sadly movie itself went through development hell and a lot of troubles and the end result was somewhat strange. The audience was divided on it, some hated it, some loved it but for sure it left a mark in cinema history. Years have passed and just when people forgot about ever receiving another try on a book adaptation Denis Villeneuve has brought his vision of Frank Herbert's novel into its full glory on a big screen. The interesting thing about this new Dune movie was that from the start Denis envisioned it as a two-movie part openly saying that book itself is too complex to be done in a single movie. But, the issue arises when information about Dune part two was hanging on a thread on how well Dune part one will be received and performed in the box office. This naturally brought all kinds of speculation and worry among fans of the franchise, especially because the movie itself was really good and well made. Well for all of you fans and people who wanted to see a continuation of the story can rest at peace now since the Legendary picture has officially announced and green-lighted Dune part two. The budget was given and we can expect part two at the beginning of 2023.

If this is not fixed on the time it may lead to serious disk damage and registry corruption eventually resulting in system failure. System failure can make you lose all the valuable data saved on your system for good.

How to Fix the Error Code 0x8007045D?

Error codes on your PC are like warnings. These codes indicate that your PC has some issue. Therefore ignoring it is not wise. To spare yourself from such serious PC damages, it is advisable to take correct measures timely instead of prolonging and making the situation go from bad to worse.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• 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.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the Wdf01000.sys Blue Screen error, you need to use the Driver Verifier Manager:

• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 4 – Run the System File Checker Scan

Over time Applications change, some for the better some for worse. Some of them even stop receiving updates and are old and vulnerable. Sometimes standards change and some file types are not used anymore. Software evolves along with technology and that is good. Keeping old and useless applications inside your Windows is not so good. From various exploits to simply taking up space, maybe even slowing down OS it is always wise and good to clean your Windows from unwanted old applications. In this article, we will be mentioning some relics of old and providing you with an explanation of why you should remove them from your system if by any chance you still have them on it.

Silverlight

Silverlight was meant to be a competitor for Adobe Flash, it is a WEB framework that enables rich media content inside your WEB browser. The issue is that it is not developed anymore and today's browsers do not support it. The only browser that actually can support it is internet explorer which itself is not supported and how there is practically 0 content on today's modern WEB that will require Silverlight, it is safe and recommended to remove it.

Adobe Flash

Speaking of Adobe Flash, you should remove it as well. Flash has stopped receiving support as of January 2021 and browsers have dropped support for it and even blocked it due to security issues. However, there still might be some local installation of Flash itself inside Windows along with the old Shockwave player that stopped receiving support in 2019. You should remove them both.

JAVA

Now this one is tricky, by itself JAVA does not present any security issues since browsers do not support it anymore and the desktop version is not really slowing down your computer. This one has simply put just another media runtime that is not used and simply takes up space and resources. However if you have some applications that you do use that rely on it (I can really just think of JAVA Minecraft at this point) leave it of course but in any other case, it is just purely not needed.

Quicktime

While we are at media runtime and stuff that just simply is not needed, Quicktime is one of them. Now this Apple Video player and codec is still pretty developed and active in Apple’s iOS environment, Windows version has not been updated since 2016 and it was discovered that it contains some critical vulnerabilities. Uninstall it and if you need a player that could play MOV files, just use a VLC player that can play them without any separately installed codec.

uTorrent

This one, the same as CCleaner was once a good application, as a matter of fact, it was the best torrenting application. Sadly it has fallen from its grace very low, from getting tons of ads in its interface to findings in 2015 that code of torrent client was packed with a crypto miner that used system resources of an installed computer to mine crypto without user’s awareness. You should uninstall this torrent client if you would like to get your PC back and not provide it for cryptocurrency mining for the company that developed it. Use qBittorrent or TIxati, open-source and free ones that have everything needed for any torrenting needs.

Toolbars and Browser extensions

There are a lot of toolbars for browsers and extensions that are malicious in nature or simply not updated providing security issues. It is very advisable to remove this as soon as possible.

WinRAR

WinRAR has gained its large popularity solely for the reason that you could download it from the official site like shareware and use it forever. The license never expired and you could use it indefinitely. Sadly not much has been improved in the application itself and it is slowly falling out in its range of what it can do. There are better open source and free options today like 7zip, PeaZip, ZIPvare, and more that are working the same as WinRAR if not even better.

Windows and manufacturers Bloatware

Yes, applications that come bundled with Windows and with some laptops that include manufacturers made software for different tasks like its own specific media players, calculators, etc. It is known that these applications are not better than their open-source rivals and there are too many of them including some that you will probably never use. It is the same as buying a new phone bundled with tons of applications that you do not need, did not ask for, and do not use. Delete all of them. Considering Windows there are also some Store application like Candy Crush Saga demo and other are safe to remove if not needed. That’s it, our advice for old and not needed applications so you can keep your PC safe and fast.
