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.

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.

Create a portable anti-malware for removing malware

Here’s another solution which is utilizing a portable USB antivirus software that can check your system for malicious software without the need for installation. Adopt these measures to run the anti-malware on the infected computer system. 1) On a clean computer, install Safebytes Anti-Malware. 2) Plug the Thumb drive into the uninfected computer. 3) Double-click the exe file to run the installation wizard. 4) Pick a USB flash drive as the location when the wizard asks you where you want to install the program.

Mac OS

A solid reason to switch to Mac from Windows PC is Mac OS. Based on Linux, offers more stability and better security than Windows but you will not be able to find a vast array of applications on it.

Even when Mac OS X (the first big one) was first introduced, it looked and felt like ages beyond Windows (Microsoft just recently made a slick and modern design with Windows 11). Under the hood, it turned out that the operating system itself is stable and incredibly fast & responsive. If you value stability and easiness of use, Mac OS is the Operating system for you.

Apple ecosystem

This one is easy, if you are already invested in apple devices like iPhone and iPad, having an apple computer is one step forward into the apple ecosystem and one more step into easy sharing of documents and data between devices.

Calendars, emails, photos, videos, documents, and many more can easily be shared and synched between devices with a single apple ID making workflows much easier than on other operating systems.

Development

Developers all around the world say that developing on Mac is much better and smoother than on PC, this has probably to do something with OS being based on Linux but whatever the case is, it is much smoother and it just feels better. Apple laptops are often the go-to choice of developers for a reason.

Also if you are in the development business for applications and services aimed at iPhone or iPod then there is no really another way than to be into the apple ecosystem and own apple hardware.

Professional software

A lot of professional-grade software exists for both the Windows platform and Mac OS but there is some software that exists exclusively for Apple hardware like Final Cut Pro or Logic Pro. Both applications are used by professionals and are industry-standard software.

Logic pro is used by industrial audio specialists all around the world and is used in professional studios. Final Cut Pro is also used worldwide by video editors and if you are specializing in any of these two fields Mac seems like a very reasonable platform since the software can not be found on Windows. These two are examples, there are other similar applications that are only available on Mac OS

Longevity

Apple hardware is made of high-quality materials and components and it is proven over time that it lasts longer than usual. There are iPhones out there that have 13 years and they are still working, G3 and G4 Macs that are still functional.

When buying Apple products they will outlive other ones if treated properly so in the end you could be saving money by purchasing them.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted. You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them. Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.

NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.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. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.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 it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys 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.
