Fix Error 0x8004230F when creating Restore
Creating a System Restore point is definitely a must especially when you are about to make some changes to your computer. This will help make sure that the system settings and files can go back to an earlier point, should something go wrong, without affecting any personal files. However, there are cases when creating a System Restore Point does not go smoothly and you encounter an error that says, “The shadow copy provider had an unexpected error while trying to process the specified operation ( ox8004230F )”. Aside from creating System Restore Point, you can also encounter this error when you create a system image or backup. According to reports, this error pops up when the required services are not running or not properly responding. And to fix it, there are several recommendations that will be provided in this post to fix the Error 0x8004230F when creating System Restore point in Windows 10. You can try to check the Volume Shadow Copy Services status or run the VSSADMIN tool. You could also check the status of the Microsoft Software Shadow Copy Provider Service or create System Restore Point in a Clean Boot State. For more details, refer to the provided options below.

Option 1 – Try checking the status of the Volume Shadow Copy Service

  • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
  • From the list of services, look for the Volume Shadow Copy service and double-click on it.
  • After that, this will open the Properties where you have to make sure that the Startup type is set to Automatic (Delayed Start) and then click on the Start button underneath it.
  • Once done, click on Apply and then OK to save the changes made.
  • Now try creating a System Restore Point again and see if the error is already fixed or not.

Option 2 – Try to run the VSSADMIN tool

In case you don’t know, the shadow copy provider is sensitive and some other backup, disk cloning, etc. can make it malfunction. To fix this, you can run the VSSADMIN tool by following these steps:
  • Tap the Win + R keys to open the Run dialog box and type “cmd” and hit Enter to open Command Prompt.
  • Next, execute this command to check if you have other third party VSS admin providers: vssadmin list providers
  • After that, if it finds any, you need to disable them but if it does not find anything, then proceed.

Option 3 – Try to check the Microsoft Software Shadow Copy Provider Service status

  • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
  • From the list of services, look for the Microsoft Software Shadow Copy Provider Service and double click on it.
  • After that, this will open the Properties where you have to make sure that the Startup type is set to Automatic (Delayed Start).
  • Once done, click Apply and OK to save the changes and then try creating System Restore Point again.

Option 4 – Troubleshot the problem in a Clean Boot State

It is possible that some third-party program installed in your computer might be the one that’s causing the ox8004230F when you try to create a System Restore point. Thus, you can try to boot your computer in a Clean Boot State and then try to perform the task again.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And to configure Windows to use the usual startup, just simply undo the changes.)
  • Once your computer has restarted try to create a System Restore Point again and if it now works, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

What Is a VPN and What Can It Do For You?

Have you been feeling anxious in the digital space? Feeling like you have a million eyes on you each time you visit a website? It can definitely make you uneasy. Luckily there’s an easy fix, and it’s called a VPN.

In this article we’ll take you through the basics of what a VPN does and some of the biggest benefits you can reap from buying one.

VPN: definition and how it works

VPN stands for Virtual Private Network, so its name already says a lot about what it does. 

A VPN is specialized software that keeps your browsing private and secure. Essentially it hides your identity, preventing possible cyberattacks and data theft. This is especially important in cases of public network use, where you’re highly exposed to potential threats.

To be more specific, this software encrypts your Internet Protocol (IP) address by filtering it through a server hosted by the VPN provider first. That way, it prevents your Internet service provider, third parties and lurking online thieves from tracking the actual you.

Some providers, such as Surfshark VPN with its IP Rotator feature, even make it a habit to frequently change your IP address to further protect your identity. With most VPN providers, you can also appear to be in a completely different country, adding to your disguise.

There are tons of advantages you can look forward to if you decide to use a VPN. Take a look at some of the crucial ones.

Benefits of using a VPN

When choosing a VPN, you can find both free and paid options. We recommend you go with the paid ones, since they have stronger security, encryption and data protection, as well as more advanced features. Free VPNs come with limitations and risk of malicious attacks on the software itself.

You can choose to buy a singular VPN service or opt for antivirus software that has a VPN built in, for example Bitdefender’s Ultimate Security plan. That depends on what you use your computer for and how much. 

When you pick one, here’s what it can do for you.

1. Access region-specific content

When we said you could change your location, we meant it. Say you’re using a streaming service and a show you desperately want to watch isn’t available in your country. You can use your VPN to make it look like you’re browsing from a country where it’s unlocked.

This option is also convenient for gamers who want to access maps, skins and other in-game items unavailable in their location.

In addition, you can use this powerful feature when you’re traveling to a region where some of your favorite content may not be accessible.

Do keep in mind that you need to read the Terms and Conditions (yeah, we know - who does that?) of your games and services before doing this, since you could end up getting a penalty. It’s also important to remember that there are entire countries that have strict regulations or even bans on VPNs, for example Belarus, Russia and China. So make sure to be very cautious with your VPN use, friends.

2. Browse like no one’s watching

VPNs shield your browsing habits from prying eyes on the web. Those can be malicious hackers or just third-party cookies tracking your every move to later bombard you with targeted ads. For example, Surfshark VPN features a Cookie blocker that blocks all cookie-related pop-ups and lets you browse in peace (and secret). It works even when the VPN is turned off, which is also pretty neat.

In addition, their CleanWeb 2.0 technology makes sure ads and especially malware don’t stand a chance at all, since they’re blocked before they can even load.

The inability of sites to track your browsing means they can’t collect and analyze any of your data. So, your personal information - or your company’s information in case that’s what you’re using your computer for - is entirely hidden and secure.

3. Save money

It’s well-known that the prices of certain items and services vary based on your location, browsing time, age and many other factors. This most commonly goes for airline tickets and hotel stays.

You can use your VPN to avoid high prices and surcharges. Clear all cookies, turn on your VPN and visit an online shopping site to check out their prices. Then compare your findings with the offers you see when your VPN is off, when you spend a long time on the site or have an active account with the company. 

Sometimes this can really help you find the best deals and avoid breaking the bank. But again, check the Terms and Conditions before you purchase something using a VPN.

4. Secure your smart home

The more smart devices you have connected to your network, the more exposed you are to potential cyberattacks. Phones and computers are generally designed to be decently secure even without a VPN or antivirus, but smart home devices leave a lot to be desired in that regard. 

Protecting your home network with a VPN software means all devices connected to it are secure, be it an air purifier or Alexa.

5. Prevent connection slowdown

Your ISP can intentionally slow down your internet speed based on how much data you’ve consumed (data throttling) or your activities online (bandwidth throttling).

But with a VPN, what kind of data you send and receive and how much is entirely hidden. Therefore, if your ISP can’t see you, they can’t control you and they can’t throttle down your speed.   

The bottom line

You can never be too safe online. So definitely think about getting yourself a solid VPN to pump up your privacy and security as much as you can. And if you have any questions or need help choosing the perfect software for you, feel free to reach out to us.

How to Fix the TWCU.EXE Failed to Load Library File Error in Windows 10
The TWCU.EXE or TP-LINK Wireless Client Utility is a configuration application required to run wireless adapters successfully. The TP-LINK Wireless Client Utility application only exists on computers that are using the TP-LINK adapters. Upon the installation of this application, the service will be automatically added to the Windows service list that will continuously run in the background.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH
If you encounter an error message saying, “ERR SSL VERSION OR CIPHER MISMATCH” while visiting a website, then it is not primarily your fault as an end-user. In fact, it can happen on any website like Chrome, Edge, Firefox, and even Internet Explorer. Getting this error means that the website you are visiting is using an SSL certificate which your browser seems to be rejected because there is some issue with the certificate. It is also possible that the certificate that’s downloaded on your computer is corrupted or that your computer configuration for TSL/SSL is misconfigured. Here are the complete details of the error message:
“A secure connection cannot be established because this site uses an unsupported protocol, Error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH”
To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error, refer to the options given below and see which one works for you.

Option 1 – Try to access the website with the only HTTP

The first thing you can do is to try accessing the website using HTTP instead of HTTPS. If you can open the website using HTTP then it means that the problem is in the website itself. And if you are the website owner, you can check the following:
  • Check if your website’s SSL certificate name is mismatched. Here you need to ensure that the name and alias of the websites match with the actual website URL where the certificate is installed.
  • Second, check if your server is using the RC4 Cipher. If it is, then you need to fix that.
On the other hand, you may also check if your CDN also supports SSL since most of the CDN nowadays supports SSL. All you have to do is configure it correctly and it should be good to go.

Option 2 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR SSL VERSION OR CIPHER MISMATCH error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.
  • Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
  • Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
  • From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
  • Restart the browser.
On the other hand, if you were using Firefox when you go the error, here’s what you have to do.
  • Open Firefox and in the address bar, type “about:config” and hit Enter.
  • If a warning appears, just click on the “I accept the risk!” button to proceed.
  • Next, type in “TLS” in the search field and hit Enter.
  • Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
  • Now click OK and restart Firefox and do the same thing with SSL.

Downloads folder loads slowly in Windows
If you are frequently experiencing slow loading of folders in your Windows 10 computer, Downloads folder for instance, then you’ve come to the right place as this post will help you resolve such issue. Slow loading of folders is a common problem faced by many users even when they are using the latest hardware like SSDs. So if you experience the same thing, be it with the Downloads folder or other folders on your computer, there is a way to resolve that issue and make the folder load faster. Slow-loading means when you attempt to open the folder, it takes a couple of seconds before it displays its contents. In such cases, you’ll see a green loading address bar that says “Working on it” which can get quite annoying especially if you are in a hurry. And if you notice that this only happens in the Downloads folder, there certainly is something wrong. This kind of problem can occur on SSDs and normal hard drives. The main reason behind the occurrence of this problem is that the folder may have been optimized for viewing photos or other media formats which is why it takes quite longer than usual to load all the files and their thumbnails. However, since the Downloads folder usually contains all kinds of files like documents, zip files, audio/video files, etc. there is no need to optimize this folder for media files only because doing so is only going to make the Windows File Explorer slow in loading the folder’s contents and thumbnails which does not exist for many files.

Option 1 – Configure the Downloads folder

  • Right-click on the Downloads folder or the folder you’re having trouble opening.
  • Then click on Properties and go to the Customize tab.
  • After that, click on the “Optimize this folder for” option in the drop-down menu.
  • Next, select General items from the drop-down which might have been set by default to Pictures or Video.
  • You also have the option to apply this template to all the subfolders, that is if your folder has any subfolders.
  • Now apply the settings and restart Windows Explorer.
Note: Once you’ve completed the steps above, it should now make the folder content display a lot faster than before. Now try to open the Downloads folder which would not take much time as you will see the changes right away.

Option 2 – Run CHKDSK to check your disk for errors

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”. This error check utility can help with several issues in the system including File System Error -2147219196.
  • 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 /r /f
  • 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.
  • Once your computer has restarted, try accessing the file and check if the error persists.

Guide How to Remove PCOptimizerPro

PC Optimizer Pro is a PC optimizer utility developed by Xportsoft Technologies. It is classified as a potentially unwanted program, due to its aggressive scan and registration reminders, and that it is often distributed bundled with other programs in a manner that leads many users to not know how it got on their computer. While not inherently malicious, PC Optimizer Pro adds numerous registry keys, startup entries and while running consumes a relatively high amount of system resources, especially during its scans. The software installs from a .exe file that is around 5.20 MB or 5.453.240 Bytes (depending on the version). As of the publication of these videos, the current version of PC Optimizer Pro was detected as malicious or potentially unwanted by at least 21 AntiViruses.

About Potentially Unwanted Applications

If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites. PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.

What do PUPs do on your computer, exactly?

Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl. Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.

Ways to avoid PUPs

• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging. • Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers. • Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs. • Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.

What you can do if Malware Prevents You From Downloading Or Installing Antivirus?

Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.

Install in Safe Mode

The Windows OS has a special mode known as “Safe Mode” in which just the bare minimum required programs and services are loaded. In the event the malware is blocking the internet connection and affecting the computer, running it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To start the computer into Safe Mode, press the “F8” key on your keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, look over “Safe Boot” under Boot tab, and click Apply. After you reboot into Safe Mode with Networking, you can download, install, and update anti-malware software from there. Right after installation, run the malware scanner to remove standard infections.

Switch to an alternate browser

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

Install and run anti-virus from the USB drive

Custom widgets in Windows 11 later
windows custom widgetsOriginally Microsoft has imagined its widgets menu as Microsoft-only widgets but it seems that they have changed their mind. Due to the latest leak, it seems that Microsoft will open the widgets menu to 3rd party developers as well but at launch, it will be only official widgets. It was hinted that later widgets menu will be open to developers who want to bring their own stuff into it. Distribution, date, and technology that will need to be used in order to create your widget have not been discussed nor leaked at a given time but in some way, I am very glad that at least some customization will be in Windows 11. It is funny and amusing how some things that were in Windows Vista are getting back like glass design, round corners, and widgets. Let’s just hope Windows 11 will be a better Windows than Vista was.
