Fix Operating System Loader has no signature

Booting up your Windows 10 computer does not always go smoothly as it is a complex process and you may encounter some issues along the way. There are various files that get loaded and executed while the Windows 10 operating system is loaded. You might encounter a page that displays the following error message:

“Operating System Loader has no signature. Incompatible with SecureBoot. All bootable devices failed Secure Boot verification.”

There are two main causes for this error – it could be that your computer is using a bad unauthentic Boot Image File or the Windows operating system is installed in the BIOS Mode. To fix this error, you can try performing a “cold” boot or reset the BIOS or reset your Windows 10 computer.

Option 1 – Try to perform a Cold Boot

To perform a cold boot, all you have to do is press and hold the power button of your CPU until it goes off. Once it’s off, boot your computer normally and then check if the problem is now fixed.

Option 2 – Try resetting the BIOS

If performing a cold boot did nothing to fix the problem, you can try to reset the BIOS instead.

  • Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
  • Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
  • Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
  • Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 3 – Try to change the Boot Sequence

You could also try to change the Boot Sequence to fix the error. To change the Boot Sequence, follow these steps:

  • Open Windows Settings and then go to Update & Security > Recovery Advanced Startup and then click on Restart Now.
  • Once your computer has restarted, you should see the Advanced Options.
  • Next, select Troubleshoot > Advanced Options. This will offer another set of options and from there, select the UEFI Firmware Settings and it will let your restart your computer.
  • After the restart, it will take you to the Firmware settings and from there, switch to the Boot tab where you’ll see the “Boot Priority” which contains the list of the connected hard drive, CD/DVD, ROM, and USB drive.
  • Use the arrow keys on your keyboard to change the boot sequence.
  • Once you’re done, save and exit.

Option 4 – Reset your computer

  • Tap the Win key or click on the Start button located in the Taskbar.
  • Then click on the Power button at the bottom right portion of the screen.
  • Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen

  • Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

Fix Windows Update Error 0x8007001f – 0x20006
As you know, Microsoft’s Windows Media Creation Tool is a useful tool that helps you download and install the latest version of the Windows 10 operating system. However, there are times when it could encounter some problems during the update process. One of these programs is the following error message:
“0x8007001F-0x20006, The installation failed in the SAFE_OS phase with an error during REPLICATE_OC operation.”
The error pointed out the “Safe OS phase”. It is the phase that’s initiated to install all the required Windows Updates. Thus, the possible cause for this error could have something to do with an interrupted download, internet connection, and many more. Although this error could be caused by a lot of factors, fixing it shouldn’t be that hard. You can try to reset the Windows Update Components or delete the Windows Update cache. You could also disable both the Firewall and your antivirus program temporarily or run the Windows Update in a Clean Boot state, as well as run the Windows Update troubleshooter. To get started troubleshooting the error, follow each one of the suggestions provided below.

Option 1 – Try to reset the Windows Update components

Resetting the Windows Update components could help you resolve the Windows Update error 0x8007001f – 0x20006. How? Refer to the following steps:
  • Open Command Prompt with admin privileges.
  • After that, type each one of the following commands and hit Enter after you key in one after the other.
    • net stop wuauserv
    • net stop cryptsvc
    • net stop bits
    • net stop msiserver
Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.
  • After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
    • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
    • ren C:WindowsSystem32catroot2 Catroot2.old
  • Now, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
    • net start wuauserv
    • net start cryptsvc
    • net start bits
    • net start msiserver
  • Exit Command Prompt and then restart your computer.

Option 2 – Try to delete the Windows Update Cache

You might also want to delete the Windows Update cache since there are times when existing corrupt or incomplete Windows Update files can cause some problems in downloading and installing Windows Updates. To achieve this, simply delete the “$Windows.~BT” & “$Windows.~WS” folders in your computer. Once you’re done, try to run Windows Update again and see if the error is now fixed.

Option 3 – Try to temporarily disable anti-virus and Windows Defender Firewall

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like error 0x8007001f – 0x20006 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not

Option 4 – Run the Windows Update in a Clean Boot State

It is possible that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.
  • 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 the “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 configure Windows to use the usual startup, just simply undo the changes.)
  • After that, try to run Windows Update again.
Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application on your computer. You need to look for the culprit and uninstall it once you found it.

Option 5 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing error 0x8007001f – 0x20006. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

How to Use and Configure Active Hours
The issue with the abrupt system reboots to force Windows 10 updates on a computer has been lessened with Active Hours. This feature keeps a record of the hours during which a system remains active and prevents the installation of updates during such hours. For example, when a system restart is needed to complete the installation of an update, Active Hours delays the update and allows you to finish what you’re doing on your computer. Thus, if you haven’t heard of this feature, then now is the time you do, read this post to configure and use Active Hours in your Windows 10 computer. There are three ways you can configure Active Hours. The first one is for general users, whereas the rest of the two methods are for users who knows their way about the Windows Registry and Group Policy. To get started, refer to every given option below.

Option 1 – Configure Active Hours via Windows 10 Settings

  • Go to Settings > Update & Security. From there, click on the “Change active hours” option under the Windows Update section.
  • Next, you can select a time (“Start time” and “End time”) during which the restart can occur.
  • After that, click on the Save button and exit.
Note: Keep in mind that the values you’ve entered indicate the hours during which your system is in use, namely, ACTIVE. It is important for your active hour’s interval period and it can be anything between 1 and 18 hours since you can’t go beyond 18 hours. In addition, there is no option to configure different active hours on different days and you can’t specify different active hours for weekends and weekdays as well. On the other hand, Windows 10 also offer users an option to override Active Hours. All you have to do is go to Settings > Update & Security > Windows Update > Restart Options. From there, you can choose a custom restart time when your computer will restart to install the updates but this is only a one-time setting.

Option 2 – Configure Active Hours via Registry Editor

  • Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter or click OK to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsUpdateUXSettings
  • In the given registry path, you can choose to change “ActiveHoursStart” and “ActiveHoursEnd”.
Note: There are no extra settings available in the Registry Editor but you can change the remote computer’s Active hours settings using the Registry Editor.

Option 3 – Configure Active Hours via Group Policy

Note that this option is available for the Windows 10 Pro and Educational or Enterprise versions. It is mostly used by computers in Business or through remote access. To get started, follow these steps:
  • Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and tap Enter or click OK to open the Group Policy Editor.
  • Next, navigate to this group policy setting: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Updates.
  • From there, look for a policy labeled “Turn off auto-restart for updates during active hours” and double click on it. This will open a new window.
  • Click on the Enabled radio button to enable Active Hours. You also have the option to choose active hours just like in the first given option above. It works just fine except when the following policies don’t override:
    • No Auto-restart with logged-on users for scheduled automatic updates installations.
    • Always automatically restart at the scheduled time.
  • Since Group Policy allows you to reduce the range of active hours, you can configure it if you want it to be less than 18 hours. Just find the policy setting labeled “Specify Active hours range for auto -restarts. The minimum is 8 hours”.
  • After you set the Active Hours, click the Apply and OK buttons to save the changes made.

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.


Credit: FLY:D on Unsplash

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.

Fix Out of Memory error while copying files
What is Out of Memory error while copying files? As you know, both the hard drive and RAM play a major role in performing any operation on a computer since every process or task that takes place in the system requires some RAM storage as well as hard drive storage to be executed. However, there are times when you may receive the following error messages when you try to copy files from one location to another:
“Out of memory or system resources, Close some windows or programs and try again.” “There is not enough memory to complete this operation – copying files.”
These errors are caused by the Desktop Heap limitation when there is no longer enough memory to complete the operation while copying the files. If you encounter any of these errors, you will be guided in this post with the help of some potential fixes that can increase its limit and will hopefully fix this error on your Windows 10 computer. You may try to close all the open windows and programs and then try copying the file again and see if that helps. If not, then proceed to the instructions given below. But before you do that, make sure that you create a System Restore point first. This way, you can undo the changes you’ve made any time in case there are some unwanted changes you want to reverse. After you create a System Restore point, refer to the steps provided below. Step 1: Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor. Step 2: Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems Step 3: Now double click on the DWORD named Windows to modify it. Step 4: Change the values for SharedSection in the Value Data field. It should be in the format of “SharedSection=aaaa,bbbb,cccc”. Note that you have to change the value of “bbbb” and “cccc”. So in case you are using an x86 operating system, set the value of bbbb to 12288 and then set the value for cccc to 1024. On the other hand, if you are using an x64 operating system, set the bbbb value to 20480 and the cccc value to 1024. Step 5: Exit the Registry Editor and restart your computer to successfully apply the changes made. Note: The bbbb value in the SharedSection registry is the size of the desktop heap for each interactive window station while the cccc section of the SharedSection value is the size of the desktop heap for each non-interactive window station. In addition, you must keep in mind that setting the value of bbbb to more than 20480 KB is not really recommended. On the other hand, there is another tool that could help in resolving the Out of Memory error. This tool is called the Memory Diagnostic tool in windows can help resolve the Out of Memory error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:
  • Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.

Fixing “The .NET Framework 4.7 is not supported on this operating system” Error in Windows 10
In case you don’t know, the .Net Framework is a programming infrastructure introduced by Microsoft. You will need it to run on lots of services and applications. Note that most of the applications that require the .Net Framework are packed with their installation files which is why it will be installed automatically on your computer when you install an application. However, there are instances when you’ll get an error message saying, “The .NET Framework 4.7 is not supported on this operating system” while trying to install the .NET Framework as a standalone service. The very reason why this error message appears is stated in the error message itself. Although the .Net Framework is supported on Windows 10, it is not actually compatible with some other Windows 10 versions. So it is most likely that you are seeing this error message because the .Net Framework in your computer is not compatible with the Windows 10 version you are running. Since that’s the case, you need to update Windows 10 to fix the problem. Updating your Windows 10 computer is the only solution you can try to fix this problem. Thus, it is advised that you check for Windows Updates even if you are now using the latest version of Windows 10. And since the issue is caused by an incompatible operating system version, once you install the exact version of Windows 10 required by the .Net Framework, the problem will be fixed. Simply follow the steps given below to do so.
  • Step 1: Tap the Win + R keys to open the Run dialog box.
  • Step 2: After that, type in “winver” in the field and tap Enter.
  • Step 3: Next, your Windows 10 version should be given in the new window that appears. Take note that the number after the Version which is in the second line is your version number of Windows 10. And that the number must be 1507 or 1709. The first two digits in these numbers are the year while the second two represent the month when the update was released. So if you are running a 1709 version, this means that the Windows 10 version you are using was released in September 2017.
  • Step 4: The next thing you have to do is to make sure that you have the Windows 10 version that’s compatible with the .Net Framework. To verify, you need to click here and click on the System Requirements.
After opening the link, take a look at the Supported Operating System section where it says, “Windows 10 Anniversary Update” and “Windows 10 Creators Update”. Since there are users who are not familiar with the version numbers related to both the Anniversary and Creators updates, refer to the list given below.
  • November Update (1511)
  • Anniversary Update (14393)
  • Creators Update (1703)
  • Fall Creators Update (1709)
  • Spring Creators Update (1803)
As you can see, the Creators Update has version 1703 while the Anniversary Update has version number 14393 so if you are using a version lower than the 14393 version then it’s no wonder you aren’t able to install the .Net Framework 4.7 on your Windows 10 PC. Now all that’s left to do is to update your Windows 10 version and make sure that you will be updating it to the latest version available and then try installing the .Net Framework again.
