Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

Here are the best ways to attempt to resolve Error Code 0x80070570 on your Windows device:

Method One:  Reattempt Installation

In some cases, when Error Code 0x80070570 appears on your computer, you can simply click on the OK button and then go back to the screen immediately proceeding where your installation has left off, choosing to restart the process of installation.

Method Two:  Check Your Various Sources of RAM

If you have more than one source of RAM in your computer, first remove one of the sources, then re-attempt installation. If you are still encountering Error Code 0x80070570 after removing one of the sources, continue to remove each until you are down to a single source, then trade that last source for one of the ones that have been pulled.

If you have a bad source of RAM, this can help you to figure out which input is causing the error to appear and to address the problem appropriately. Once you have determined which specific source is causing the problem, you can reboot your computer and attempt to run the installation process one more time.

If your RAM sources are not specifically causing the issue, you may still need to run diagnostics tests on your hardware to identify the source of the problem at hand.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

If you’ve tried resetting your Windows 10 computer using the Reset This PC option in order to restore your computer’s factory settings and the process suddenly fails for some reason and you got an error message instead stating, “There was a problem resetting your PC, No changes were made on your Windows 10 computer”, then this post might help you resolve the problem. Carefully follow each one of the options given below to resolve the “There was a problem resetting your PC error on Windows 10.

Option 1 – Try renaming the System and Software hive

• If you’re still able to boot to the desktop of your Windows 10 PC, open an elevated Command Prompt from the WinX menu.
• Now use the CD command and change the directory to Windows\System32\config folder. Simply type in the following command and hit Enter:

cd %windir%system32config

• After that, you have to rename the System and Software registry hives to “System.001” and “Software.001”, respectively. To do that, just type each one of the following commands and hit Enter after you type each of them.
  • ren system system.001
  • ren software software.001

On the other hand, if your Windows 10 PC isn’t able to boot to the desktop, you can just access Command Prompt from the Advanced Startup options or you can also boot into Sage Mode and open Command Prompt from there and then run the given commands above. Note: If you only want to use the Refresh your PC option, you must only rename System hive and not Software hive. On the other hand, if the Software hive is really corrupted, you might not be able to use the Refresh your PC option in such a case. Thus, you really need to rename the Software hive as well. Once you’ve renamed the Software hive, you won’t be able to use the Refresh your PC option but only the Reset your PC option.

• Type “exit” to close the Command Prompt and then restart your PC and try resetting your PC again.

Option 2 – Try to disable and re-enable the Windows Recovery Environment

If the first option didn’t help, you can try disabling the Windows Recovery Environment and then enable it back again. To configure a Windows Recovery Environment or Windows RE boot image and recovery options, you have to use the REAgentC.exe tool.

• Tap the Win + S key and type “REAgentC.exe” to open the REAgentC.exe tool.
• After that, type the following command and hit Enter to disable the Windows RE:

reagentc /disable

• After disabling the Windows RE, you need to enable it back by typing the following command:

reagentc /enable

Option 3 – Try to boot the USB recovery drive

If the two previous options failed, you need to try another workaround which is to boot to the USB recovery drive > Troubleshoot > Recover from a drive. From there, follow the on-screen instructions and you should be good to go.

Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.

Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:

Find and/or install the font that you wish to use

There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.

Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)

Create REG file

Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"="NEW-FONT"

All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".

Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG

Apply changes

Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.

Rolling back

If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"="segoeui.ttf"
"Segoe UI Black (TrueType)"="seguibl.ttf"
"Segoe UI Black Italic (TrueType)"="seguibli.ttf"
"Segoe UI Bold (TrueType)"="segoeuib.ttf"
"Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf"
"Segoe UI Emoji (TrueType)"="seguiemj.ttf"
"Segoe UI Historic (TrueType)"="seguihis.ttf"
"Segoe UI Italic (TrueType)"="segoeuii.ttf"
"Segoe UI Light (TrueType)"="segoeuil.ttf"
"Segoe UI Light Italic (TrueType)"="seguili.ttf"
"Segoe UI Semibold (TrueType)"="seguisb.ttf"
"Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf"
"Segoe UI Semilight (TrueType)"="segoeuisl.ttf"
"Segoe UI Semilight Italic (TrueType)"="seguisli.ttf"
"Segoe UI Symbol (TrueType)"="seguisym.ttf"
"Segoe MDL2 Assets (TrueType)"="segmdl2.ttf"
"Segoe Print (TrueType)"="segoepr.ttf"
"Segoe Print Bold (TrueType)"="segoeprb.ttf"
"Segoe Script (TrueType)"="segoesc.ttf"
"Segoe Script Bold (TrueType)"="segoescb.ttf"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"=-

There are times when you see a message in Windows Defender saying, “The Threat Services has stopped, Restart it now” when you try to use it. This kind of error is usually fixed by simply clicking on the Restart now button. However, if the error still appears even after you restart your computer and you see another message that says, “Unexpected error, Sorry, we ran into a problem”, then continue reading as this post will guide you in resolving this issue in Windows Defender. Before you proceed with the given fixes below, you have to create a System Restore point first. This way, you can always undo any changes you’ve made in case something goes wrong.

Option 1 – Make sure that the Windows Defender Services are started

The Windows Defender Advanced Threat Protection service is the one that protects your computer from advanced threats by monitoring and reporting security events that happen on your computer. This is why you have to make sure that this, as well as other required services in Windows Defender, are set to their default values and are started. To do so, follow these steps:

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager
• After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
  • Windows Defender Advanced Threat Protection Service – Manual
  • Windows Defender Antivirus Network Inspection Service – Manual
  • Windows Defender Antivirus Service – Manual
  • Windows Defender Firewall Service – Automatic
• You can right-click on each one of the listed services and then select Start to start them.
• And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
• Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
• Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try modifying some entries in the Windows Registry

If the first option didn’t work in fixing the problem, you can try to alter some entries in the Windows Registry using the Registry Editor.

• First, tap Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
• From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
• To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
• Afterward, set the value of the newly-created DWORDS to 0.
• Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.
