Repair Windows 10 Error Code 0xC1900200, 0x20008

Error Code 0x80070070 - What is it?

Error code 0x80070070 can be presented when there is not enough drive space on the computer to install updates. It is possible to uninstall apps that are not often used, or you may delete or archive files that are no longer needed, you may even add on some removable storage space to free up the internal memory of the computer. The computer needs a significant amount of internal memory in order to be able to update the operating system properly. When the computer fails to have the amount of memory that is needed to perform the update, the error code 0x80070070 will be presented. If this error message is not resolved, your computer might be opened to other error messages, including error code 0x80072EE2.

Common symptoms include:

• Windows cannot install updates properly.
• You might not be able to install any additional programs or apps onto the computer.
• When you check the memory of the computer, it may be very near its full capacity.

Solution

Error Causes

The Windows 10 upgrade error is caused by varying factors including a lack of computer space or resources, malware or virus infestation, or a clogged registry on the computer.  The error code 0x80070070 will present itself when there is not enough free space on the computer to perform the necessary updates on the computer. Too many apps or programs downloaded onto the computer, too many photos, or too much music may also contribute to the lack of storage space on the computer, thus contributing to the error, and the computer not being able to install the updates to the operating system properly.

Further Information and Manual Repair

There is not a lot of information regarding this error code, but there are a few methods to repair it when it does present itself. There are practical and manual steps that can be taken when trying to get the PC up and running. The primary way to solve this problem is to free up disk space and there are several ways to do this. Please do note that if these methods seem confusing or too complicated, do contact a Windows repair technician so that they may properly correct the problem. You will need to know for sure that it is error code 0x80070070 that you are dealing with so that these options are the best bet for fixing it.

Method One: Disk Cleanup

It is important to know how much space there is on the computer to start with prior to trying to free up any space. Use the free program on the computer called the Disk Cleanup tool. This will save time and free up some hard drive space while optimizing the computer to work better.

From the Start menu, browse to the Explore option, and then select This PC. Right-click on the C drive, and then select Properties. Select Disk cleanup. From here, select the options that you would like to clear. Make sure that the recycle bin is emptied of any temporary files or any error logs. Once done, select Okay.

Use this same process to clear the system files after an update from Windows, as they may still have files from the old operating system in place.

Method Two: Remove Unwanted Apps

Go through your computer and remove any unwanted apps that are present. There are sure to be some that you do not use or do not want.

Follow these steps: From the Start menu, select Settings. Then, select System, Apps, and Features. When you have found the program that you would like to uninstall, select it and then select Uninstall. NOTE: some apps that are built into Windows do not have the capability to be uninstalled. Once you have selected Uninstall for the app or program, follow all directions that appear on the screen.

Method Three: Cloud Storage

If there are a lot of media, photos, documents, videos, and the like that are not used on a regular basis, try out cloud storage. These files will still be in your possession and will be able to be accessed from anywhere. There are many applications or websites that cater to this.

Method Four: External Storage Options

If none of the above methods work, add more storage. To acquire more storage, you can incorporate devices such as SD cards, USB flash drives, and even external hard drives.

Method Five: 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.

Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program. Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build. I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens. Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements. So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.

Recently Logitech has released a new line of ergonomic mouse products on market, strangely shaped and lifted on a vertical axis Logitech claims that these devices will fix your issues and ease your hand pains for prolonged use of the computer.

The first time I saw this mouse I was not really impressed with its looks and somehow I thought it will not feel good. This all changed when I actually started using it, surprisingly altho strange in looks it does feel much more natural and much less stressful on hand. Also, it felt like I have used it before, personally, I did not need any adjustment period in order to use it fully.

All of that being said I will admit that using it for gaming is still not an option for me, someone might find it ok, especially if they play some games that do not need to be responsive like strategies or similar but for RTS and FPS I will still stick to the typically shaped mouse. This might be just a habit for me but somehow I feel more responsive with the typical mouse, but for anything else, this is the mouse that will keep your hands stress-free.

Now in order to get the mouse to be really recommended it needs to have some good technical specifications as well, looks are not all. The less important detail is that the mouse comes in 3 different colors: Black, white and pink, and its technical specifications are:

Specs & Details

Dimensions

Height: 71 mmWidth: 70 mmDepth: 108 mmWeight: 125 g

Personally, I would recommend this mouse for anyone who does work in front of the computer during the whole workday since it really does loosen grip and strain on hands.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

If you are trying to install a Windows 10 upgrade but was interrupted with an error saying, “0x80070003 – 0x2000D, The installation failed in the SAFE_OS phase with an error during MIGRATE_DATA operation”, then you’ve come to the right place as this post will help you sort this problem out. When you get this kind of error while trying to upgrade your computer, although there could be various reasons for this, the primary one is that when you upgrade from one update to another, something stopped the upgrade process to migrate the user data. To fix this error, you can try to run both the DISM tool and the System File Checker to automatically repair any corrupted system files. You could also try checking the free storage space of your primary drive and if you have any file lock apps like BitLocker, consider disabling them for they could also be the reason why you’re getting the error.

Option 1 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10 which might be the reason behind the Windows Upgrade error 0x80070003 – 0x2000D. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Once it’s done, restart your computer and then check if the issue is resolved or not on the next startup.

Option 2 – Run the SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Upgrade error to appear. 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 to 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.

• Reboot your PC.

Option 3 – Try checking the free storage space on your primary drive

The next option you can try to resolve the error is to see if you have enough free storage space on the primary drive because if you don’t then it’s probably the reason why you’re getting this error. To fix it, you need to free up some storage space by following these steps:

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• System created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Try disabling BitLocker and other file lock apps

If you are using BitLocker or other file lock apps, then it could be the reason why you’re getting the error. Usually, file lock apps don’t cause any kind of issue, however, if you have something that works on file level like BitLocker, you can try to disable it. Once you’ve disabled it, try to install the Windows 10 Upgrade again and after you do, enable BitLocker again. This should fix the problem.

The Recycle Bin is undeniably an important place to make files ready for deletion. To put it simply, it assumes some importance but there are times when it displays an unpredictable behavior. For instance, it just suddenly goes missing and even Cortana is unable to find it. A lot of users have experienced the missing Recycle Bin issue in their Windows 10 computers. If you are one of these users, you might have wondered where the Recycle Bin icon has gone and how you can get it back. Worry not, as this post will provide you a couple of options you can try to bring back Recycle Bin in your Windows 10 computer. Follow the given options below to get started.

Option 1 – Try to restore Recycle Bin

It could be that you have disabled the Recycle Bin by accident which is why Windows was not able to show it on your desktop. To restore Recycle Bin, follow these steps:

• First, click on the Start button and select Settings.
• Next, select the Personalization setting and then select Themes from the left pane.
• After that, click on the “Desktop icon settings” link under the “Related Settings” heading. This will display a list of icons in the Desktop Icons window.
• From there, make sure that you check the checkbox for “Recycle Bin” to make it appear on your Desktop screen once again.

Option 2 – Try to recreate the Recycle Bin

If the first option didn’t work, then it could be that Recycle Bin might have been deleted which is why you fail to restore it. And to resolve this problem, you need to recreate Recycle Bin. Refer to the following steps to do so:

• You need to launch the Windows File Explorer first and go to the View tab.
• From this tab, select Options and click on the drop-down arrow and then select the “Change folder and search option”.
• Afterward, switch to the View tab when the Folder Options window appears on your screen and select the “Show hidden files, folders, and drives” option.
• And then unmark the checkbox next to the “Hide protected operating system files (Recommended)” option and click on both the Apply and OK buttons, respectively.
• Next, go back to the File Explorer and click on “This PC” located on the left bar and go to the C: drive.
• From there, you will find a file named “$Recycle.Bin” located at the top.
• Open this folder to access its contents and you should see the Recycle Bin icon located at the top.
• After that, right-click on the Recycle Bin icon and click on the “Send To” option and then click on “Desktop (create shortcut)”.
• It will then confirm and recreate the Recycle Bin icon on your Desktop screen.

Note: Even though this icon is quite similar to the original one, it actually differs from it. The difference is that you won’t see if fill up when you delete files and you can’t simply empty it by right-clicking on the shortcut. On the other hand, you can still drag items into it just like with the original one. So when you want to empty the content of the newly restored Recycle Bin, you just have to double-click on the shortcut and right-click on the recycle bin in the window that appears, and select the “Empty Recycle Bin” option. In addition, now that you’ve set up the Recycle Bin shortcut, you have to re-activate the “Hide protected operating system files” to keep the important files and folders in your computer hidden.

Option 3 – Try to repair the Recycle Bin

If both the first two options failed to restore the missing Recycle Bin, then you can try repairing it instead. There are times when the Recycle Bin is removed from the Desktop screen due to some corrupted Windows system files. To fix these corrupted system files, you can run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the missing Recycle Bin. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the problem is now fixed.

Option 4 – Make sure that you are not in Tablet Mode

Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Recycle Bin. To check if your computer is really in Tablet Mode, follow these steps:

• Go to the Start menu and select Settings.
• Next, select the System setting and from the left pane select the Tablet Mode.
• From there, make sure that the buttons next to the options given below are set to the off position:
  • Hide app icons on the taskbar in tablet mode
  • Automatically hide the taskbar in tablet mode

If you are typing inside the Search bar, Cortana, Taskbar, Windows 10 apps, etc., and then everything seems invisible then read on as this post will guide you in fixing this issue. At first, you might think that something is wrong with your keyboard but it really has nothing to do with it. The problem actually lies with the apps from Microsoft Store. Thus, if you can’t type anything in any of the apps from Microsoft Store in Windows 10, refer to the options given below to fix them.

Option 1 – Ensure that ctfmon.exe is running

Ctfmon.exe is a Microsoft process in Windows 10 that controls the Alternative User Input as well as the Office Language bar. In other words, it enables end-users to control the computer using on-screen keyboard inputs, speech, and even pen for various languages. It would be better if you launch the program once by going to the C:/Windows/system32 folder. Doing so will ensure that whatever API is needed for the keyboard typing to work properly again. You also have to make sure that its startup status is not disabled. In addition, you can also try the following steps, alternatively.

• Open the Task Scheduler.
• Then go to Microsoft > Windows > TextServicesFramework.
• And on the MsCtfMonitor, right-click and enable the task.
• Now restart your computer.

This will ensure that all the text boxes will start to work again. And if the task MsCtfMonitor is missing from the list of tasks, you can import it with the XML file from basics.net. Then download and create a task to run it each time you log in to your PC.

Option 2 – Use the Windows Store Apps Troubleshooter

You might also try running the Windows Store Apps Troubleshooter as it can help in resolving issues with the Windows Store apps. This built-in tool can resolve most of the app-related problems. To use it, go to Settings > Update & Security > Troubleshooting > Windows Store Apps and from there, click the start the troubleshooter button. The Windows Store Apps Troubleshooter will scan the computer for any issues with the Windows store apps and will automatically fix them if it finds any.

Option 3 – Re-register all the Windows 10 UWP apps using PowerShell

• First, make sure to close all the running applications on your computer.
• Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
• After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
  • reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
  • get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
  • $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
  • get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the problem.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the System File Checker Scan

System File Checker or 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 to 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

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.

• Restart your PC.

As you know, each one of the Windows 10 versions is priced differently and one of the considered more expensive compared to the Windows 10 Home version is the Windows10 Pro. The good thing is, Microsoft allows its users to upgrade from the Windows 10 Home version to the Windows 10 Pro version at a reasonable cost instead of buying the entire license again. However, upgrading your Windows 10 computer is not always that easy and you might encounter some errors along the way. One of the reported errors you could encounter is an error message that says, “Something happened, and we couldn’t start the upgrade”. This kind of problem is due to the problems with the Microsoft Store or the key authorization and to fix it, there are several options you can check out. You can try to run the built-in troubleshooters such as the Windows Update troubleshooter, Windows Store Apps troubleshooter, or Microsoft Accounts troubleshooter. You could also try to reset the Windows Store cache or re-register the Windows Store app. For more details, refer to each one of the given options below.

Option 1 – Try to run the Microsoft Accounts troubleshooter

Since the Microsoft Accounts troubleshooter is not built-in into the Windows operating system, you can download this troubleshooter by clicking on this link.

Option 2 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the “Something happened, and we couldn’t start the upgrade” error. 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.

Option 3 – Run the Windows Store App troubleshooter

The Windows 10 Store Apps Troubleshooter will help you in fixing the problem in Microsoft Store. This is a great built-in tool from Microsoft that helps users fix any app issues. To use the Windows Store Apps Troubleshooter, follow the steps below.

• Tap Win + I keys again to open the Windows Settings panel.
• Go to Update & Security and then go to Troubleshoot.
• Under the Troubleshoot section, on your left-hand side, scroll down to find Window Store Apps.
• Then click on the Run the troubleshooter option and follow the on-screen instructions and then see if it fixes the problem.

Option 4 – Try to reset the Microsoft Store cache

As you know, like any other apps, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again and then try to install your app or update your computer again.

Option 5 – Try to re-register the Microsoft Store app via Windows PowerShell

• Tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
• Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRootWinStoreAppxManifest.xml

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

Option 6 – Try contacting Microsoft

If none of the options worked, you might also want to contact Microsoft for further assistance in fixing the error.

The Windows 10 Telemetry and Data Collection features are auto-enabled and they collect all sorts of user activity and sends it to Microsoft. Microsoft says that the data collected only enhances the overall user experience and Windows functionality better but the number of data breaches happening across the globe has forced users to be extra cautious about their data privacy. So naturally, from stronger passwords and other services management, it is only logical to turn off Windows data gathering. To do so:

• Press ⊞ WINDOWS + R to open the run dialog.
• In the Run dialog type: taskschd.msc
• Press CTRL + SHIFT + ENTER key combo to open Task Scheduler in admin mode.
• On the left pane, navigate to the: Task Scheduler Library > Microsoft > Windows > Customer Experience Improvement Program
• At the location, on the middle pane, right-click on the task named Consolidator and select Disable from the context menu...
• Repeat the process with all other tasks listed in the middle pane.
• Exit Task Scheduler.

Hello and welcome to How To Speed Up PC Startup where we will explore how to make your PC boot-up system faster. When your computer gets older, you'll see a decrease in your PC's load time. This can be very annoying and frustrating, especially if you're not accustomed to exercising patience. Your computer's boot time does not need to be sluggish, even if it's old. While there are reasons why your computer is acting up and giving you the 'slow' sign, there are ways that you can optimize how fast your PC starts up at the beginning. Once you start speeding things up, you’ll never look back!

Start With your BIOS

You may need to tweak your PC’s start-up menu. Since the majority of issues encountered on your PC might not be related to the software running in the back end, you can focus on your computer's hardware. The ideal way to speed up your PC startup is to access your computer's BIOS when booting up. This can be accessed by holding the DEL key or whichever button is used to tap into your BIOS. You can change where your computer boots from. You can opt to put your hard disk right at the top which would elude searching for CDs and other storage media devices when your PC starts up.

Tweak Startup Programs

There are many programs that execute when your computer starts up. These programs normally run in the back end. Most times back-end programs are unnecessary and do not contribute to the productivity or performance of your computer when in use. Instead of allowing these programs to execute when your PC boots up, why not disable them?  By deactivating these programs, you'll be reducing the amount of CPU usage which will accelerate your PC performance. Additionally, there are some installed programs that you never use. Instead of leaving these programs to occupy needed space on your computer system, you can uninstall these to create more room on your computer. This actually increases your PC startup speed.

Put Malware on a Leash

Malware and spyware can cause problems for your start-up. A slow computer is an indication that your computer is plagued by malware. This affects your computer's boot time and whether or not it'll startup as quickly as you intend it to. If your computer gives you the 'virus alert', you need to download an antivirus program that will be able to eradicate all virus threats. Be mindful of where you download antivirus programs since many of them are viruses or have viruses attached to them. Some viruses are tough on your computer. This means that if an antivirus works for your best friend, it may not work for you. Since malware differs in functions and the havoc they cause, it's best to know what you're up against by doing research.

Clean Your Registry

You should also clean out your registry. The fewer unused registry keys you have lying around on your computer, the faster your computer will go. Getting a good registry cleaner from a clean source can help tremendously, but be careful; registry cleaners have the potential to be very dangerous so make sure you backup everything on your computer and only download registry cleaners from a reliable source. By implementing the above tips, you'll see quick improvements when using your computer.
