Once that happens, choose the Fix/Repair button. Your scan will be completed. The error will be removed. You can then restart your computer again to ensure the error is no longer displayed.

Some other suggestions to keep your computer from encountering these problems in the future are outlined below.

• Update all your drivers. Obsolete or old hardware or software drivers may also trigger this STOP 0x000000D1 error.
• If you have recently installed or modified a driver or hardware and the error has occurred afterward, it is highly likely that the installation or modification has caused it. Revert back to the original settings to steer clear of this driver in the future.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

In case you don’t know, a teletype network, also known as Telnet, is a protocol that is meant for internet or LAN communication which is used primarily to control other computers effortlessly. And it is available as a command-line utility in Windows and helps users in opening a command-line interface for the remote computer. However, a lot of users have reported an error that states, “Telnet is not recognized as an internal or external command, operable program, or batch file” when you try to use it. If you are one of these users, then you’ve come to the right place as this post will guide you on how to fix this error in Windows 10. This kind of error means that the Telnet utility is not installed on your computer but Telnet is a default feature in Windows 10 so the protocol mainly is not enabled yet. The Telnet client is disabled by default in Windows 10 and to fix this error, you can try to enable the Telnet Client via Programs and Features or try to install Telnet using an elevated Command Prompt.

Option 1 – Try to enable the Telnet Client via Programs and Features

The first thing you can do is to enable the Telnet client using Programs and Features since it is disabled by default. To do that, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “appwiz.cpl” in the field and hit Enter to open the Programs and Features window.
• Next, select the “Turn Windows features on or off” from the options given on the left-hand side.
• After that, look for the Telnet client from the list and check the checkbox next to it and then click on OK to save the changes made.
• Now restart your computer.

Option 2 – Try to install Telnet via an elevated Command Prompt

If enabling the Telnet client using Programs and Features didn’t work, then you can try to do it using Command Prompt instead. To get started, follow the steps given below.

• In the Windows Search bar, type “command prompt” in the field and right-click on Command Prompt from the search results, and select the “Run as administrator” option.
• Next, execute this command to enable the Telnet client: dism /online /Enable-Feature /FeatureName:TelnetClient

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Try to run the System Restore in a Clean Boot State

If the first three given options didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run System Restore again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.

One of the important processes in the Windows operating system is the Setting Synchronization or SettingSyncHost.exe. This process is the one responsible for synchronizing the settings of your computer with other devices. It is the one that replicates settings like OneDrive, Internet Explorer, wallpapers, and so on, to other systems. However, it has been known to cause high CPU usage in Windows 10 and there are times when it causes the system to freeze or system lags. So if you notice that the SettingSyncHost.exe process is causing high CPU usage in your computer, worry not for this post will guide you in fixing them. You have to be cautious when you notice high CPU usages caused by system processes since cybercriminals mostly set the names of viruses in a way that the system or the user won’t be able to identify them. Cyber crooks could name the virus and malware the same as one of the system processes like SettingSyncHost.exe to make it seem like it’s a legitimate process. Thus, you need to keep in mind that original system processes like the SettingSyncHost.exe file are located in the System32 folder. The original SettingSyncHost.exe file is located in the System32 folder. To check for the same, right-click on the troublesome process in the Task Manager and select Open file location. If the place is any other than the System32 folder, run a full system anti-virus scan on the system. The SettingSyncHost.exe causes high CPU usage when it gets stuck in the sync process and is not able to come out of the loop. To fix this problem, you need to follow the solutions offered below but before you proceed, make sure that you create a System Restore point first.

Option 1 – Apply some registry tweak

The first thing you can do is to apply some tweaks to the Windows Registry. To get started, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERSoftwareMicrosoftInputPersonalizationTrainedDataStore
• From there, right-click on the key and select Permissions.
• After that, check the box next to “Allow” for Full Permission for every user group.
• Now click on the Apply and OK buttons to save the changes made.
• Then restart your computer.

Option 2 – Close the Host process for setting synchronization

If the registry tweak didn’t work, you can try to close the host process for setting synchronization, especially if this process continues to hog resources. You can terminate this process by opening the Task Manager. From there, end the process or task of the host process. On the other hand, you can also turn off the Host process for synchronization by opening Settings > Accounts > Sync settings located in the left pane. After that, turn off the Sync setting.

Option 3 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Performance Troubleshooter:

• Tap the Win + R keys to open the Run dialog box.
• Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Installing a Windows 10 upgrade is definitely not an easy task since the process is not always smooth sailing and you could encounter some errors when doing so. This isn’t unusual since there are various software configurations and hardware configurations as well as services it depends on in order to properly work. So if any of them malfunctions or becomes corrupted, it will affect the process which will result in errors like the error code 0x80300002. When you encounter this kind of Windows Update error, you will see the following error message on your screen:

“We couldn’t install Windows in the location you choose. Please check your media drive. Here’s more info about what happened: 0x80300002”

You can encounter this kind of error if there is corruption in the partition table of the drive where the installation is in progress. In addition, corruption on the Media device could also cause this problem. So if you encounter this error when running Windows Setup, read on as this post will guide you in fixing it. There are several ways to resolve this issue. The first thing you can do is to verify the compatibility between the BIOS and the installation media. You could also try recreating all the partitions as well as recreating the bootable USB drive. For more detailed information, follow the given options below.

Option 1 – Check if the BIOS is compatible with the installation media

The first thing you can do to fix the error is to check if there are any compatibility issues between the BIOS and the installation media you’re using. This is actually one of the most likely reasons why you’re getting the error since this is a complicated point for the Windows installation process. If the installation media is based on GPT, then your BIOS must be based on UEFI. So if you have your bootable media with the MBR partitioning, you need to set your BIOS to Legacy.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the “Legacy” option. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to Legacy and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Try recreating a new bootable drive

• Insert your USB drive into your PC.
• Tap the Win + R keys to open the Run dialog box and type in “cmd” and tap Enter to open the Command Prompt. Alternatively, you can also search for “cmd” in the Cortana search box to open Command Prompt.
• Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
• After that, you should see a new black and white window that would say, “DISKPART>”.
• Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
• Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
• Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
• Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
• A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
• Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick

Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.

• After that, type in this command and tap Enter after – active
• Finally, type this command and hit Enter to exit the utility – exit
• After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.

As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

USB storage devices, peripherals, and other devices are almost used on a daily basis. And as you know, when removing the USB storage devices, it is recommended to always use the “Safely remove the USB storage device” option in order to prevent data corruption in the USB storage device. However, there are times when you may see the following error message after you use the “Safely remove the USB storage device” option:

“Problem ejecting USB Mass Storage – This device is currently in use, close any programs or windows that might be using this device, and then try again.”

This kind of error message occurs when the device is still interacting with the operating system in the background. There are several ways you can fix this error but before you check them out below, you need to close all the open windows and programs that may be using the USB storage device and then wait for a couple of seconds and then try safely removing it again. However, if you are still getting the same error message, then here are some tips you should try:

Option 1 – Try to use the Task Manager

• Tap the Ctrl + Shift + Esc keys on your keyboard to open the Task Manager.
• After that, look for the running processes and programs hogging on your USB Storage device. The error could be due to a program or process that’s using the USB device. This program or process will hog onto some Disk or CPU while transferring data and interacting with the device.
• Once you find the culprits, right-click on each one of them and select End Process or End Task. You could also try to restart the process for “Explorer.exe” and see if it fixes the problem.

Option 2 – Try using DISKPART

The next thing you can try to resolve the issue is to use DISKPART. Refer to the given steps below to do so.

• Tap the Win + R keys to launch Run and then type “cmd” in the field and tap Enter or click OK to open an elevated Command Prompt.
• Next, type and enter this command to execute it: diskpart
• The command you entered will initiate the DISKPART utility. After that, type and enter this second command: list disk
• Next, type and enter this third command: list volume
• The commands you just executed will help you in either listing all the Disk connects or all the partitions on those disks formed and from there, you need to select one command depending on the “list” command you entered. You can execute either of the two following commands:
  • select disk #
  • select volume #

• After that, it will select the Disk or Partition you want to select.
• Now type either one of the following commands:
  • offline disk #offline volume #
• The command you entered will mark the selected disk is Offline. Afterward, try to safely remove your USB Storage device. Just remember that when you plug it back in again, you have to carry out the same method except for the last given command as this time you will have to enter either of these commands in order to get your USB storage device back online:
  • online disk #
  • online volume #

Option 3– Try using the Disk Management utility

• Tap the Win + R keys to open Run.
• Then type “diskmgmt.msc” in the field and hit Enter to open the Disk Management utility.
• Next, look for the entry for your USB Storage device and once you’ve found it, right-click on it and select Offline.
• After that, try to safely remove your USB Storage device again and see if the error is fixed. Note that you need to go over the same steps again if you want to plug your USB Storage device back in but make sure to select the Online option instead of Offline to get your device back online.
