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.

Error Code 0xd0000272 – What is it?

Error code 0xd0000272 occurs when Windows users are unable to activate their operating system. This usually occurs due to activation servers being busy or unavailable and affects Windows 8, Windows 8.1, and Windows 10 users. Common symptoms of the error code include the following:

• Inability to activate Windows operating system
• Message box with error code 0xd0000272

Solution

Error Causes

Windows users affected by error code 0xd0000272 usually receive a message stating that the “activation server is busy or unavailable”. Some users report the error is resolved on its own after a few hours, while others experience activation issues that resolve only after manual repair methods are implemented.

Further Information and Manual Repair

To improve your chances of resolving issues related to Windows activation error codes, use manual repair methods and procedures. These are often successful as they address the issues causing the error codes to occur, whether there be missing or corrupted system files, network connectivity issues, or invalid product keys.

Error code 0xd0000272 may be resolved by simply waiting until later – a few hours at most – to reattempt activation. If, however, the activation process fails, proceed with the methods suggested below or contact a Windows repair technician.

1. Method One: Verify Internet Connection to Activate Windows

Are network connectivity issues preventing your machine from activating Windows? Check for this issue by verifying whether or not you are connected. Once you’ve been able to check your connection via your Internet settings and troubleshoot your network where necessary, proceed to the Product Activation Wizard.

The Product Activation Wizard will check if you have permission or authorized access to the version of Windows you are attempting to activate. This process usually involves the use of a product key. Once you enter the 25-character code – in the correct order, of course – proceed by selecting the activation option.

If the process is successful, you will be able to complete the activation and access all the features of the Windows edition you have activated. You will also notice the absence of the error code 0xd0000272 message. In cases where this manual repair method is unable to successfully resolve the issue, however, move to the next manual repair procedure on this list.

2. Method Two: Run Windows Update Troubleshooter

Another tool available to Windows users is the Windows Update Troubleshooter. You may access the Windows Update Troubleshooter offered on Windows 8 since it does not require an internet connection and runs most of the functions required. To do so, follow the steps below.

• Step one: Swipe to the right of the screen and click Search
• Step two: Type Troubleshooting
• Step three: Click Settings then select Troubleshooting
• Step four: Under System & Security, click Fix Problems with Windows Update
• Step five: Select Next

You can also visit Microsoft’s website to access a more comprehensive Windows Update Troubleshoot tool. Download the troubleshooter and run it to fix problems related to Windows Update. Afterward, restart your computer then check the Product Activation Wizard to verify whether or not you can activate Windows 8 or 8.1.  If the problem persists, however, and error code 0xd0000272 reoccurs, proceed to the third manual repair method.

3. Method Three: Disable Proxy Settings

Your computer’s proxy settings may in some cases interfere with the activation process, resulting in issues like error code 0xd0000272. To fix this problem, first, disable your proxy setting then reattempt the activation process using the Product Activation Wizard.

• Step one: Press Win + C keyboard combination
• Step two: Select Settings
• Step three: Click Change PC Settings
• Step four: Select Network, then Proxy
• Step six: Switch proxy server settings to Off

Open the Product Activation Wizard once you’ve disabled the proxy settings. Complete the activation process based on the instructions provided. If you are successful, you will no longer be bothered by error code 0xd0000272 as the symptoms of the error code will not occur.

If, however, this manual repair method fails to resolve the error code, you may need to consider other alternatives. These may include the use of a powerful automated tool. You can also consider getting help from a Windows repair technician as such professionals are able to assess your computer and provide solutions as needed.

Error 1310 is a fairly common type of error encountered by Windows users. Error 1310 usually generates while a user is attempting to install Adobe Photoshop or some Adobe product on Windows. The message displayed to the user usually states: ‘Error 1310. Error writing to file. Verify you have access to that directory’. Once the error message appears, the installation process will be terminated.

Solution

Error Causes

While there are different conditions that may trigger this error, most likely, they are generated because of the lack of privileges a user has on a Windows log-on. When this happens, the operating system doesn’t allow the user to access the installation files. Another reason Error 1310 may occur is that often users attempt to log on to the system and choose the ‘Only for me’ option rather than the recommended ‘Anyone who uses this computer’. Because of this reason, the data is locked for all the other users. Since Error 1310 can easily disrupt your workflow on the system and may also lead to annoying consequences, it is best advised to treat it as quickly as possible.

Further Information and Manual Repair

There are different solutions to resolve these errors that are briefly listed below as follows.

• First and foremost, restart the installation by logging onto your computer from the administrator account. This error will most likely disappear because there is often a lack of privileges that will trigger it. When you will log on from the admin account, you will have access privileges and such errors will be rectified.
• Fix any corrupt system files that exist on your system. If the file resides in the Windows directory, this error will be generated. Check if any of your system files are corrupt or damaged. If yes, make sure you repair and return them back to their original position.
• This error is sometimes caused because of incorrect registry entries. If the setup program shows errors, it is possible that it is because the system is having problems retrieving data stored in the system registry.
• Another way, this error can be avoided is to run the setup in compatibility mode. Compatibility issues are a common occurrence. However, when an installation is performed in the compatibility mode, one can easily steer clear of such errors.

Implement any of the solutions listed above and protect your system against Error 1310.

If you are checking for an update on your Windows 10 PC and you got the error 0x80070005 due to some ACCESS DENIED permissions issue, then read on as this post will show you what you can do to fix the problem. For some reason, the Windows Update does not have enough rights or permissions to continue further which is why you’re getting an error instead. Thus, the first thing you can do before you troubleshoot further is to make sure that you’re logged in as admin. However, if you’re already logged in as one, then here are some suggestions that might help you fix the Windows Update Install Error 0x80070005.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 4 – Take control of the User App Data

There are times when permission to access the files is not configured correctly. As a result, it blocks the downloading of the updates. Thus, you have to take full control of the User App Data which is placed at C:/Users/USERNAME/AppData.

• First, go to C:/Users/USERNAME/AppData and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.

Kernel_Data_Inpage_Error - What is it?

Kernel_Data_Inpage_Error is a BSOD (blue screen of death) error. Also, know as a 0x0000007A Stop error. This bug check indicates that the requested page of kernel data from the paging file failed to be read into memory. In simple words, this means that Windows has trouble reading from the memory. This can apply to both kinds of memory: stored memory on your hard drive and also the dynamic memory in your RAM. The Kernel_Data_Inpage_Error turns your computer screen all blue, stops the program being executed, and sometimes even leads to abrupt system shut down.

Error Causes

Kernel_Data_Inpage_Error may occur due to numerous reasons. The exact cause of this error can easily be found by going through the code displayed in the parameter of 0x00000007A. Let’s take a look at Kernel_Data_Inpage_Error parameter codes and the underlying causes of its occurrence:

• 0xC0000009A- This parameter code triggers missing nonpaged pool resources
• 0xC0000009C- This represents the installed hard disk drive has bad sectors.
• 0xC0000000E- This indicates a hardware failure or an incorrect drive configuration

Further Information and Manual Repair

No matter what the cause for Kernel_Data_Inpage_Error may be, it is advisable to fix it immediately as blue screen of death error codes are considered to be critical PC errors that can cause serious damages and even result in valuable data loss. Here are a couple of ways to repair this issue on your system:

1. Call the ‘Chkdsk’ (check disk) command on your system.

Windows XP, Vista, and 7 users can call this command, by pressing Windows Key +F and type in ‘chkdsk’ and run. However, you can’t run it while actively using Windows but you can always schedule it to start automatically the next time your computer turns on. Wrap up what you need and then reboot. Chkdsk disk checking process can take a long time, especially on large and slow hard drives. To run this command on Windows 8, open Windows search by pressing Windows Key+ F and then type ‘cmd’. Then right-click on the command prompt and choose the option ‘Run as Administrator’. To continue with the disk checking process, here you will be prompted to provide your administrator authentication. Once you insert the administrator authentication, type the command ‘Chkdsk C:/f/r/x” where the letter ‘C’ indicates the drive you want to examine and repair. Run it to scan for Kernel_Data_Inpage_Errors on your system. Chkdsk command will detect and repair errors on the hard drive and then automatically reboot.

Limitations to this Solution:

‘Chkdsk’ is a value-adding inbuilt disk checking tool in PC new Window versions; nonetheless, this command has certain limitations. It is time-consuming. You may have to wait for a long time for it to scan your system. Also when disk check is running, you will have to stop all other activities on your system. Furthermore, Chkdsk does not scan and fix all registry errors and other PC-related errors. So, you can’t be 100% sure that it will resolve all the Kernel_Data_Inpage_Errors on your PC.
