Shift Key is not working in Windows

What is this particular error?

One common issue when trying to upgrade to Windows 10 from Windows 7 or 8 is incompatible software. Any installed software or app that isn’t compatible with Windows 10 will prevent you from continuing with the set-up. Normally, you’ll get an error message “What needs your attention” and it will ask you to uninstall a list of apps manually. Unfortunately, some users reported that they couldn’t find the app it asks to uninstall. In some cases, users said they’ve already uninstalled the app but it still won’t start the Windows 10 Setup.

Solution

Error Causes

This type of issue normally occurs because of the following:

• Incompatible software/apps
• Corrupted software/apps
• Incomplete uninstallation

Further Information and Manual Repair

Here are some steps you can take whenever you encounter this error.

Note: Before taking any steps, make sure that you’re highly equipped to do so. Some steps might affect the system and even do more damage to your computer. You might also want to consider using an automated tool instead.

Method 1 – Perform a clean boot, then retry upgrading

A clean boot is normally done to start Windows using the least set of drivers and startup programs available. By doing this, it eliminates possible software issues that happen when installing or uninstalling a program in Windows 10.

Before performing a clean boot, make sure to take note of the following:

• You need administrative privileges in order to perform this action.
• When doing this, your computer might lose temporarily functionality. However, it will return after start-up.
• It is highly advisable to not use the System Configuration to change advanced boot options.

Here are the steps to perform a clean boot.

• Step 1 – Go to Start and search for msconfig
• Step 2 – Go to System Configuration
• Step 3 – Under Services tab, click on the “Hide all Microsoft services” checkbox. Then, choose to Disable all
• Step 4 – Go to the System Configuration’s Startup tab. Then, click on “Open Task Manager”
• Step 5 – In the Task Manager dialog box, you will see a Startup tab. Choose items that you want to disable and then click the Disable button
• Step 6 – Close the Task Manager dialog box.
• Step 7 – Go back to the Startup tab of the System Configuration box. Click “Ok” then proceed with restarting.

Method 2 – Manually uninstall programs from the Program Files folders

Instead of using the “add or remove programs” feature in Windows, you might need to manually install the program directly from the C drive. To do this, follow the steps below:

• Step 1 – Go to the C drive, and look for the Program Files folders. For 32-bit users, you can find it at C:\Program Files. If you’re using the 64-bit version of Windows, go to C:\Program Files (x86) folder.
• Step 2 – Find the “uninstall” application file
• Step 3 – Right-click, and run the file as administrator. Wait for the uninstallation to finish. In some software, you need to restart your system before the uninstallation will take effect.

Note: In some cases, you may also need to search for files related to the program. You can use the search bar under Drive C to do this. Delete those files as well.

Method 3 – Create a new user account

Before upgrading to Windows 10, create a new user account. Make sure it has administrative privileges. From there, run the upgrade.

Method 4 – Use third-party uninstaller services

If you still can’t run Windows 10 Setup after the above methods, you might need to rely on a third-party service. Microsoft recommends Revouninstaller that can help you.

Before using this software, reinstall the application or utility that Windows 10 wants you to install. Then, use Revouninstaller to delete the program completely.

Method 5 – Disable third-party antivirus software

Some users who experienced this issue reported that it was solved after disabling or completely uninstalling the anti-virus software installed in their system.

Method 6 – Use a trusted automated tool

If after trying the above methods, the problem still persists, it might be best to use a trusted automated tool to fix the issue.

Error 451 - What is it?

This is a typical SMTP error code. SMTP is the abbreviation for Simple Mail Transfer Protocol. It is an internet standard for email transmission. In other words, SMTP is a text-based protocol in which the sender communicates with the mail receiver by issuing commands and receiving a response code. The SMTP error 451 is displayed in the following format:

‘451 Requested action aborted: local error in processing’

This error message indicates that the program cannot send more messages and the server has hit the limit. This is because some mail servers have limits. The sever stops the task of sending and receiving emails when this limit is achieved.

Solution

Error Causes

The causes of error 451 include:

• Server limit reached
• Email rejection due to a remote anti-spam filter
• Request denied by the server
• Viral infection

If you heavily rely on email communication with your business partners and colleagues, then it is advisable to immediately resolve this issue without any delays. Though this error is not fatal, you should repair it right away to avoid inconvenience. SMTP error code 451 can hamper your ability to communicate via email.

Option 3 – Try creating a new user account

Creating a new user account can resolve the “Some apps need to be uninstalled” error when upgrading or updating your Windows 10 PC. All you have to do is create a new admin account and initiate the setup. And this is a new user account, there will be no third-party applications installed on your computer. Thus, the installation should go through without any trouble. And in case you’ve already installed programs for that user, you just have to uninstall them all and then re-run the setup.

Option 4 – Perform a clean install

If none of the options worked, you can try to clean install Windows 10. Just make sure that you have the ISO from the official Microsoft Website and then a bootable USB drive to install Windows 10 again. Take note that this will delete all the data from your drive where Windows 10 was installed previously.

There are instances when you might encounter an error that says, “Something went wrong, We couldn’t start your program” when you open any Office program. This could be due to an issue with the Office file and any Office app you open throws the same error message. This applies to Office 2019/2016, Office 365 Home, Office for Business as well as Business editions. In this post, you will be guided in what you can do to resolve this error. There are several potential fixes for this error, you might only have to restart your computer or you may have to repair Office from Apps and Features or you could also uninstall and install it back again. For more details, follow each one of the provided options below.

Option 1 – Restart your computer

You might be unable to launch any Office app due to some background process that got stuck or there might be some glitch in the system. Thus, the first thing you can do to resolve the error is simply restarting your computer. Once you’ve restarted your computer, open the Office app again or you could also try to sign in back with your Microsoft account that’s connected to Office. If you’re not quite sure which account you were using, you can follow these steps:

• Open any Office app.
• Then click on File and look for your name located in the top-right portion.
• Now click on it. This will display the email or Microsoft account that’s related to Office.

Option 2 – Try repairing Office from Apps and Features

Note: When you choose to repair, you might be given two options which depend on how Microsoft Office was installed. For instance, it was installed via Web Installer or Offline Installer (MSI-based). In Web Installer, select Online Repair > Repair when you’re prompted on how you would like to repair Office. While in MSI-based, you have to select Repair under “Change your installation” and then click on Continue. The repair process makes sure that the app data remains untouched.

Option 3 – Try to uninstall and reinstall Office

If neither of the two given options above worked, then you might want to uninstall Office and reinstall it. All you have to do is download the Microsoft Office Uninstall tool from the official site of Microsoft and run it. This will remove any incomplete Office installation as well as unwanted files. It will also get rid of all the Office apps and settings on your computer.

As you already know, the Windows Update mechanism in Windows 10 is a bit complex as it depends on thousands of files and services in order to properly function. There are DLL files and services that support this mechanism’s proper functioning. And so if there is any malfunction with any of these files or services, it will result in some errors when running Windows Update. One of these errors is the error code 0x8e5e0147 which has the following error message: “There was a problem installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help – Error 0x8e5e0147” To fix this error, there are several methods you can try. You can run the Windows Update troubleshooter or reset the Windows Update components manually or clear the SoftwareDistribution folder and install the update manually. You could also reset the Windows Update Agent to default using a command in PowerShell.

Option 1 – Try to run the Windows Update troubleshooter

The first thing you can do to fix the Windows Update error code 0x8e5e0147 is to run the Windows Update Troubleshooter. 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 2 – Try to reset the Windows Update components

If by any chance that the third option didn’t work, you can also try resetting the Windows Update components as it could also help you resolve the Windows Update error. How? Refer to the following steps:

• Open Command Prompt with admin privileges.

  • 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:/Windows/SoftwareDistribution/SoftwareDistribution.old
  • ren C:/Windows/System32/catroot2/Catroot2.old
• Next, 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
• Close Command Prompt and reboot your PC.

Option 3 – Try downloading and installing the Windows Updates manually

Windows Update error code 0x8e5e0147 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes. Option 4 – Try to reset the Windows Update Agent Since you can’t update the Windows Update Agent on your Windows 10 computer manually, you can try resetting it instead and you can do it using the Reset Windows Update Agent tool which you can download from the official Microsoft website. This tool allows you to:

• • Scan all protected system file and replace the corrupted one’s (sfc /scannow)
  • Scan, detect, and repair corruptions in Windows system image
  • Clean up superseded components
  • Reset Windows Update components

• Change invalid values in Windows Registry
• Delete temporary files

Moreover, this tool also allows you to carry out these operations:

• Open Internet Explorer settings
• Search for Windows Updates
• Explorer for local or online solutions
• Restart your computer

Mozilla Firefox has introduced a new feature known as Restart with Windows which allows the browser to automatically start when your Windows 10 computer boots. This means that if you leave the Firefox browser opened while shutting down your computer, Firefox will re-open automatically along with the tabs that were opened right before you shut down your computer. Although some users may find this feature convenient, there are others who do not approve at all as it could be a nuisance. So if you’re one of the latter, then read on as this post will show you how you can disable the Restart with Windows feature in the Firefox browser on your Windows 10 computer. Refer to the instructions laid out below to get started.

• Step 1: Open Mozilla Firefox and if it’s opened already, just open a new tab and then type the following text in the address bar:

about:config

• Step 2: After typing the text given above, hit Enter and if a prompt with a warning message pops up, simply click on the “I accept the risk!” button to proceed.
• Step 3: Next, type “Restart” in the search filter which should display the following preference in the window:

“toolkit.winRegisterApplicationRestart”

• Step 4: After that, check for the preference value and then see if it’s set to true or not. If it is set to true, then it means that the Restart with Windows feature is enabled so obviously, to disable it, you need to set its value to false.
• Step 5: Now restart your computer without closing Firefox. After restarting your computer, you should no longer see Firefox starting automatically.

The Restart with Windows feature by default is disabled for most users. On the other hand, Mozilla will have this feature enabled as the default configuration in the coming weeks so it’s best that you now know what to do when that time comes since the newer versions of Mozilla Firefox are already being shipped with the Restart with Windows feature. However, if this post did not help you, then you might want to check if the feature has been added to the Startup folder, and from there, you can disable this startup program using the Task Manager > Startup tab.

The dialog boxes that you see on your Windows computer exist to send you a message or to notify you. However, you can also encounter issues with them. Recently, some users reported that they’re getting empty or blank dialog boxes. It’s definitely hard to choose between Yes or No or to click OK when you don’t know the context of the dialog box. If the same thing happened to you, worry not for there are some possible solutions that can help you fix the problem. This kind of problem usually happens when there are some issues with the graphics driver or when there is some corrupted software. Whichever the case is, here are some fixes you can check out to fix the empty or blank dialog boxes on your Windows 10 computer.

Option 1 – Run the System File Checker

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 with good system files that might be the cause why you’re getting the errors 0x8024a11a and 0x8024a112. To run the SFC command, follow the steps given below.

• 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 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: If updating the Graphics driver didn’t fix the problem, you can also try to roll back to its previous version and see if that helps.

Option 3 – Run the DISM tool

The next thing you can do is 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 blank dialog boxes. 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 – Try to repair or reinstall the software

If the issue with the empty dialog boxes only occurs in a specific program, you can either try to repair the program or reinstall it. You can find the Repair option in the Add/Remove program section when you select the concerned program. If repairing the program didn’t work, you might have to uninstall it and then reinstall it.

Option 5 – Try troubleshooting the problem in a Clean Boot State

You might also want to troubleshoot the problem in a Clean Boot State. Doing so will help you isolate the problem. Refer to the steps below to do so:

• 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.)

Method Two: Reset Windows Update Components

1. From your device’s desktop, hit Windows key + X to open the command prompt as admin.
2. Once the command prompt window appears, you can type or copy and paste the following commands (all at once):

net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:WindowsSoftwareDistribution SoftwareDistribution.old ren C:WindowsSystem32catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver pause

3. Exit the command prompt.
4. After you reset the Windows Update components, see if you receive Windows Updates which includes the firmware updates for your computer.

Method Three: Ensure Windows is Updated

1. If you have an antivirus, make sure to disable it during the upgrade process.
2. Run Windows Update to check if the system is updated.
3. Ensure that the latest firmware and drivers are installed. To be able to do this, go to the computer manufacturer’s website or you can also try contacting company support.

Running the Windows Setup does not always go smoothly as you could encounter some errors along the way. One of these errors is the “Something happened, Setup has failed to determine supported install choices” error. The only given option in such cases is to click the Close button and exit the setup. This kind of error in Windows setup can occur when you try to downgrade to the previous version of Windows using the built-in mechanism. This error could be caused by a corrupted image or it is also possible that the set of files are incomplete. Aside from that, it could also be due to compatibility issues or that the module used to downgrade the Windows operating system is not configured properly. To fix this error, you have to run the Windows Setup program in compatibility mode so that you can downgrade Windows. You could also use the image for the lower version of Windows that’s available on the official site of Microsoft. But before you do any of these, make sure that you’re logged in as an administrator. To fix the “Something happened, Setup has failed to determine supported install choices” error, follow the given options below sequentially.

Option 1 – Try to run the Installer of the downgraded version in Compatibility Mode

This is the first thing you can try to resolve the issue instead of going right ahead on making a bootable device. So if you are downgrading Windows, you can try to run the installer in the compatibility mode for that specific Windows version.

• Look for the setup file.
• Once you find it, right-click on it and select Properties from the context menu.
• After that, go to the Compatibility tab and mark the checkbox for “Run this program in compatibility mode for:” and from the drop-down list, select either Windows 7 or Windows 8.
• You also have to check the “Run as administrator” option.
• Now click the Apply button and then click OK to save the changes made and check if it has resolved the issue or not.

Option 2 – Try to troubleshoot compatibility

This option is almost the same as the first one except it is an alternative way of fixing the “Setup has failed to determine supported install choices” error in case the first one didn’t work. In this option, you will troubleshoot the compatibility issue.

• Look for the setup file.
• Then right-click on it and select the “Troubleshoot compatibility” from the context menu.
• After that, click on the “Try recommended setting” option. Once the process is done, the error message should be gone.

Option 3 – Run the DISM tool

You can run the DISM tool as well to help fix the error code 0x80244022 during Windows Update. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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 4 – Try using the image from the official site of Microsoft

If none of the options given above worked, you can try to use the image from Microsoft’s official site. This would help, especially if the error is caused by a corrupted image or image folder with incomplete files.
