If you are trying to update your Windows 10 computer but are not able to do so since your computer is running low on storage then this obviously indicates that there is not enough disk space available on your drive where Windows 10 has been installed. As you know, when Windows 10 downloads the update packages, it extracts them in a separate folder which means that there should be enough space on that particular folder for the update to begin with. Windows do not really check systems for any adequate space requirements before it even initializes the update or upgrades and you only get to know about it right when the update process starts. On Windows 10 thin clients or the ones with embedded systems that have limited storage space, when Windows Update runs, the update initialization may fail because as pointed out, Windows does not check systems for adequate space requirements so you may have to do the work for them by making sure that your disk has enough space available. Here are some suggestions you can follow to resolve Windows 10 update issues on computers with low storage space.

Option 1 – Delete the files from the Download folder

Since you are going to delete everything manually, you need to create a backup for all your important files which you may have placed in the Download folder. After you create backup copies of important files, delete the files from this folder or you could simply tap the Shift + Del keys to remove the files permanently after you selected them all.

Option 2 – Change the Windows Update Folder location

You might have to change the Windows Update folder location where Windows download all the files need to update the operating system if you cannot really create some space on your primary driver. So all you have to do is set the drive with enough space available for the update to be completed.

Option 3 – Uninstall apps and programs you no longer use

In some cases, apps and programs take up a lot of space on your drive. So if there are programs or apps that you no longer use, you can uninstall them to save storage space. To do so, follow these steps:

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the apps and programs that you no longer use and right-click on each one of them and click on Uninstall.

Option 4 – Move files to another drive

This is another thing you can try. You can move files, especially the ones with large sizes, to another drive to make up space on your drive. After that, install the updates once again.

Option 5 – Reduce on-drive files from Cloud services

If you are using tons of cloud backup services such as OneDrive and Dropbox, you might want to consider reducing the number of files you have on those cloud backup services. You can do what you’ve done on option number three and have those files moved to another drive to free up storage space.

Option 6 – Empty the contents in Recycle Bin

As you know, the files that are deleted from your computer goes to the Recycle Bin first. So if you have not emptied Recycle Bin for a long time now, the files you delete are still actually taking up space on your drive. Thus, you need to empty the contents in the Recycle Bin to save storage space.

Option 7 – Clean up temporary files

You can use the Windows 10 Storage Sense feature which can clean all the temporary files from your computer. To use Storage Sense, follow the steps below.

• 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

Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.

You can prevent starting of app installations files if they have not come from the MS store inside Windows 11. This can make your PC more secure because all apps in the store will have to be digitally signed and overall it can provide you with more control over what will be installed. Follow the guide below to find out how can you easily turn this feature ON.

1. Press ⊞ WINDOWS + I to open Windows settings
2. Select Apps and then choose Apps & Features
3. Click on Choose where to get apps to bring a drop-down menu
4. Select The Microsoft Store only (Recommended)
5. Close settings

Settings will apply changes immediately and you continue using Windows right away. With these settings turned ON if you want to install a downloaded application or run the installer you will not be able to, and message The app you’re trying to install isn’t a Microsoft-verified app will show on your screen. You can always reverse this setting by choosing Anywhere in settings instead of Microsoft store only.

Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

When you upgrade your Windows 7 or Windows 8.1 system to Windows 10, you’ll undergo a phase called Out of Box Experience, or simply OOBE. This phase is intended to allow users to customize their Windows 10 experience, which includes defining personal settings, creating user accounts, and more. Some users reported having issues when creating their user account during the Out of Box Experience (OOBE) on Windows 10 upgrade. Some also reported issues about non-responsive behavior (Welcome Back) page.

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.

There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:

• Your PC’s motherboard should support both Legacy and UEFI.
• Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.

Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

• 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.

• 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 UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

• When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
• Make sure to run Command Prompt as admin and then execute this command: exe /convert
• After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
• As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
• Now save the changes made and exit as your computer will restart.
