If you are in the process of booting up your computer but suddenly encountered an error saying, “The Boot Configuration Data for your PC is missing or contains errors” with an error code of 0xc0000454, read on as this post will help you resolve the problem. The error code 0xc0000454 occurs when you boot your computer and when the Windows Boot Manager encounters an issue with the Boot Configuration Data or BCD. The error code 0xc0000454 (STATUS_INSUFFICIENT_NVRAM_RESOURCES) signifies that there are no sufficient NVRAM or Non-Volatile Random Access Memory resources to complete the API. NVRAM is a component of the system based on the software that stores the Boot Configuration Data in an operating system. Usually, a simple restart can resolve the problem. However, if you’ve already done that and it’s of no use, then there are other potential fixes you can check out to troubleshoot the problem. To resolve the error code 0xc0000454, here are some potential fixes that should help:

Option 1 – Try to repair corrupted BCD

As mentioned, the error could also be due to corruption in BCD, and to fix it, you can use Bootrec.exe – a built-in command-line tool used to troubleshot issues related to boot up and Windows Startup. Before you run this tool, make sure that you have inserted a bootable USB or DVD into your computer. Once you have that covered, follow these steps:

• You need to go to the Advanced Startup Options.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• Once Command Prompt has been pulled up, enter each one of the following commands and in the sequence that they are given to rebuild BCD files and repair MBR files:

The Microsoft Photos app is a useful tool that allows users to view, edit, as well as create videos on their Windows 10 computers. Although it works just fine most of the time, there are some instances when you might encounter some issues when using it. One of these issues is when you cannot save media from the Photos app after you’ve edited an image. This is most likely related to a permission issue. However, according to some users, they got the error where the edited media file can’t be saved. When you encounter this kind of error, you will see the following error in your Photos app:

“It looks like you don’t have permission to save changes to this file. Try saving a copy instead.”

There are several options you can explore to resolve this error. You can try updating the Microsoft Photos app or verify the ownership of the destination folder. You can also re-register and reinstall the app. For more detailed instructions, make use of the options provided below.

Option 1 – Try to update the Microsoft Photos app

The first thing you can do to fix the problem is to update the Microsoft Photos app.

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 2 – Try to verify the ownership of the destination folder

The next thing you can do to fix the error is to verify the ownership of the folder because chances are, the location where you’re trying to save the file might not have enough permissions to read and write the file to the disk. Thus, you need to take ownership of the folder by following these steps:

• Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
• After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Next, type and enter this command: TAKEOWN /F <path>
• Note that the <path> is the location of the folder or file in File Explorer.
• Now type and enter this second command: ICACLS <path> /grant administrators:F
• Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 3 – Try resetting the Photos app

If the first option of restarting the background process of the Photos app didn’t work for you, you can try to reset the Photos app so that it will use the default factory settings. Note that this option works when you are experiencing this issue after making a couple of changes in the Photos app.

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 4 – Try reinstalling the Photos app

If none of the first two options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

A lot of users complain about low storage space each time a Windows Feature update is released as well as to complain about not being able to download the updates, slow update experience, and many other complaints. The main issue is that many users do not have enough storage space available on their PCs. And now to make sure that none of the updates gets stuck because of low storage space, Microsoft presented the Reserved Storage feature which comes preinstalled with v1903 or those where v1903 was clean installed. This guide will be showing you how you can enable or disable the Reserved Storage in your Windows 10 computer. As you know, the Windows Update process should have enough space so that it can download, extract and apply the update on the computer. Usually, the size of the Reserved Storage is around 7GB which gives enough space for the update, temporary files, system caches, apps, and many more. And according to Microsoft, the size of the Reserved Storage space will vary from time to time and will depend on how you use your computer.

Explanation

The Reserved Storage space feature is enabled by default on devices that come preinstalled with the May 2019 update or after performing a clean installation of the Windows 10 OS. To check if your computer has this feature, you need to go to Settings > System > Storage and from there click on the “Show more categories” link and then click on the “System & reserved” option. However, if you can’t find the Reserved Storage from the list, then it’s probably because your computer has limited space on the hard disk or it is not a fresh or new install. On the other hand, if you have this feature but have no use for it and want to disable it instead, then read on as this post will also show you how it’s done.

Solution

Keep in mind that when you disable the Reserved Storage feature, chances are, you might be unable to enable it back so you need to make sure that it’s really what you want to do before you disable it permanently. So if you really want to disable Reserved Storage, you can do so using the Registry Editor. Before you proceed, you have to create a System Restore point first and then carry out the following steps.

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionReserveManager
• From there, double click on the DWORD named “ShippedWithReserves” and set its value to “1”.
• Once you’re done, restart your computer and see if the Reserved Storage feature is now gone.

On the other hand, if you want to reduce the Reserved Storage space, there are two ways you can do that. First, you can go to Settings > Apps > Apps & features > Manage optional features and from there, uninstall the optional features that you do not use. The second one is you have to go to Settings > Time & Language > Language and then uninstall the languages and their add-on which you don’t use. Note: The Reserved Storage feature is also used by system processes and apps to create temporary files and once the Reserved Storage space fills up, Windows 10 will delete them automatically. It is undeniable a useful feature so disabling it is not recommended but if you are running on low storage space and don’t have much choice, then you may disable it at your own risk.

The issue with the abrupt system reboots to force Windows 10 updates on a computer has been lessened with Active Hours. This feature keeps a record of the hours during which a system remains active and prevents the installation of updates during such hours. For example, when a system restart is needed to complete the installation of an update, Active Hours delays the update and allows you to finish what you’re doing on your computer. Thus, if you haven’t heard of this feature, then now is the time you do, read this post to configure and use Active Hours in your Windows 10 computer. There are three ways you can configure Active Hours. The first one is for general users, whereas the rest of the two methods are for users who knows their way about the Windows Registry and Group Policy. To get started, refer to every given option below.

Option 1 – Configure Active Hours via Windows 10 Settings

• Go to Settings > Update & Security. From there, click on the “Change active hours” option under the Windows Update section.
• Next, you can select a time (“Start time” and “End time”) during which the restart can occur.
• After that, click on the Save button and exit.

Note: Keep in mind that the values you’ve entered indicate the hours during which your system is in use, namely, ACTIVE. It is important for your active hour’s interval period and it can be anything between 1 and 18 hours since you can’t go beyond 18 hours. In addition, there is no option to configure different active hours on different days and you can’t specify different active hours for weekends and weekdays as well. On the other hand, Windows 10 also offer users an option to override Active Hours. All you have to do is go to Settings > Update & Security > Windows Update > Restart Options. From there, you can choose a custom restart time when your computer will restart to install the updates but this is only a one-time setting.

Option 2 – Configure Active Hours via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter or click OK to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsUpdateUXSettings
• In the given registry path, you can choose to change “ActiveHoursStart” and “ActiveHoursEnd”.

Note: There are no extra settings available in the Registry Editor but you can change the remote computer’s Active hours settings using the Registry Editor.

Option 3 – Configure Active Hours via Group Policy

Note that this option is available for the Windows 10 Pro and Educational or Enterprise versions. It is mostly used by computers in Business or through remote access. To get started, follow these steps:

• Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and tap Enter or click OK to open the Group Policy Editor.
• Next, navigate to this group policy setting: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Updates.
• From there, look for a policy labeled “Turn off auto-restart for updates during active hours” and double click on it. This will open a new window.
• Click on the Enabled radio button to enable Active Hours. You also have the option to choose active hours just like in the first given option above. It works just fine except when the following policies don’t override:
  • No Auto-restart with logged-on users for scheduled automatic updates installations.
  • Always automatically restart at the scheduled time.

• Since Group Policy allows you to reduce the range of active hours, you can configure it if you want it to be less than 18 hours. Just find the policy setting labeled “Specify Active hours range for auto -restarts. The minimum is 8 hours”.
• After you set the Active Hours, click the Apply and OK buttons to save the changes made.
