Quick Fix For 0x80004005 Outlook Error

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:
  • Network Virtualization Service
  • Virtual Disk
  • Hyper – V Virtual Machine
  • Hyper – V Host Computer Service
  • Container Manager Services
• After you find the aforementioned services, make sure to check if they are enabled or not and then restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.

If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message. In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below. Step 1: Tap the Win + R keys to open the Run utility. Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt. Step 3: After opening Command Prompt, execute the following command:

rd \.file-folder-path /S /Q

Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:

rd \.C:Users<username>DesktopCON /S /Q

However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.

FSUTIL reparsepoint delete C:Users<username>DesktopFileName DEL C:Users<username>DesktopFileName

As you know, networks that are domain-based are common in organizations and companies. These domain-based networks require multiple computers to be controlled through a single node known as a server. And the one that sets certain policies and restrictions on every system that is joined to the domain is the server administrator. So if you want to add your computer to a domain, you need to have the following information available:

• The domain name
• A user account name that’s registered in the active directory associated with the server
• Windows Enterprise, Pro, or education version

In this post, you will be guided on how you can join or remove a domain. To get started, follow the given instructions below.

Option 1 – Joining a domain

• First, you need to connect your computer to the network associated with the server since your computer and the server have to be on the same network.
• Next, click the Start button and then click on the gear-like icon for Settings to open it.
• After that, navigate to this path: Accounts > Access work or school.
• Then click on Connect. This will open a new dialog box and from there, select the “Join this device to a local Active Directory domain” option.
• Afterward, you will be asked to enter the username and password of your domain account.
• Now select your Account type and when you proceed, you have to restart your computer. Your domain account should now be created.

Option 2 – Removing a domain

• You need to open the Windows 10 Settings app.
• And from there, go to this path: Accounts > Access work and school.
• Next, select the account you want to remove from the domain and then click on Disconnect.
• A prompt will then appear that says, “Are you sure you want to remove this account? This will remove your access to resources like email, apps, network, and all content associated with it. Your organization might also remove some data stored on this device”. Just click on Yes.
• This will give you a Disconnect from the organization prompt.
• Now click on Disconnect and select Restart now to restart your computer. This will complete the removal process of the domain.

Hello and welcome everyone. In today's article, you will learn how to lock folder and content in it. Please be aware of few things:

1. The method is shown here works, but you need to be careful and follow step by step or you will damage your files permanently,
2. If you forget your password, you can not access your files anymore
3. Your files altho protected can still show up in recent files of some applications

All of that being said, let us start with locking the local folder on the computer with the password. Go to the folder where you have files that you would like to hide and lock with a password. Enter the folder and create the new text file inside it. Skip the name for now and go inside it. Copy and paste the following code inside the file:

---

cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Are you sure u want to Lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to Unlock folder set/p "pass=>" if NOT %pass%==Your-Password-Here goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md Locker echo Locker created successfully goto End :End

---

Now locate this line of code in the document: if NOT %pass%==Your-Password-Here goto FAIL and replace Your-Password-Here with your password. !!! Write down somewhere your password, if you lose it you will lock the folder even for you !!! Save the file as FolderLocker.bat and double-click on it to execute it. If everything was done correctly, a new folder with the name: Locker Move files that you want to hide and protect inside that folder. Double click again on FolderLocker.bat The command prompt will appear with the question do you want to lock the folder, press Y, and press ENTER. The command prompt will close and the Locker folder will disappear. In order to unhide and access the folder, you will need to double click on FolderLocker.bat again but this time command prompt with ENTER your password will appear. Type in your chosen password and the folder is back. If you wish to hide and lock it again just double click on FolderLocker.bat again, confirm with Y and it is hidden again.

Today most users have an SSD drive, times have changed and SSD has become your typical computer equipment. A lot of time has passed from the first SSD hard drives up to today and technology has evolved and improved but still, there are some cool tricks and tips to speed up and extend the lifespan of your SSD hard drive. That being said let us dive right into what I would like to call the essentials of having an SSD hard drive.

1. Keep your SSD firmware up to date.

   This one really is a no-brainer, keeping your firmware updated at all times will ensure longer life and SSD stability. The trick here is that each SSD manufacturer has its own ways of updating firmware so this is not something universal, you will have to go to the official website of your SSD manufacturer and get firmware updates and instructions from them directly.

2. Enable ACHI.

   Advanced controller host interface or short ACHI is a feature that will ensure that your Windows will support all of the features that come with running SSD on your computer. It controls the TRIM feature which is crucial in helping Windows itself in its garbage collection on your hard drive. In order to enable ACHI, you will have to do it from your BIOS and it would be very good if the feature is enabled before Windows itself is installed so it can take full advantage of it.

3. Enable TRIM.

   TRIM feature is vital in extending your SSD lifespan and it should be enabled by default in Windows but you can never be too cautious and double-check and enable if needed. To make sure it is enabled, open your command prompt and type in: fsutil behavior set disabledeletenotify 0

4. Make sure your system restore is enabled.

   In the first SSD days, system restore was really a feature that you wanted to be disabled in order to prevent and extend the life span of your SSD drive, but we came a long way from there and today there is no reason to keep this feature turned off since it can be helping many ways with both your system and SSD.

5. Disable Indexing in Windows.

   A large portion of the speed of your SSD drive is used for indexing files in Windows. Of course, the indexing feature is great if you store everything on your SSD drive but if by any chance you have another drive for your backup, pictures, music, etc. it would be highly beneficial for you to turn it off on your SSD. To turn indexing off click on your start menu, click on the computer. Right-click on your SSD and then click on properties. De-select box that says: Allow files to have contents indexed in addition to file properties and click OK. Once you do this the operating system will apply this to all the files and folders on the drive. If you see a dialog telling you that it couldn’t remove a file from the index, click Ignore All.

6. Keep Windows defrag ON.

   This also was the option in early SSD days which was better to be OFF, but as said before since technology has been making progress and Windows has been improved and made aware of SSD drives, defrag has evolved as well, and now it is more of optimization tool then defragmenter which was once.

7. Disable Prefetch and Superfetch.

   Windows is placing information in both physical and virtual memory for applications that you are not currently using but they are used often in order to speed their response time. If you are running low on space or having struggles with virtual memory it would be best to turn them both off. Go to registry manager and find: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters, there you have 2 values: EnablePrefetcher and EnableSuperfetch, set both values to 0.

8. Disable Search and Superfetch services.

   Disabling Superfetch in the registry is not all work, Press WINDOWS + R to bring run dialog, type in it services.msc, Find both Search and Superfetch and disable them.

9. Configure Write Caching.

   Write caching can be enabled and disabled in the device manager by expanding disk drives, right-clicking on SSD, then click properties, select the policies tab. In the tab, there is the option to Enable write caching on the device. Now trick in this is that you will need to try and benchmark your SSD with both options turned ON and OFF since different manufacturers have different performances with this option being ON or OFF.

10. Disable CleanPageFileAtShutdown and LargeSystemCache.

    Page file and a large cache of page files are not something that we longer need, since SSD writes with great speed in its flash memory both of these options can be disabled and you will both speed up shut down the process of your system and save some SSD life since page files will not be written. Find both options in the registry under the key: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management set both to 0

11. Set high performance in Power options.

    This option in power management will prevent your SSD from constantly shutting down and bringing it up increasing speed without sacrificing its life span.

These are tips and tricks for having great and longer life as well as speed for your SSD drive. We hope that you have found them useful and that you will come again to check new articles published daily for easier IT life.

Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.

Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.

So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.

SONY PLAYSTATION VR

If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.

While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.

VALVE Index

Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.

The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.

However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.

META QUEST 2

Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.

Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.

Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.

Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.

Error Code 0x80070005 – What is it?

Error code 0x80070005 is also known as the “Access Denied” error code because it prevents Windows users from accessing updates on their machines. This error code exists due to a lack of permissions on one’s system files or registry, permissions which are necessary for the updates via Windows Update to complete successfully.
