As you know, Windows PowerShell is a useful command-line utility in Windows 10 that can be used to manage the Local Users and Groups which affirms the multiuser operating system principle of Windows 10. Although there are other GUI-based utilities used to manage the Local Users and Groups, there are some system administrators that would still like to use the command-line utility to manage these Local Users and Groups. So in this post, you will be guided on how exactly you can manage the Local Users and Groups using PowerShell on your Windows 10 computer. To get started, refer to the options provided below to manage both the Local Users and Groups using Windows PowerShell.

Option 1 – Manage the Local Users via Windows PowerShell

• You need to first open Windows PowerShell as an admin. To do that, just tap the Win + X keys and select the Windows PowerShell (Admin) option.
• After opening PowerShell, you need to execute the “Get-LocalUser” cmdlet so that you can find all the details about all the local user accounts in your computer which would include the Account Name, Enabled status, as well as description.

Note: On the other hand, you can also get the customized data about several objects that are related to your account. For instance, if you want to check when was the last time the Local account’s password was set, then you need to execute the “Get-LocalUser -Name root | Select-Object PasswordLastSet” cmdlet. Thus, the structure for this cmdlet is “Get-LocalUser -Name root | Select-Object *”. Here are the objects you can use to get different sorts of data:

• AccountExpires
• Description
• Enabled : True
• FullName
• PasswordChangeableDate
• PasswordExpires
• UserMayChangePassword
• PasswordRequired
• PasswordLastSet
• LastLogon
• Name
• SID
• PrincipalSource
• ObjectClass

Option 2 – Manage the Local User Groups using Windows PowerShell

• Like what you did earlier, open Windows PowerShell as admin and then execute the “Get-LocalGroup” cmdlet so you can get all the information about all the groups of all the local user accounts.
• Now if you want to create a new Local User Group, just execute the “New-LocalGroup -Name <NAME OF THE GROUP> -Description '<ENTER THE DESCRIPTION OF THE GROUP HERE>'” cmdlet.
• And if you want to add Local User Accounts to a specific group, just execute the “Add-LocalGroupMember -Group '<NAME OF THE GROUP' -Member ('NAME 1','NAME 2','<ROLE>') -Verbose” cmdlet. You could also use the “Get-Localuser -Name john | Add-LocalGroupMember -Group '<NAME OF THE GROUP>'” cmdlet for the same purpose.
• If you want to display all the User Accounts of a specific group, just use the “Get-LocalGroupMember –Group ‘ ’” cmdlet.
• Now if you want to remove a local user account from a group, all you have to do is use the “Remove-LocalGroupMember -Group '<NAME OF THE GROUP>' –Member <NAME OF THE LOCAL USER ACCOUNT>” cmdlet.

If you receive an error message saying, “Windows Update cannot currently check for updates because updates on this computer are controlled”, while trying to change the Windows Update preferences or manually update, then read on as this post will guide you in fixing it. You can mostly encounter this error in managed systems where an Administrator controls the permission on the operating system. The reason why you are not able to modify the Windows Update preferences or manually update your system is that a group policy prevents you from doing so and that the only user who can do these things is none other than the administrator of the system. Troubleshooting this kind of problem is the same as when you troubleshoot an error message that says, “Some settings are managed by your organization”. In such cases, you need to check both the Windows Update Group Policy and Registry settings. If you’re just a standard user, you have to contact your system administrator regarding this issue and if you are the administrator, you can make adjustments to the system settings via the Registry Editor and the Group Policy Editor. Refer to the instructions given below for detailed instructions.

Option 1 – via the Registry Editor

If you are using the Home edition of Windows 10 and you want to change the policy for non-admin users on your local computer, then you can use the Registry Editor for that. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows

• From there, look for the key named “WindowsUpdate” in the Windows folder and if it does not exist, you can just right-click on the Windows folder and select New > Key.
• Now name the new key “WindowsUpdate” and create a new sub-key under the newly created key and input “AU” as its name.
• Keep AU selected and then right-click anywhere in the right pane and select New > DWORD (32-bit) Value.
• Then name the Value as “AUOptions” and right-click on AUOptions and select Modify.
• Next, change the value of the Value data to “5” and click OK to save the changes made to the settings. Note that the Value Data of 5 refers to the policy to allow the local admin to choose the setting.
• Now restart your computer once you’re done and check if non-admin users can now modify the Windows Update settings or update Windows.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” and hit Enter to open the Group Policy Editor.
• Next, navigate to this folder: Computer Configuration > Administrative Templates > Windows Components > Windows Update.
• Now look for the “Configure Automatic Updates” policy on the right pane and double click on it to open its Properties.
• After that, shift the Radio button to “Enabled” and from the drop-down menu for Configure automatic updating, select option 5: Allow local admin to choose the setting.
• Then click on Apply and OK to save the changes made to the settings.
• Restart your computer and check if the problem’s fixed or not.

Why combining hard drives with storage spaces? Ok, I will admit it, I am a modern digital hamster when it comes to digital goods. I like to collect stuff and more than anything else I like to have all of that at the tip of my fingers. And how digital goods grow in size themselves (movies on Blu-ray are like 50GB each) and the collection grows in size single hard drive is starting to be completely obsolete when it comes to storage. Sometimes we will need large storage for these kinds of personal collections, sometimes we will need it for work reasons. Whatever your reason might be Windows 10 is offering us a solution via Storage spaces. Storage spaces is an integral part of Windows and it is meant as a tool to provide you with a RAID environment without a RAID controller. Of course, combining multiple hard drives via storage paces instead of RAID will not be so fast or stable but for home use of storing a large quantity of data is perfectly enough. With Storage Spaces you will also have an option to reduce some space for increased security of data loss if by any chance one of your HDD fails.

How to Create a Storage Space

To create storage space in Windows, press ⊞ WINDOWS + R to open the run dialog. In the run box type in Control Panel and press ENTER In Control Panel find Storage Spaces and left-click on it. Once storage spaces open, left-click on Create a new pool and storage space Once you click on create new, you will be greeted with a list of hard drives you can use for this operation. Please note that all hard drives you choose will be completely erased and formatted and then assign a single drive letter. Click on Create pool. You will find yourself in new storage options where you can assign a drive letter, give storage space a name, etc.

Storage spaces types

One thing I would like to focus on here is resiliency type, when you expand the resiliency type drop-down menu you will see 4 options inside. Simple, Two-way mirror, Three-way mirrors, and Parity. Simple: If you choose Simple as an option, you will have maximum hard drive space but no resiliency at all, meaning that if by any chance any of your hard drives malfunction, you are losing your data from that drive completely. Two-way mirror: This option will save your data if one of your drives fails but you need at least 2 drives and storage space will be limited since some of it will be a safe backup option for the case of a drive failure. However if one of your drives fails, you can replace it in a second and keep on working as nothing happened. Three-way mirror: This option similar to the previous one will offer you safe data-keeping from a hard drive failure. this option will save your data even if 2 hard drives malfunction but it will require having 5 of them connected in order to be able to choose this option. Parity: Maybe the most popular option among people who want to have 2 or 3 drives merged but do not want to lose too much space of the two-way mirror option. It offers some protection and it does not take so much space as two-way does, let us say it is a kind of win-win situation.

Conclusion

I personally go for simple and have an important backup on optical drives but only for reason I could use more space, know that this way is requiring from me to always have a backup in optical media and that I will need to restore all of it back if even one HDD fails which could take time. But if this way is ok with you, go for it, you will have more space to use.

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• 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.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Option 2 – Perform System Restore

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• 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.

 Restart your computer and see if the System32 folder still pops up at startup or not.

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.
