Show/Hide Security Tab in Windows 10

Using Windows Registry

Open the registry of your system by typing “regedit.exe" in Run window. And go to following directory
HKEY_CURRENT_USER\Software\Microsoft\Windows\Currentversion\Policies\Explorer

When you open it, in right window you’ll see the “NoSecurityTab" change its value to 1 by modifying it. And refresh your window. And here you go. Security tabs from each folder will hide from every one.

Whenever you want to show it again, again go to same registry path and set its value to 0 again, the security tab will be visible again.

Using Group Policy Editor

You can also show/hide “Security" tab through Group Policy editor. Open the “Local Group Policy editor" by writing it in Start Menu. Then open the first result it gives you on typing.
Now open the User Configuration\Administrative Tools\Windows Components\File Explorer and double click on it, now open Remove Security Tab from right hand side window.

When you open “Remove Security Tab", there is 3 options: not configured, enable and disable.
If you want to remove Security Tab, select the “enable" and if don’t then press on “disable".

After selecting any option press “OK" and your settings will be changed. This is another easy and simple way to hide/show Security tab.

Using command line

Giving specific commands on Command Line Window can also enable or disable the “Security" tab.
Following are commands for enabling and disabling the “Security" tab.

Enable Security Tab

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer /v Nosecuritytab /t REG_DWORD /d 0 /f

Disable Security Tab

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer /v Nosecuritytab /t REG_DWORD /d 1 /f

After entering your required command, press enter and close the CMD and you are done with enabling or disabling the Security Tab.
Above three are easy and simple ways for your problem of enabling or disabling the Security Tab. You can go for anyone of them. All are simple and reliable ways.

Windows 10 Start menu not working after joined to Domain

here may be many scenarios this could happen.  in this scenario you may be having a Windows 2008 R2 domain controller with this kind of group policy setting for registry (this is not a default group policy setting)


And These are the Default Permissions for this Registry Entry


The problem is For windows 10 “CLASSES_ROOT” need more permission to Access Windows Start menu settings
With Windows 2008 R2 Domain controllers this permission group is not available.If you need to add customized group policy settings for “CLASSES_ROOT” you need to have Windows 2012 R2 Domain controller or server 2016 domain Controller in your environment.

This is a screen shot from default settings for “CLASSES_ROOT” in Server 2016 Domain controller



What happen is When you modify that Registry entry with a Group policy in Windows 2008 R2 domain controller.Windows 10 Client PC will loss “ALL APPLICATION PACKAGES” FROM reading CLASSES_ROOT Registry permissions.
If your having only Windows 2008 R2 domain controller.
Delete This Group policy setting
Computer configuration > policies > Windows settings > Security Settings > registry > “CLASSES_ROOT”
run “gpupdate /force” on windows 10 Client PC
Login to Windows 10 PC As Domain Administrator
Go to Registry (Press Windows key + R and type regedit and press enter)
right click HKEY_CLASSES_ROOT And click permission and add “ALL APPLICATION PACKAGES” Group from LOCAL computer and give read only permission

Then click “Advanced” Button and tick “Replace all child object permission entire with inheritable permission entries from the object” and click apply it might take some time to apply settings.click OK and close registry editor and reboot.
If you have  introduced a 2012 R2 or a Server 2016 Domain controller to the existing domain with 2008 R2 you can just edit the Group policy setting for CLASSES_ROOT From 2012 R2 Domain controller Group policy editor and edit CLASSES_ROOT and click on “Add” Button > click “Location” Button > Select “LOCAL COMPUTER NAME” and Click OK.
Click “Advanced” And click “Find” then Select “ALL APPLICATION PACKAGES” Group click OK Twice and give “Read only” permissions for “ALL APPLICATION PACKAGES” Group.Click OK to save. run a “gpupdate /force” on the client computer and reboot.
that’s it, hope this will help to fix start menu not working problem in windows 10 ,even if your not in a domain environment you can just check this registry entry for correct permissions.

How do I add an SPF record? (Note that the SPF format has been deprecated due to the DNS RFC )

 How do I add an SPF record?

Sender Policy Frame (SPF) record specifies the list of approved hostnames (or IPs) from where email can originate for a particular domain.

To set up an SPF record:

1. Log into your Cloudflare Account. 
2. From the drop-down on the top left, select your domain.
3. Click the DNS app at the top of the page.
4. Under DNS Records, complete the fields for your TXT record, including your SPF values record (see image below). 
5. Choose TXT. Enter the Name of the record and its corresponding value.
   
6. (optional) Add your SPF format record string under the value section and click Add Record. Note that the SPF format has been deprecated due to the DNS RFC and thus, you should always have at least the TXT record definition present, even if you use the SPF type.

More information on SPF record syntax and formatting is found below.
The mechanisms can be prefixed with one of four qualifiers:

Prefix	Qualifier
+	Pass
-	Fail
~	Soft Fail
?	Neutral

Evaluation of an SPF record can return any of these results:

Pass	Explanation	Intended action
Pass	The SPF record designates the host to be allowed to send.	Accept
Fail	The SPF record has designated the host as NOT being allowed to send.	Reject
SoftFail	The SPF record has designated the host as NOT being allowed to send but is in transition.	Accept but mark
Neutral	The SPF record specifies explicitly that nothing can be said about the validity.	Accept
None	The domain does not have an SPF record or the SPF record does not evaluate to a result.	Accept
PermError	A permanent error has occurred (e.g. badly formatted SPF record).	Unspecified
TempError	A transient error has occurred.	Accept or reject

For more information about SPF Record Syntax, see, Open SPF project - syntax.
If you're unsure, double check what the value should be with your mail service provider.

Difference between vSphere, ESXi and vCenter

VMware Inc. is a software company that develops many suites of software products specially for providing various virtualization solutions. There are many cloud products, datacenter products, desktop products and so on. VMware has moved from being just a Virtualization company, though it started as one.
VMware Vsphere or simply known as vSphere is a software suite that comes under data center product. vSphere is like Microsoft Office suite which has many softwares like MS Office, MS Excel, MS Access and so on. Like Microsoft Office, vSphere is also a software suite that has many software components like vCenter, ESXi, vSphere client and so on. So, the combination of all these software components is vSphere. vSphere is not a particular software that you can install and use, “it is just a package name which has other sub components”.
ESXi, vSphere client and vCenter are components of vSphere. ESXi server is the most important part of vSphere. ESXi is the virtualization server. It is type 1 hypervisor. All the virtual machines or Guest OS are installed on the ESXi server. To install, manage and access those virtual servers which sit on top of ESXi server, you will need other part of vSphere suit called vSphere client or vCenter. Now, vSphere client allows administrators to connect to ESXi servers and access or manage virtual machines. vSphere client is installed on the client machine (e.g. Administrator’s laptop). It can also be installed on the same physical server where ESXi is installed. The vSphere client is used from client machine to connect to ESXi server and do management tasks. So now what is vCenter? Why we need it? Try cloning existing virtual machine using just a vSphere client without vCenter server and you will see it is impossible.
vCenter server is similar to vSphere client but it’s a software with more power. vCenter server is installed on Windows Server or Linux Server or desktop/laptop. VMware vCenter server is a centralized management application that lets you manage virtual machines and ESXi hosts centrally. vSphere client is used to access vCenter Server and ultimately manage ESXi servers. vCenter server is compulsory for enterprises to have enterprise features like vMotion, VMware High Availability, VMware Update Manager and VMware Distributed Resource Scheduler (DRS). For example, you can easily clone existing virtual machine in vCenter server. So vCenter is another important part of vSphere package. You have to buy vCenter license separately.
vSphere is a product suite, ESXi is a hypervisor installed on a physical machine.
vSphere Client is installed on laptop or desktop PC and is used to access ESXi Server to install and manage virtual machines on ESXi server.
vCenter server is installed as virtual machine on top of ESXi server. vCenter server can also be installed on different standalone physical server, but why not virtualize it too right? vCenter server is a vSphere component which is mostly used in large environment where there are many ESXi servers and dozens of virtual machines. The vCenter server is also accessed by vSphere client for management purpose. So, vSphere client is used to access ESXi server directly in small environment. In larger environment, vSphere client is used again to access vCenter server which ultimately manages ESXi server.
Virtualizing the vCenter server.
If the ESXi host that houses the virtual vCenter server becomes inaccessible, then the services are interrupted and you cannot connect to the server. This will cause all sorts of headaches. The only solution is to log into each ESX host and see where the vcenter server is present. You can build a physical vCenter server and domain controller to alleviate this issue. Although you can virtualize any application, I do not think all applications should be. Just some admin advice and experience when planning your virtual environment. However, this can be addresses by getting one or two extra hosts so vcenter can restart itself on another host.
