Error: No Internet access from IPv6 .

If you see the IPv6 No network access from Ethernet Status dialog then you can try this tutorial.
Use Start menu then type cmd to start the Command Prompt shell and use right click choose Run as administrator.
Use this commands into shell:

You can also use the ipconfig command-line tool

Windows 10 – SubInACL tool.

This tool can be found at microsoft website and is a powerful tool.
After install the tool complete html documentation with useful examples.
You must run this command with administrator privileges.
Also they tell us about this tool:
SubInACL is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain.

For example, if a user has moved from one domain (DomainA) to another (DomainB), the administrator can replace DomainA\User with DomainB\User in the security information for the user’s files. This gives the user access to the same files from the new domain.

SubInACL enables administrators to do the following:

Display security information associated with files, registry keys, or services. This information includes owner, group, permission access control list (ACL), discretionary ACL (DACL), and system ACL (SACL).
Change the owner of an object.
Replace the security information for one identifier (account, group, well-known security identifier (SID)) with that of another identifier.
Migrate security information about objects. This is useful if you have reorganized a network’s domains and need to migrate the security information for files from one domain to another.

For example:

come with infos like :

Go – simple or not.

In this tutorial I will show you how important it is to read the documentation in programming.
I’ll start with a simple command to detect the go language version

Most will say there are improvements and it is normal to know them.
Some of them will think that implementation is not obvious at a more general level and does not affect basic issues.
Let’s continue with the following example:

Obviously the word “Probably” will ask us a question mark.
Here’s what the documentation tells us:

func (*Int) ProbablyPrime
func (x *Int) ProbablyPrime(n int) bool
ProbablyPrime reports whether x is probably prime, applying the Miller-Rabin test with n pseudorandomly chosen bases as well as a Baillie-PSW test.

If x is prime, ProbablyPrime returns true. If x is chosen randomly and not prime, ProbablyPrime probably returns false. The probability of returning true for a randomly chosen non-prime is at most ¼ⁿ.

ProbablyPrime is 100% accurate for inputs less than 2⁶⁴. See Menezes et al., Handbook of Applied Cryptography, 1997, pp. 145-149, and FIPS 186-4 Appendix F for further discussion of the error probabilities.

ProbablyPrime is not suitable for judging primes that an adversary may have crafted to fool the test.

As of Go 1.8, ProbablyPrime(0) is allowed and applies only a Baillie-PSW test. Before Go 1.8, ProbablyPrime applied only the Miller-Rabin tests, and ProbablyPrime(0) panicked.

About prime numbers:

When a number has more than two factors it is called a composite number. Here are the first few prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199

Although both Baillie-PSW test and Miller-Rabin tests, solve the same problem.
Knowing which version we have, we can see what is important for programming.
Also, the information like: ProbablyPrime is 100% accurate for inputs less than 2⁶⁴ are very important from a mathematical point of view.

Windows 10 – WinSxS folder and DISM tool .

NOTE: Deleting files from the WinSxS folder or deleting the entire WinSxS folder may severely damage your system so that your PC might not boot and make it impossible to update.
The DISM command tool let you to deal with WinSxS folder.
You can use DISM with Windows cabinet (.cab) or Windows Update Stand-alone Installer (.msu) files to install or remove updates, service packs, language packs, and to enable or disable Windows features.
Let’s see some examples for this tool:
First , use analysis you can determine the overhead of the WinSxS folder:

In this example, the WinSxS folder appears to be 5.18 GB, but the actual overhead (the sum of the size of backups and disabled features and the size of cache and temporary data) is 551.75 MB.
This tool aslo provides more options to further reduce the size of the WinSxS folder:

The last option ( is not show in this tutorial ) is to analyze the size of the Component Store in an offline Windows image.
You need to copy a .wim file, a .vhd, or a .vhdx that contains a Windows image and then you can start cleanup of the image.

Using wmic command under Windows 10 – part 003.

According to microsoft official website , see the link you can change the execution priority of the processes.
You can see this two examples with wmic commands:
