Inserting landscape in a specific page in a word document can be done by inserting section breaks. Let’s just make a basic example.
Let’s say you have 3 page document and you want that first page in Portrait mode, second page in landscape and third page in portrait layout also.
First, click on “home” tab, click the “show/hide paragraph marks” option or see the icon below. Enabling this option the section breaks, spaces and tabs will be visible. But what we are interested is to see the “section breaks”.

Svchost process in task manager

Svchost.exe contains generic host processes.

If the svchost.exe is accidentally close or intentionally close, then the system might crash or shutdown.

There are times that svchost.exe does consume quite a lot of resources and eats up the memory on the system. Thus, it's quite tempting to close or kill the process.

To kill or close a process forcefully via command line can be done using taskkill command plus the process id.

Ex: Taskkill /pid 1234

How to know exactly which service or process the svchost is running?

To check the pid and the process that svchost is running, type:

tasklist /svc

Tasklist /svc command will display the image name, pid and the services.

Output example for tasklist /svc command:

svchost.exe                   1172 EventSystem, fdPHost, FontCache, netprofm,
                                   nsi, W32Time, WdiServiceHost
svchost.exe                   1200 Appinfo, BITS, Browser, CertPropSvc,
                                   EapHost, IKEEXT, iphlpsvc, LanmanSe…

This can be done easily using PowerShell script.

Script below requires PS 3.0, but it can easily be tweak for other version.

Here's the script:

#++++++++++++++++++++++++++++++
$source_folder="D:\xfolder\United Folders"
dir -Directory "D:\Unity\Project_016\" | ForEach-Object {
write-host $_.fullname
Copy-Item -Path $source_folder -Destination $_.FullName
}
#++++++++++++++++++++++++++++++

Example:
D:\Unity\Project_016\01
D:\Unity\Project_016\02
D:\Unity\Project_016\03

After executing the script, the folders will look like this:
D:\Unity\Project_016\01\United Folders
D:\Unity\Project_016\02\United Folders
D:\Unity\Project_016\03\United Folders

Active Directory GPO apply to forest

How to apply GPO to whole forest?

1. Open GPMC (Group Policy Management Console) and create a GPO for a single domain.

2. Link the GPO to other domains in the forest.
   Right click each domain and select "Link an Existing GPO Here" then select the GPO that will be applied to all domains in the forest.

3. If everything works fine, then you're a lucky man.


Before rolling out a GPO create a test Organizational Unit and create Active Directory user accounts for test purposes.

Then apply the GPO to the OU.

If it works properly then there's a good chance that it will work smoothly to all users but it's not a guarantee that it will work correctly to all users.

If the GPO is critically needed to be applied to all users and testing works okay, roll out the GPO and troubleshoot issues that may occur.

If no problem arises, then drink a cup of coffee and consider yourself "lucky".

If the GPO is not yet tested and you are not sure whether it will havoc the Active Directory …

PowerShell Copy Specific File Extension

PowerShell Code snippet to copy files with a particular extension.
$extension = ('.pdf', '.docx', '.txt')
Gci d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
} | % {Copy-Item $_.FullName d:\mix_backup}
To read files with specified filename extension.
$extension = ('.pdf', '.docx', '.txt')
Dir d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
}

or
$extension = ('.pdf', '.docx', '.txt')
Gci d:\WorkFolder $_ | Where-Object {
$extension -contains $_.Extension
} | % {write-host $_.FullName }

Copying files with the long path will result to an error.

Below is the modified code that uses robocopy to copy files with long paths.

Do not interchange source and destination when using robocopy, the files will be overwritten.
