PowerShell get windows update


Updates are good if they will not mess up with the Operating System.

But since nothing is perfect in this world, updates could crash the system or worse create problems that will puzzle the IT guy.

Different hardwares, different third party softwares installed or custom applications, install on  a server or computer. That some updates will work perfectly on other systems but may create issues on other systems.

Troubleshooting the whole system trying to figure out what could be the culprit, but on the end messing up the whole system.

Bottom line, some updates may introduce some issues or mess up the system.

If you need PowerShell to list  all the updates, here is a simple code snippet to list all the KB Hotfix ID updates installed on the system.

======================================

$xUpdate =Get-WmiObject -Class WIN32_QuickFixEngineering | select HotFixID
foreach ($LineUpdatex in $xxUpdate) {
write-host $LineUpdatex `n
}


======================================

Sample output will be like this:

@{HotFixID=KB3008627}

@{HotFixID=KB3010788}

@{HotFixID=KB3011780}

@{HotFixID=KB958488}

@{HotFixID=KB976902}

@{HotFixID=KB982018}


Get-Hotfix cmdlet is quite handy also.

Cheers!! Hope it helps!!!

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…
