Files Older Than 3 Months Combined Total File Size

A requirement to identify the total file size of all files not used in the last 3 months.

This was the solution

#Run as administrator
#You need to have permission of the files or folders 

$date = (Get-Date).AddMonths(-3)

dir C:\temp -Recurse | ?{$_.lastwritetime -lt $date -and !$_.PsIsContainer} | Measure-Object -Property Length -Sum

# oneliner

dir C:\temp -Recurse -Force -ErrorAction SilentlyContinue | `

    ?{$_.lastwritetime -lt (Get-Date).AddMonths(-6)} | Measure-Object -Property Length -Sum -ErrorAction SilentlyContinue

 

# resulting data will be in bytes. To convert them to gigabytes, you may do this:

$files = dir C:\temp -Recurse -Force -ErrorAction SilentlyContinue | `

    ?{$_.lastwritetime -lt (Get-Date).AddMonths(-6)} | Measure-Object -Property Length -Sum -ErrorAction SilentlyContinue

($files.sum / 1gb).ToString(“F02”)

# F02 determines how much digits will appears after comma. In my case – 2 digits.

 

dir C:\temp -Recurse | ?{$_.psiscontainer} | %{

    Write-Host current folder is $_.fullname;

    dir $_.fullname | measure-object -property Length -sum -ErrorAction SilentlyContinue

} >c:\temp\file sizes

WSUS and Windows 10 Clients – UsoClient.exe

So, you deploy a GPO to Window 10 clients, but your in a hurry to get the clients to check in…

As a SysAdmin for many years I would log on to a client, open command prompt and type :

wuauclt /detectnow  (Windows 7 / Windows Server 2008/2012 clients)

 

In Windows 10 you will notice that it doesn’t do anything and doesn’t show you anything. (As shown above)

(confirmed on https://blogs.technet.microsoft.com/yongrhee/2017/11/09/wuauclt-detectnow-in-windows-10-and-windows-server-2016/)

An example of “Whats New” in Windows 10, and Windows Server 2016 To check or scan “Windows Update” from the command prompt :
CMD (Run As Administrator)
c:\windows\system32\

UsoClient.exe startscan

And there is more switches….

  1. StartScan – Used To Start Scan
  2. StartDownload – Used to Start Download of Patches
  3. StartInstall – Used to Install Downloaded Patches
  4. RefreshSettings  – Refresh Settings if any changes were made
  5. StartInteractiveScan  – May ask for user input and/or open dialogues to show progress or report errors
  6. RestartDevice – Restart device to finish installation of updates
  7. ScanInstallWait – Combined Scan Download Install
  8. ResumeUpdate – Resume Update Installation On Boot

Sysinternals – Permissions, LoggedOn, Endpoints

How to Get the permission on folders:
PowerShell:
Get-ChildItem | Get-ACL
Path | Owner | Access

or more in depth use:

GUI based : Run AccessEnum against the drive or folder – (SysInternals tool) and save to text file (Run as administrator or a specific user)

Who is logged on via the resource shares:
Launch cmd and run PSLoggedon (SysInternals tool)
Displays :
1) Users logged on locally
2) Users logged on via resource shares

List TCP and UDP Endpoints connected
Run TCPView application (SysInternals tool) and save to text file

Ever need to identify the before and after changes in Active Directory
Use : ADExplorer (SystInternals tool)

Check / Set / Sync Time Source for Windows Servers

To set the time ( Tested against Windows 2016)

Launch CMD as administrator
exampled c:\time 09:00:00 AM   – This will set the time to 9am

Note a time source if domain joined will up date the time clock again
Check the source
c:\w32tm /query /status Will show the time “Source”

To set an internet based NTP

c:\w32tm /config /syncfromflags:manual /manualpeerlist:”0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org
3.pool.ntp.org”

This will take effect after stopping and starting the W32Time service

Powershell….
stop-service w32time
start-service w32time

for settings to take effect

c:\w32tm /query /status Will show the new time “Source”

To check sync is working
c:\w32tm /resync (Check the time sync)
