Rumors of Cmd’s death have been greatly exaggerated – but it still pays to switch to PowerShell

Posted by jpluimers on 2018/03/21

About a year ago, [WayBackRumors of Cmd’s death have been greatly exaggerated – Windows Command Line Tools For Developers got published as a response to confusing posts like these:

But I still think it’s a wise idea to switch away from the Cmd and to PowerShell as with PowerShell you get way more consistent language features, far better documentation, truckloads of new features (of which I like the object pipeline and .NET interoperability most) and far fewer quirks.

It’s time as well, as by now, Windows 7 has been EOL for a while, and Windows 8.x is in extended support: [WayBackWindows lifecycle fact sheet – Windows Help:

Client operating systems  Latest update or service pack  End of mainstream support  End of extended support
  Windows XP  Service Pack 3  April 14, 2009  April 8, 2014
  Windows Vista  Service Pack 2  April 10, 2012  April 11, 2017
  Windows 7*  Service Pack 1  January 13, 2015  January 14, 2020
  Windows 8  Windows 8.1  January 9, 2018  January 10, 2023
Windows 10, released in July 2015**  N/A  October 13, 2020  October 14, 2025

Which means the PowerShell version baseline on supported Windows versions is at least 4.0: [Archive.iswindows 10 powershell version – Google Search and [WayBackPowerShell versions and their Windows version – 4sysops

PowerShell and Windows versions ^
PowerShell Version Release Date Default Windows Versions
PowerShell 2.0 October 2009 Windows 7 Windows Server 2008 R2 (**)
PowerShell 3.0 September 2012 Windows 8 Windows Server 2012
PowerShell 4.0 October 2013 Windows 8.1 Windows Server 2012 R2
PowerShell 5.0 April 2014 (***) Windows 10

So try PowerShell now. You won’t regret it.

Finding out when your domain password will expire :: Active Directory :: Admin Tips :: Windows 7 :: Windows Server 2012/2008/2003/2000/XP/NT Administrator Knowledge Base :: KBase Tips :: WindowsNetworking.com

Here’s how you can find out when your domain password will expire.

net user %USERNAME% /domain

It figures this out for the current logon domain (so it doesn’t work cross-domain) but it is a great help, especially when filtering out just the password information:

net user %USERNAME% /domain | findstr "Password"

This can be done in a more complex way with dsquery or adinfo that are tools to query

Consolidating NTFS free space

Posted by jpluimers on 2017/12/29

For shrinking VM disk images, it’s important to consolidate NTFS free space towards the end of the this.

I’ve tried many tools, starting with defrag C: /X (which tries, but doesn’t give good results) and found out these steps give the best results:

  1. Perform an Ultradefrag full optimisation,
  2. Perform a MyDefrag Consolidate free space script on the drive.

If shrinking still fails then:

  1. Try the Ultradefrag at boot time
  2. Verify what kind of file(s) prevent shrinking: they show up in red after the MyDefrag session:
    1. Zoom in them (they can initially as small as 1 red pixel) by clicking on or near them, repeating the zoom long enough so you can hover over with the mouse and the lower part of the screen shows a filename like  where you cannot find much information about “$badclus:$bad:$data” but appear to be clusters marked as bad on NTFS level using something like chkdsk /B.
    2. If it was a bad sector like above, then try to resolve it with [WayBackntfsfix which ships with GParted live boot:
      1. boot a [WayBackGParted — Live CD/USB/PXE/HD drive,
      2. run GParted to see the drive path (for instance /dev/sda1)
      3. start a terminal
      4. run this command:
        ntfsfix -b /dev/sda1
        which will give output like this:

        Mounting volume... OK
        Processing of $MFT and $MFTMirr completed successfully.
        Checking the alternate boot sector... OK
        NTFS volume version is 3.1.
        Going to un-mark the bad clusters ($BadClus)... OK
        NTFS partition /dev/sda1 was processed successfully.
      5. boot back into Windows
      6. on an administrative command prompt run this for the affected drive letter:
        chkdsk D: /B
        (reboot if needed)
  3. Shrink the drive using diskmgmt.msc

If you still cannot shrink, then try [WayBackhttp://ftp.raxco.com/pub/download/pd14.0/pd14.0_pro.exe PerfectDisk by Raxco free trial.

Note:

MyDefrag (formerly named JkDefrag) is not maintained any more but the 4.3.1 version in the WayBack machine still works very well as the underlying defragmentation APIs in Windows haven’t changed.

Task Scheduler – command-line End a Running Task

Posted by jpluimers on 2017/12/11

schtasks /End [/S <system> [/U <username> [/P [<password>]]]] /TN taskname

[WayBackEnd a Running Task

Every now and then you have those Scheduled Tasks consisting of batch files that – despite trying – still ask for user input.

If – even after a reasonable time out – the Task Scheduler still hasn’t killed them, you can kill them by hand with the above schtasks in a snap.

VHD Attach 4.11 – Medo’s Home Page

Posted by jpluimers on 2017/06/05

Brilliant:

This is small tool that adds Attach and Detach option to contextual (aka right-click) menu of Virtual disk (vhd) files. That enables those operations to be done without trip to Disk Management console. Detach option is available on hard drive contextual menu also (if selected in options).

17 years ago, C:\nul\nul crashed/BSOD Windows; now $MFT does for Windows < 10

History repeating itself: [Archive.is31607 – C:\nul\nul crashes/BSOD then, now it’s this:

Via:

All versions prior to Windows 10 and Windows Server 2016 seem vulnerable.

So add $MFT to this list:

The following device names have been known to render a system unstable: CON,
NUL, AUX, PRN, CLOCK$, COMx, LPT1, and CONFIG$.

Oh BTW: history repeated itself this year too. With NUL

In short, Steven Sheldon created a rust package named nul which broke the complete package manager on Windows:

BTW: one of my gripes on learning new languages is that they come with a whole new idiom of their ecosystem: rust, cargo, crates, all sound like being a truck mechanic to me.

Two Quick Methods for Finding Shared Folders in Windows

Posted by jpluimers on 2017/05/01

In addition to the two methods mentioned at Two Quick Methods for Finding Shared Folders in Windows (use net share or compmgmt.msc) I like this one:

fsmgmt.msc

It directly gets you to the “Shared Folders” inside compmgmt.msc
