Windows: force a CHKDSK of a non system disk at boot time

Posted by jpluimers on 2019/03/22

Just out of curiosity, I wanted to try run a CHKDSK at boot time of a non-system disk.

The trick appears to be to ensure something locks the drive. An easy way to do that is have a command prompt open inside a directory on that drive.

The below example show just that: a regular command prompt locking the E: drive and an administrative command prompt scheduling the check at boot time:

In text

Regular command prompt:

Microsoft Windows [Version 10.0.15063]
(c) 2017 Microsoft Corporation. All rights reserved.

C:\Users\jeroenp>e:

E:\>cd $RECYCLE.BIN

E:\$RECYCLE.BIN>

Administrative command prompt:

C:\WINDOWS\system32>chkdsk /R /F E:
The type of the file system is NTFS.

Chkdsk cannot run because the volume is in use by another
process.  Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) n

Chkdsk cannot run because the volume is in use by another
process.  Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N) y

This volume will be checked the next time the system restarts.

C:\WINDOWS\system32>

List of Shell GUIDs for various Windows versions for use in shortcuts and batch files

Posted by jpluimers on 2019/01/09

In my search for starting the Windows Credential Manager from the console, I found [WayBackCredential Manager Shortcut – Create – Windows 7 Help Forums explaining:

%windir%\explorer.exe shell:::{1206F5F1-0569-412C-8FEC-3204630DFB70}

This reminded me of From batch file or shortcut: start Windows Update (via: Windows 7 Help Forums) and batch-file trick: Starting Windows Explorer and selecting a file (“explorer” commandline parameters “/n” “/e” “/select” “/root” “/start” site:microsoft.com).

The odd thing is that some of the GUID shortcuts works fine using the shell::: syntax, but fail with the /e:: syntax, for instance Windows Update until Windows 8.1:

%windir%\explorer.exe shell:::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}
%windir%\explorer.exe /e,::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}

One day I’ll create a table of permutations for various Windows versions and execute options.

For now these links need to suffice:

Adding Windows machines to Samba domains and security

Posted by jpluimers on 2018/12/07

If adding a Windows machine to a Samba domain fails and the below “solves” your issue, then you need to tighten the security on the Samba side:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters]
; Enable NT-Domain compatibility mode
; Default:
; [value not present]
; "DomainCompatibilityMode"=-
"DomainCompatibilityMode"=dword:00000001

; Disable required DNS name resolution
; Default:
; [value not present]
; "DNSNameResolutionRequired"=-
"DNSNameResolutionRequired"=dword:00000000


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters]
; Disable requirement of signed communication
; My Samba (3.0.33) works with signed communication enabled, so no need to disable it.
; Default:
; "RequireSignOrSeal"=dword:00000001
; Disable the usage of strong keys
; Default:
; "RequireStrongKey"=dword:00000001
"RequireStrongKey"=dword:00000000

Saving windows command prompt history to a file – Charlie Arehart’s ColdFusion Troubleshooting Blog

Posted by jpluimers on 2018/11/14

Dumping the command prompt history

From [WayBackSaving windows command prompt history to a file – Charlie Arehart’s ColdFusion Troubleshooting Blog:

doskey /history

gives you the command history.

Redirecting with >, >> or piping with | allows you to save this to a file or filter the output.

Found via: [WayBackHow I can export the history of my commands in Windows(7) Command Prompt? – Stack Overflow

Shells that do support persistent history

Note that the command history is not persistent. If you want that, then there are two other shells that support persistent history:

Both of these found through [WayBackwindows – Is there a global, persistent CMD history? – Server Fault.

DISM fix for Windows 8.1 high CPU usage of TiWorker.exe

Posted by jpluimers on 2018/07/27

This worked for Windows 8.1 as well: Trying fix for Windows 8 high CPU usage of TiWorker.exe (via: bit-tech.net) « The Wiert Corner – irregular stream of stuff

DISM /online /cleanup-image /restorehealth

 

After more than one hour of running, it:

  • freed up more than a gigabyte of disk space. Which on an SSD based VM is a lot.
  • solved the huge memory footprint of TiWorker.exe on the right.
