authentication – Bypassing Windows 10 password with Utilman.exe trick – fixed? – Information Security Stack Exchange

Posted by jpluimers on 2021/05/03

It is debatable if these tricks are vulnerabilities or not: [WayBack] authentication – Bypassing Windows 10 password with Utilman.exe trick – fixed? – Information Security Stack Exchange.

There are arguments that leaving a system open to physical access or allow operating system manipulation, it means it is busted.

On the other hand, making systems more resilient to modification, helps alleviate these problems.

So it pays for developers to harden operating systems against modification.

From the question:

Of the sethc.exe, Utilman.exe, and osk.exe ones in Windows, Utilman.exe seems to have been fixed.

How to remove (disable or hide) User Accounts on the Windows 10 Login Screen – Make Tech Easier

Posted by jpluimers on 2021/01/11

Works on my systems too (I think it works from Windows XP on) to hide users from the home screen: [WayBackHow to Hide User Accounts on the Windows 10 Login Screen – Make Tech Easier.

Show only the last logged on user, but add a switch-user dialog

Run the below .reg file on your machine, or manually add this key (does not need any value): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\DomainStyleLogon

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\DomainStyleLogon]

Note the empty line at the end of the .reg file: that is by intention.

This will show the last logged-on user on the home screen, but still allows users to perform a switch to other users.

Disable the users on the logon screen from interactive logon

Warning: do NOT disable your administrator user this way!

For why not, see the various users that lost access: [WayBackHide User Accounts on Windows 7 Logon – Windows 7 IT Pro > Windows 7 User Interface

  1. use net user on the command prompt to list the usernames and note the username you want to hide from the login screen
  2. run regedit to edit the registry
  3. ensure this registry key exists HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
  4. Under that key, create a new key SpecialAccounts
  5. Under the SpecialAccounts key, create a new key UserList
  6. Under the UserList key, create a new DWORD (32-bit) value with the Value name equal to the username and the Value data to zero (0, which is the default)
  7. Reboot
  8. Observe that user is not on the login window any more.

Example:

If you lost access because of SpecialAccounts

If you would like to unhide the hidden Administrator account on Windows 7:

  1. Boot a Windows 7 Installation DVD or ISO
  2. go to command prompt and type regedit -it
  3. click on HKLM hive and
  4. next navigate File>>Load hive
  5. navigate to C:\Windows\System32\config folder and choose `SOFTWARE` file load it and assign this hive any name for example REM_SOFTWARE
  6. open key HKEY_LOCAL_MACHINE\REM_SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList
  7. remove the Administrator account
    • or better way remove the whole key HKEY_LOCAL_MACHINE\REM_SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts

RDP logon while other user is logged on: no way to automate automatic disconnect/logoff

Posted by jpluimers on 2020/10/21

One of the dreaded things when logging on using RDP is that if another user is logged on, you have to first indicate you want to indeed logon (if you don’t, the RDP connection will close after some 15-30 seconds), then wait for their approval time-out before you can logon.

As of writing there is no way around this.

Some links that helped me conclude this:

Windows 7 Blue Screen Of Death with error 0x7B – twm’s blog

Posted by jpluimers on 2020/09/28

[WayBack] Windows 7 Blue Screen Of Death with error 0x7B – twm’s blog:

To allow Windows 7 to boot in IDE as well as AHCI mode, I had to enable the following drivers (by setting “Start” to “0” in the registry, there might be other options to do this):

HKLM\System\CurrentControlSet\services\intelide
HKLM\System\CurrentControlSet\services\pciide
HKLM\System\CurrentControlSet\services\msahci
HKLM\System\CurrentControlSet\services\iastorV

The first two allow Windows 7 to boot from SATA in IDE mode. The second two allow Windows 7 to boot from SATA in AHCI mode.
