Windows 10 black screen and cannot boot after windows update 11.2017 – November 2017

Yesterday i’ve got system updates:

KB4048951
KB4048954
KB4049011

I shut down my computer. Today when i turn it on i’ve got error 0xc0000225. One of them killed my system.
My Windows 10 is 1703 Creators Update.

There is a new version 1709 Fall Creators Update.

To solve it you have to boot computer from usb or cd.
You can download newest image from Microsoft:
https://www.microsoft.com/software-download/windows10
If you have problem you can go to english version, then you can choose language for the iso:
https://www.microsoft.com/en-us/software-download/windows10ISO
For older compilations you have to search in the web.

First try to System Restore point

If that not help you have to run run command line and backup current system registry and thenrestore registry.
Copy from:
C:\Windows\System32\config\RegBack\system
to
C:\WINDOWS\system32\config\system
Commands:
ren C:\WINDOWS\system32\config\system system.bak
cp C:\Windows\System32\config\RegBack\system C:\WINDOWS\system32\config\

Reboot the PC.

Then i’ve got error 0xc0000001
\Windows\system32\drivers\acpi.sys

So boot again from USB and copy the acpu.sys or another file(be sure you have booted from correct version of windows x64 or x86):
Run command line in troubleshoting.
Copy acpi.sys from drive X – this is booted partition image from pendrive. (Or you can grab needed file from antoher computer and copy it from pendrive)
cp X:\Windows\System32\drivers\acpi.sys C:\WINDOWS\system32\drivers\

My computer is working. Enjoy if it helps you.

Windows 7 cannot run apps as admin by UAC prompt

I had a problem with running apps as admin on the administrators accounts (users in group administrators). But not only as admin, nothing happen on every UAC prompt when i click Yes to run. I cannot run any elevated application.

Some time ago i had set auto login on non admin user account via netplwiz.exe and when i disable auto login everything works fine!

Solution is: in netplwiz check box user must enter login and password.

EXT4-fs (sda): couldn’t mount RDWR because of unsupported optional features (400)

I could be happen on EXT3 or EXT2 too. This error mean that there is enabled file system feature that does not supported by kernel.

I’ve got an error when I make EXT4 partition with e2fsprogs (mkfs.ext4) newer then my kernel.

First solution is create ext4 with oldertools:

apt-get remove e2fslibs e2fsprogs

and install older.
Second solution is remove features does not supported by kernel.
To list features run :

tune2fs -l /dev/sdaX

I’ve got:
Filesystem features: has_journal ext_attr resize_inode dir_index filetype extent flex_bg sparse_super large_file huge_file dir_nlink extra_isize metadata_csum
To try figure it out which feature is not supported you can try run

fsck /dev/sdaX
e2fsck -pv /dev/sdaX
mount /dev/sdaX /mountpoint
dmesg | tail

Remove them one by one because after some you have to fix file system and do other things:

tune2fs -O ^flex_bg /dev/sdaX

do something try mount

tune2fs -O ^metadata_csum /dev/sdaX

do something try mount

tune2fs -O ^extra_isize /dev/sdaX

do something try mount

tune2fs -O ^dir_nlink /dev/sdaX

do something try mount
Do something I mean fsck and other things which will be listed after command.
Done :)

ETKA 7.5, 7.3, 7.4 error, hardlock uninstall & reinstall

Requirements

  • Install .NET 2.0 and .NET 4.0
  • Disable driver signing enforcement by allow testsigningpolicy, run CMD as admin and type:
    bcdedit.exe /set nointegritychecks ON
    bcdedit.exe /set TESTSIGNING ON

    Reboot.

  • Disable driver instalation from Windows Update (it will make faster)

First step

To solve below errors copy library LexHdl5.dll to “C:\Windows\System”
(not System32)

Error Returncode 5 – Error H7!

Error when update Returncode 2 – Error AA!

Second step

The new enhanced graphical functions of ETKA couldn’t be used! (Error 3)

Run CMD as admin and go to ETKA directory RosyVisionControl:

cd /d C:\ETKA\VWAU\RosyVisionControl
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe RoSyVisionCom.dll /unregister
%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe RoSyVisionCom.dll /codebase
%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\regasm.exe RoSyVisionCom.dll /unregister

Hardlock Reinstall

 

Error 7 : Hardlock wurde nicht gefunden.

If you have any problem with devices  Safenet or something you should remove hardlock an install it again.

To reinstall hardlock you have to remove it. It is pretty hard to do that. You can check all services and drivers installed in your system with program called: Hardlock Diagnostic Tool  : diagnostix.zip (to delete service run sc in CMD). Download page: http://www3.safenet-inc.com/support/hardlock/downloads.aspx

Hardlock Uninstall

But there is a command line tool: Sentinel HASP Run-time Command-line Installation  – Sentinel_LDK_Run-time_cmd_line.zip that will allow remove all. Go to download page: http://www3.safenet-inc.com/support/hardlock/index.aspx

Unzip. Set compatibility mode Windows 7 and run as admin for file: haspdinst.exe.
Create shortcut to haspdinst.exe with switches:
haspdinst.exe -fr -kp -fss

It will remove Hardlock services and servers hasp. Reboot pc.

Then you can install hardlock properly.

Proper installation of HardLock
  1. Run 0000750A.reg from multikey.
  2. Run CMD as admin and go to multikey dir (check what is you system need x86 or x64) and install device:
    cd /d D:\MULTIKEY64
    devcon remove root\multikey
    devcon install multikey.inf root\multikey
  3. Allow to install unsigned driver. Wait for device installation in device manager at System deivces:
    Virtual USB multikey
    root\multikeySeriously you should wait to automatic installation. It can take a long  time of you didnt disable windows update drivers installation.
  4. Install hardlock.exe and wait for automatic installation of 2 devices at universal serial bus:
    SafeNet Inc. Hardlock Key
    USB\Hardlock
    SafeNet Inc. USB Key

    USB\VID_0529&PID_0001&Rev_0321
  5. Done.
