После использования непроверенных Чистильщиков Реестра, пропали многие Программы (файлы *.exe). Да ещё при запуске Компьютера стало появляться предупреждение - Крестик в красном

NT_Kernel error 1256

Неприятно. Надо переинсталлировать Windows, но в новой системе - XP - боязно

Как-то переинсталлировал - весь диск отформатировался (пол-года назад). Утеряна масса информации

Решил в Интернете сделать запрос по САБЖ
Косметически помогло это:

After reading all the various posts and since I have a machine that had most if not all the symptoms here is what I documented on how I completely cleaned this system:All,

I had ticket EDITED assigned to me, user was stating that she was getting the following popup error message with every boot-up:

During a scan of files at system startup, potential errors in the system registry were found.
p-07-0100 irql: 1f SYSVER 0xff0024
NT_Kernel error 1256
KMODE_EXCEPTION_NOT_HANDLED

and then this after 10-15 minutes:

A potential problem has been detected and Windows has been shutdown buggy application to prevent damage to your computer.
****WXYZ.SYS - Address F73120AE base at C00000, DateStamp 36b072A3
Kernel Debugger Using: COM2 (Port0x28f, Baud rat 192000)"

The user had two new icons on her desktop, Windows XP's "Help and Support" icon and Windows XP's "Windows Update", both pointing to storageprotector.com. Symptoms of this infection included sluggishness, inability to double-click "My computer" icon as well as others, depending of the configuration of the system.

I googled the NT_Kernel error 1256 and came upon the forum forum.bitdefender.com/index.php?showtopic=3561 and after combing through the forum I found a fix mentioned called FixVundo.exe. I have it saved at EDITED for easy access. I downloaded this third-party utility and ran it. It detected several .dlls related to this trojan and deleted all of them except one. The system required a reboot. Once rebooted, it deleted the final .dll and rebooted again and all icons on the desktop were now accessible. However, a new error message popped up wanting to run one of the affected .dll but was unable to locate it. The two malicious icons on the desktop also remained. Working with EDITED, the icons were deleted. Also, after double-clicking the "My Computer" icon, the C: drive icon was replaced with a big red X. After double-clicking the C: icon, roughly 4000+ .tmp files, all starting with the name posxxx.dll were in the root. I highlighted and deleted those files.

With EDITED help, we went into registry editor and went to HKEY_LOCAL_MACHINE\HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and deleted the .dll in that group. We then went to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer and found a folder called DriveIcon. We deleted it and refreshed the My Computer folder which brought back the default icon for the C:.

I then ran McAfee's On-Demand scan for good measure as well as deleted temp files and cookies. This system is now functioning normally.

Hope this helps!

Запустил программу VundoFix, поудалял то, что она обнаружила (с 2-3 раз, но одна осталась неудалённой)
Почистил Реестр там, где указано в статье

Ошибки нет.
Приятно

Но WindowsInstaller так и не восстановился.
Не могу инсталлировать (или вернуть к жизни) многие программы
