Last known good configuration

[Guest]

One of the Safe Boot options is "Last known good configuration". When this
option is selected, what happens?

No, not really.

Looking in;
HKEY_LOCAL_MACHINE\SYSTEM\Select
you'll find the D_Word values for
"Current"=dword:00000001
"Default"=dword:00000001
"Failed"=dword:00000000
"LastKnownGood"=dword:00000002

CurrentControlSet is volatile and will always be an image (at boot) of
what's defined in ControlSetx where x = the value of "Current"

Choosing last known good boots the system with the control set that last
successfully booted your system. Control sets contain system configuration
information such as device drivers and services. Nothing in the software
hive.

It runs the last known good registry file.

There's no such thing.

Hi,

Choosing the Last Known Good Configuration startup option provides a way
to recover from problems such as a newly added driver that may be
incorrect for your hardware. It does not solve problems caused by
corrupted or missing drivers or files.
When you choose Last Known Good Configuration, only the information in
registry key HKLM\System\CurrentControlSet is restored. Any changes you
have made in other registry keys remain.

Hi Folks,

I note the following information from Bert:

If you have selected "Last Known Good Configuration", like I did, after
KB900485 did not allow me to reboot successfully, I wonder about the
following:

I won't be able to resolve the problem with KB900485 this evening
(basically because I don't know how to uninstall the failed install).

Is it safe for me to power off my PC? Will it boot up okay next time I
turn it on? Or will some other settings goof it up?

Thank you for your time.

Brad

I would suggest using System Restore to restore the revert the system
back to just before the update was installed. Run System Restore and
look for the restore point "Software Distribution Service 2.0" on the
date the update was installed. This will at least get you back to a
point when the system was functioning correctly.

Hi Bert,

Thank you for the info. Murphy's Law, we had a power failure while I
was at work, today. So, the computer needed to be rebooted. I was
pleased that it came up fine.

I went into Add/Remove Programs and removed the KB900485 update.
Cleaned up the system with Norton WinDoctor. Then after things were
spruced up I saved a restore point. Thank you for your webpage on the
procedure and warnings. Very helpful.

So, we appear to be good to go. I'm just ignoring the prompt for
updating that particular patch right now. Maybe this weekend I'll apply
it manually. Since I run Norton Systemworks 2006 I usually let Auto
Update alert me to what's new and I download them one at a time from
the MS site to install one at a time, with Norton's disabled.

Thanks, again.
Brad
