I passed that by because of the way you stated it:
A few of them would tend to be
HKLM-Software, HKCU-Software, and you mentioned classes so
HKCR.
"A few of them" tells me there are more.
Yes that's quite possible.
As I already wrote, the key to doing it is NOT what you are
doing, not trying to think on things.
The key is to actually do it.
Actually.
Not think, do.
You are spending hours "thinking" on things then telling us
you haven't the spare time to do what wouldn't have taken
this long.
As already written, this is a bulk process to get most
things working. Some may not work. Maybe you install 5
things again, or maybe you fire up sysinternal's regmon and
see that when you launch the app, it's trying to read a
particular registry entry, so you merely export that parent
key and merge it.
These are basic concepts, which take more time to think on,
than to do. You may not realize this, and that is why I
continually stress not doing what you are doing, which is
anything except the productive path to get it done. I have
been down this road and have advised what addresses your
expressed need, to have minimal time spent, while you
continue to do the opposite, making it the most drawn out
process possible.
Those phrases told me you were not sure, so I didn't take them as a
final statement.
Sure of what? I'm sure you need those keys and I'm sure
it's not guaranteed to make 100% of your apps work. This
was already written, that it is a bulk transfer to get the
majority working, then anything remaining will indicate what
to do next, whether it be more registry entries or files,
but each thing done in turn, NOT trying to do everything at
once is the key.
It is important NOT to do everything at once, because we are
trying to isolate the problem, not duplicate the old
installation perfectly which would naturally reproduce the
problem. Thus, the prudent approach is going to be a
conservative transferral of each type of setting, file, etc.
So what is your final statement about the Registry keys I must
transfer to make this new install work? Is your last statement
correct:
HKCU-software, HKLM- software, HK-Classes-Root.
Is that correct?
Yes, export each of these, but not merging them. Get new
installation working 100% first.
I have not done anything yet because I want to be certain what I am
going to do.
What you need to do is to NOT try to think ahead. It is a
fluid process and you may need adapt to what happens. For
instance, after merging registry keys you might launch an
app and get a message like vbrun*.dll not found (or
similar), meaning you need to install MS's visual basic
package.
So in this example, you might google search;
http://www.google.com/search?q=Windows+visual+basic+download
.... and the first hit is the page to download it, then
install.
Such things may happen, but it's not like you have to do it
for every app, one time and you have the visual basic
support.
Statements like
"A few of them" and "would tend to be" does not cut it with me. I
don't need a merry chase. I will try the "clean install" only when I
am confident that it will work.
Then don't.
You are the one with the problem, and you continue to spend
time, yours and ours, on it. This is the next step and it
doesn't matter if you like to do it, can forsee every step
in a process you are not trying to actually DO, or not,
because you only have 3 options left:
1) Live with the problem. Fine by us, it's not our system
but here you are trying to resolve it, so,
2) Do the clean install. As we've already told you, this
is not a matter of being forced to use the clean install for
your daily work, the clean install is a project done in your
spare time, until you are comfortable with it being finished
enough to revert to using it for your daily activities...
and until then you continue using the current problematic
installation.
3) Quit being so difficult and find an alternate point of
view in another forum. I'm not saying "go away", I'm
suggesting that a forum dedicated to WinXP or 2K might have
someone with more insight into the interworkings of NT/2K/XP
such that they might know a mechanism which causes these
phantom duplicate drive entries. That is, if nothing in
Disk Management is revealing. The stop being difficult part
pertains to DOing it- when someone makes a suggestion you
can't take the "I want comprehensive overview and guarantees
first", attitude, you'll have to take the "roll up sleeves
and try the suggestions", attitude. This should not be a
problem providing you are making backups as you'd claimed,
and must necessarily be doing if you are recovering from
this continual data corruption.
