I purchased a new Dell computer with Windows Vista Home Premium and set it up
a couple of weeks ago. I use the computer at home and use a dial-up service.
It was working fine until today when I tried to logon and was unable to
logon. This message kept appearing:

The User Profile Service service failed the logon. User profile service
cannot be loaded.

I saw another discussion item along this line, but I am not entirely sure
how to follow it. The person referred to F8 and using a safe mode. Can
someone explain it in a litttle more detail for someone who is not a computer
guru? Thanks.

When you first press your start button (power button on the machine) right
before any windows related messages appear, press F12 button. For a brief
moment you should actually see: F2 - something and F12 - boot menu.
You may actually try to do it a few times if you missed the moment. Also I
am not
quite sure if it is F8, most likely it is F12 - boot menu.
You will get a black screen with a few options. You will have to select them
with UP and Down arrows. There will be an options Run In Safe Mode. Click
it.

It takes some time to navigate through subsequent instructions because
people who write them usually lapse in technical slang that creates
ambiguities in a lay mind. But it is doable.

Alex,

Thanks for your detail reply. I will try the procedure and hope that it
works.

I've just had this problem on my computer, and I just fixed it.
It seems to be caused by a horrendous bug in Vista that renames your User
Account Profile as a backup, and then creates a new user account with the
same name but with nothing in it.
I googled it and followed several bits of advice but none of them worked,
but I managed to fix it with a combination of ideas.
This is how I did it:

1. Boot up in Safe Mode. To do this, hit the F8 key while the computer is
booting, and then scroll down to the "Safe Mode" option and press enter. On
my computer the user account icon appeared, but bigger than normal, and I
clicked it and it loaded my desktop in safe mode. It came up with an error
bubble saying that my user account hadn't loaded properly, but i just ignored
this.

2. Click the Start Button and in the white "Start Search" space at the
bottom type "regedit" (without the quotation marks). This will open the
registry editor.

3. In the left-hand pane, navigate by clicking the little triangles next to
the following folders:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Windows NT
CurrentVersion
ProfileList

You should now have a list of folders all starting with S-1-5- and then a
number.
(You might need to drag the divider between the 2 panes of the window across
so you can read the whole folder name)
Look at the end of each name and you should see one with .bak at the end of
it, and there will be another one above it with exactly the same name but
without .bak at the end.
The one that's got .bak at the end is your old User Profile that Vista has
now made into a backup, and the one without .bak after it is the new empty
User Profile that Vista has created.
Just to check that this is the case, have a look in the right-hand pane for
each of the 2 folders and look at what's written after "ProfileImagePath".
For the folder with .bak at the end it should say C:\Users\ and then your
usual User Account name, and for the one that doesn't have .bak at the end it
should say C:\Users\TEMP.

What you need to do now is to rename the folders in the left-hand pane so
that the one with .bak at the end changes back to being the one containing
your proper User Profile and the new one without .bak at the end becomes the
backup. Do do this follow the next step:

4. Right click on the folder with .bak at the end and then click "rename",
and just change the ".bak" part to ".bk" - i.e. just remove the "a" from the
middle - (this is just to allow you to change the other one to have .bak at
the end). Press enter or click on some blank part of the screen for the
change to take effect.
Then, right click the one that doesn't have .bak at the end and click
"rename". Remove the .bak from the end and press enter or click anywhere on
some blank part of the screen to accept the change.
Then, right click on the one that now has .bk at the end, choose "rename"
and add the "a" back into the middle, so it now has .bak at the end. Press
enter or click on blank park of screen to accept the change.
Close the regedit window.

5. Click the Start Button and then "Restart". It should work now. Fingers
crossed. :)

I'd like to thank you for helping me fix my problem after searching some
ineffective info other over and over again.

hi
am i reading this fix correctly?
point 4
change .bak to .bk
then click one that doesn't have .bak then remove .bak?
then change the one with bk to .bak

how can i remove .bak if it doesn't have it? and if I am supposed to
add it then but files would end up the same after changing .bk back to
.bak?

sorry to be a dumb wit but I want to be clear before i start this fix
as I am allways nervous with thing like this that I know nothing about.
many thanks

As you say, those instructions don't look exactly correct, but I'd suspect
that the bigger picture is that you are essentially swapping the one that
doesn't end in 'bak' with the one that does, via a 'bk middleman'.


In other words, let's say you have 2 files or folders

a
a.bak

and you want to swap their names

You can either go

1. a >> a.bk
2. a.bak >> a
3. a.bk >> a.bak

OR

1. a.bak >> a.bk
2. a >> a.bak
3. a.bk >> a



It's like having a glass of orange juice and a glass of lemonade, and
wanting to transfer the contents of one to the other, using a spare third
glass. You could tip the lemonade first into the spare, and then the orange
juice to the emptied lemonade glass, and then finally from the
lemonade-filled spare into the other. OR you could start by pouring the
orange juice into the spare ....


Not sure if that makes matters clearer, or just makes you thirstier, but
hope it helps anyway.

The .bak part is as follows... you basically want to delete the .bak
from the one that has it and put it on the otherone. then take the first
.bak off. In order to do that you need to rename the file that has the
.bak to .bk (this is done as described in the previous instructions...
right mouse click, choose rename, click on the end of the file name and
delete the 'a' from .bak to become .bk, then hit the screen anywhere to
lock in the name change).

Next go to the file without the .bak and rename that to include a .bak
(follow most of the rename instructions above to add the new .bak. Click
on the screen to lock in the change.)

Finally go to the first file you were working on and rename it again to
remove the .bk so there is no extension. This becomes the correct
profile to start up.

Once that is done, you can restart your computer and see if it works.
Good luck. His instructions worked beautifully for me with this minor
.bak difference.

Huge respect to Marek for the excellent solution. I had a similar
experience today which looked unsolvable until I read this post.

The instructions were fine and it worked first time. This post should
be preserved at all costs.

Many many thanks.

Help! I've followed Mareks geat instructions but the system won't allow
me to change the files. I'm assuming that it's because the User that's
faulty is ADMIN! Can anyone offer any help please?
