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

Oh, okay, will do that. Thanks for your fast response!

I finally found out the problem with my pc. I was using a program called advanced system care, and when the program tried to defrag a particular file, it simply crashed, and I had to do a recovery (luckily I could backup my files in time). I found out because after the recovery, I downloaded again (thinking that it could identify a remanescent virus), but the computer crashed again. Note to self: ASC never again.

If there is a default user profile (unhide your hidden folders), delete the temporary internet files and any files in the temp folder ( close example: c:\users\default\appdata\local\microsoft\windows\temporary internet files)

This has worked many times!!! Cheers.

Hi guys, don't worry too much. Just restart your computer in 'Safe Mode'. Go to Accessories>System Tools>System Restore, and restore your computer for a recent restore point. That's all.

This is exactly the cause of the issue I was experiencing with a PC on a domain. Microsoft simply say "log in with another user account", yeah of course why didn't I think of that? Numpties!

Anyway my issue was a security/permissions issue with a file called iesqmdata_setup0.sqm in the directory C:\Users\Default\AppData\Local\Microsoft\Windows\Temporary Internet Files\SQM. By browsing to the machine remotely via the "$ share" method I changed the permissions on the enclosing folder to everyone and I was able to log in.

Very strange error but thank you for pointing me in the right direction!

Recently, I did an update which included a Toshiba update. After rebooting the system, I discovered my computer was having some dynamic library errors or something which were annoying because I did not know where they originated from. So the next thing I did was do a system restore back to prior of the update and the problem appeared to have go away.

About a week later I discovered the errors reappeared and since I do a data file backup on my partitioned E: drive with Macrium Reflect and a Macrium differential system image backup of my C: drive each week, I decided to restore the latest C: drive image.

Well, that is where my problems continued, my profile appears to have gone only to have a temporary user account. I read your post Brink Fix "The User Profile Service failed the logon. User profile cannot be loaded." Error in Windows 7, but after rebooting my Laptop, I get the same problem with a message "Preparing your Desktop" and "You have been logged on with a temporary Profile. You cannot access your files and files created in this profile will be deleted when you log off. To fix this, log off and try logging on later. Please see the event log for details or contact your system administrator."

Having edited the Profilelist as per instructions, after rebooting, the system ignores the edited ProfileImagePath of E:\Users\my user name but adds .bak to the S-1-5-21- line, creates another line with ProfileImagePath with C:\Users\TEMP.Qosmio.000.

In addition to this, I cannot see my partitioned E:\Data however, I have discovered through administrative Tools/Computer Management/Disk Management the partition is there, files are in tacked but the has NO DRIVE LETTER and I am unable to assign one.

What have I done wrong? Should I have restored the full image backup then the latest differential backup? It would appear that all my system files are in tack, my user name is there but I am not sure what has happened with my profile and or why I cannot access my partitioned E:\ data.

Thank you in advance.

Having given this further thought, my frustration got the better of me. The problem I think was due to net being able to see my partition drive E, where my user profile is. I found I could do very little with the partition except delete it which I did, recreated the partition, named it and assigned the letter E. Rebooted the system and could read it so I restored my data which will take a few hours.

What mystifies me though is why I could not see the partition E:\ after restoring C drive image file. There was a Microsoft command I used when I partitioned the drive so that user names were on the E partition and the system placed a shortcut on C:\username\me directing the system to E:\usernames but since E drive could not be recognized, she spat the dummy. We will see what happens after the restore!
