Clarification Request
Which OS?

This is a common Windows log in issue but how it's worked varies with the OS.

Usually, It Means Your User Profile/Account Is Corrupted

Here, we simply log in to a second admin user which we always create as a backup, then create a new account with a new username with admin credentials and copy all important files from the corrupted user account to the new one. Once you're sure the new account is working well, simply delete the old, corrupted account.

Hope this helps.

He may need to...

...strip permissions off those files from the previous profile before they will work in a new profile. Easiest is to copy them first into an FAT32 formatted partition, then copy into the new profile. He may have a problem even accessing files in another profile in Windows 10.

Yep, But First He Has To Log In Somehow, Or...

Usually, I don't have problems copying the files from one account to another, as long as the new account has admin rights. Sometimes it's not that easy... But.... If there isn't a second admin user, then he may need to reinstall Windows after first getting his files off the machine using a boot disk. We'll see what the response is.

Hope this helps.

Not with ophcrack

More story needed.

Ophcrack is neat and all but if the user elected for an email login under W10 then I haven't seen this help.

I can't answer on that one

I was one of the Beta testers, promised a free W10 for doing it, and it seemed quite good on all those builds, but then they went to the Retail version and demanded an windows email login. I did that, and the profile I'd been using was lost, subsumed I guess into the email account profile. I then discovered they'd added a lot of spyware into it, which hadn't been in the beta versions. Later they admitted they'd locked a lot of beta testers out, supposedly by mistake and gave instructions on how to get the "free copy" even without using W7 to do so. By then I'd dropped it anyway since I already was using Linux instead for some years. I was no longer interested in it.
