Safe Mode Password Issue (lost password)

Greetings all:

When I installed Windows on this system, I used a temporary password as my current one is a tad too difficult to use.
Once installed, I went to Live and Hotmail to change password.

However, now, a year onwards, I need to get into my Safe Mode here, but... it simply does NOT accept my new password, it demands my OLD one (the one used during setup).

Whomever figured that this was a clever move to bring this in, surely was a Joker, thinking that it was fun to pull this stunt.
Well, it's definitely not funny...

I have really no idea what the old password is 9as it was purely for the bloody setup), and I see tons of "change password" info that will reset my current one, but I cannot do this on this system.

In short: I need to get into my Safe Mode WITHOUT resetting my password all-over.
Is there a way to edit the old password into a new, simple one?
If so, just how do I do this WITHOUT thrashing my current password used on my system?

Thank you.

Another possibility:

I enabled the hidden administrator account, logged in as admin then rebooted into safe mode from the admin account. Logged out of admin and back into my user account, then disabled the admin account.

Just be sure to disable the admin account when you're done as it's not advisable to leave it active.

Thank you both.
The Admin Account one worked splendidly.

Thank you, @OldGuyFromCdn.
Totally forgot about Admin Account!

You're welcome.
