LOST MY PASSWORD !
There are 5 levels of Passwords to lose. (more if using, "VeraCrypt" on anything)
One ploy is to own many paper books in large book shelf, and you Post-it is fully safe. (grin)
For casual (non financial)Online passwords (like forums or facebook, etc) use LASTPASS.(gee it's even free)
Store banking passwords only in your head, never write them down anywhere or on the actual PC in say a text file, that be a super bad idea.
Hard to read are these documents, UEFI and TPM, both are and endless dive in to A QUAGMIRE. ( for the simple users of PC's this is mostly Paranoia gone wild)
Better yet?, read your service manual at HP and see what BIOS security methods are enabled, and cures for lost low level passwords.
Or ask HP directly on their forum.
My laptop has a related issue, a finger print reader you will NOT get past, if you turn it on and this fails. (except HP direct help) (there is and INTEL "TXT" feature too , on some PC's that helps here.)
HP BIOS password resets. Best is not to use it. (if not doing CIA/NSA work, or other super secret work or other business or creative work, don't use it)
OLD PC's HP computers, had 2 jumpers on the mother board, named:
The relationship of UEFI and TPM is explained here by IBM , in one page.
BIOS used to be simple, and some PC's now have upto 8 updates just for UEFI, it's so buggy. (I say (1/2 joking) wait till 2020 when its bug free)
I own a Elitebook that the UEFI is half working, and will never be , full UEFI ever, (makes me happy)
The first step in this saga is to enter BIOS pages, F10 or ESC , (old /new PC) hammer the F10 key at power on, and see BIOS, then see if you can enter BIOS and get to the SECURE PAGE, if not the BIOS is locked with a password.
Some early PC one can reset this easy (2007 year) or is impossible, by the way , that is the GOAL here, the Impossible WORD !
#5 is HP direct intervention. (with a custom BINARY FILE) This is no by accident it is by Design, you turned it on, now forgot the PassWord and you or the BADGUY are blocked..
Here are the facts: (evolutionary) Each year more difficult.
A universally unique identifier is a 128-bit number used to identify information in computer systems. (kinda like the VIN number on cars , in USA but HUGE)
3.4028236692093846346337460743177e+38 , combo's (that is scientific notation)
Reads as a 3. with 38 zeros ofter it. in simple terms... no I'm not typing 38 zeros for anyone....ever.
(on your calc push 2 then the y/x key (below off key) then press 128 and enter. behold HUGE number,(Ti-30Xa- calc) also larger that Quadragintillion. used mostly for counting Atoms. and the like, 2n128 power.
Local Windows OS Password, I will not cover all 14 versions of windows. no.
Before Hacking , backup your data first !
The best hack we are told is the linux hack, using chntpw (change NT Password) works windows 8.1 and older. OS. (it just changes it and does not need to guess the old one first)
The offical statement from MS is to reload the OS, (after all would they teach how to steal other persons private data? answer, no!, why would the?)
Each year the OS get more difficult. (if running relic and dead, now, XP or VISTA use google to hack it, these old OS are child simple easy to hack. )
W7 has login screen exploit that allows manual hacking of 1 file to get ADMIN (cured in later releases, dig?)
W8 near same as above.
W10 , now things changed.
W10 was reEngineered to block such hacking (so they thought) It even hides the encrypted, code in secret place and then moves it time to time to prevent hacking. (BY DESIGN) but. but but...
But the hackers are smarter than MS, as it always seems? no? (warning MS may fix this method in future updates)
To boot a CD or USB memory stick , go into BIOS (esc key at power on) turn off "secure boot". or all this fails., the F9 key will not boot to, CD/DVD/mem sticks.
We then boot a live OS DVD or stick. (linux works best, it don't hide files) "Any live boot CD that allows file access, works"
The W10 hack is here. (no virus adding app tools )! (he is using Linux) One can use the free MS W10 install disk to gain, command prompt..
W10 hack site 2: see method 1, only (method 2 here is for CASH , Isee password disk, I'd never trust that ever)
I don't do hacks, but you can WEB SEARTH it. Windows 10 this is called the local Login and is not hackable. Reload W10 is the MS official cure.
Keep in mind if the HDD uses the MS or HP encryption feature, I bet all the above fails... (by design!)
The HP has F11 recovery partition that gains access to the installer and command prompt.
The Microsoft home page for W10 down load will burn any DVD or stick with W10 installer, (takes no retail COA key like W7 does, to DL it., so .... do that.)
The Microsoft live login , (if you said yes during the install) wille the Microsoft LIVE CLOUD login, to reset that , as millions have is there.
Cured only by going to microsoft live and doing request there. And this MS policy page.
If you down load many EXE files to hack your PC, you will get infected. (with a nasty PC virus)
This comments are only mine, and mine alone and are only OPINION. The real truth is all this STUFF varies by the year your PC was made.
