What is linux equivalent of windows rstrui.exe command?

I am using old ophcrack cd to try to restore my XP computer that will not even start in safemode.    I do not know linux well.

What caused the mess was that I tried to set up the XP PC with a wireless USB connection and did something wrong. The PC was asking me for a password on an account that is never used. There never was a password on this PC i dont think. Anyway it wont strt any way I try. it will strt to a CD but that is all. F8 page appears but then asks for a password for 1st time EVER. I have spent 5 hours trying to get to restoration tools, restore console...anything. Anyone have aany ideas? thank you.

I have a new laptop that is connected wirelessly so i thought it would be easy with a a wireless usb adapter. Not so

Hi Guys, I am so sorry, but I fixed my own issue. However:

I will be back lots more. A long illness took me away from computing for quite a while. I am new to win 8.1 and i do not like it and I have lots of questions about my new laptop and wireless networks. (Not my Forte) For safety reasons, Wired connections are not allowed in this senior building and we are forced to use the Comcast's wireless Routers on a 150 person network that is much slower thatn the advertised speed we pay for. by contract with the buildings owners. Anyways i hope computing is like riding a bike after 4 years. But I think not. I am lost.
I answered my own question by using The 2009 CD version of "ERD COMMANDER" which allowed me to do a system restore and undo the wireless mess I made. System restore may do the job but I still do not know what I did wrong.  I am wireless ignorant.  I am used to a router and a 24 port ethernet switch...not a thing about wireless.
So thank you all for your time. With windows 10 coming and my age creeping up there, I will have lots of points for you folks On Expert's Exchange....The best help group of them all.  Thanks again and please accept my apology for taking your time. I thought I would contribute the knowledge of The ERD CD to the group as a great one to use for non-experts, in a jam on an older system.

I will not close this to allow someone to possibly tell me an alternative method to repair my mess, since i got lucky finding an ERD disk after 3 years and earn the points, if the rules allow that.

 I'll be back.

Whoops... Sorry we crossed in space.  No, I was unable to access the BIOs .  It kept asking for this unknown password.  It still looked like it was going to do so again after the system restore , but it was grayed out and I was fortunate enough to be able to click onto windows.

There are several password reset tools i.e. pogostick http://pogostick.net/~pnh/ntpasswd/cd140201.zip

now that you are into the system you can go to users  .. manage another account and delete the unknown account.  

You should create another administrative account just in case

If you can log into Windows XP and install software, download and install Cain (oxid.it) and that will allow you to extract the administrator password from the hash. It will look like p.a.s.s.w.o.r.d.

Cain is a legitimate tool and I can recommend it here.
