Removal Of Windows Vista

I have my sister's laptop which runs Windows Vista. I would like to remove Windows Vista and install something better like Win. 7 or Win. 8. This laptop has a virus and it won't connect to the Internet via wifi. I do know her user name and password. I tried the F8 button, but when it asked me to sign in as a user, I couldn't. I'm not a user. I typed in her name and password and nothing. This is why I want to remove Vista and install something else. I don't have the money to repair the laptop so I'm thinking a new OS might be the answer. Where can I get a new OS cd with the product key at an affordable price? I know Amazon has them, but what I e see, they are not affordable either. Any suggestions are greatly appreciated

 

If your sister knew her log in details to tell you, the system could be repaired, for the time being, by downloading the various tools on another clean system, then save them to a USB pen drive or DVD-R disk. The 'Read and Run Me First Guide' in the Malware Removal forum describes what tools you need for VISTA.
IF you can do that, then the experts on the Malware Removal Forum could guide you further.

 

MasterJedi, could you link us to the other sites you've posted this so that we don't waste time duplicating suggestions, please?

 

I posted this on Microsoft.com and still no reply

Another thing, the recovery CDs for Win. Vista, she threw them out.

 

There was a reply there when I posted. Can you work through the suggestions there first, please?

 

I'm doing it now. I'm running the antivirus software. It hadn't run in ages. The Rkill thing can't do it because I can't connect to the Internet. I do have the Ethernet cable. I'll have to look up on how to connect via Ethernet

 

Ran antivirus and Antimalware like they told me to do on the Microsoft website. I'll do the Ethernet thing tomorrow. Hopefully I can get on the net that way.

 

You should not post anything else here in this software forum.
You can now choose whether to carry out the steps in the
READ & RUN ME FIRST Malware Removal Guide
When you have completed all the steps you can, you can decide to start a new thread in the:
Malware Removal Forum
In that forum (not here) a trained malware expert will guide you further.
You should only follow one set of instructions, not on two different forums.
You have to choose to get help here or on that other forum. Not both.
