permissions

(Ignoring the irony of your name)

Right click on the root of the drive, Properties, Security, Advanced, Owner, Edit

Check "Replace owner on subcontainers and object"s then set the owner to you - beware, this will usually take a while to apply.

i tried the right click take ownership i get access denied

why am i gettting denied access while applying the ownership

You must be an administrator to do so, if you are not then contact your administrator and ask them for access.
Is there a specific reason you need ownership? All files you care about should be accessible (unless you have done an upgrade, when some may have not had the permissions transferred correctly)

I am the admin the only account on the comp

i want full access to all my files

You should already have full access to your files, any ones that you can't access there is a good reason for it (the only folder I can remember that you can't is System Volume Information, just because it's a little touchy to outside modification.)

The permissions on the windows disk and folder are there for a reason, to stop things getting broken.
