Windows 7 Administrator password and privileges

[Vlodec]

I've just installed Windows 7 x64 Home Premium and it's a nightmare thanks to UAC. Things have finally come to a head now I've tried to delete a folder in Windows.Old only to be told I require permission from administrators. Things is, I'm the only user of this machine. I AM the administrator, or so I thought. Anyway, to cut a long story short I finally managed to bring up the actual Administrator account but find I can't log in to it because it requires a password. As I never supplied a password when I installed Win 7 I'm completely confounded by this. How on earth do I fix this problem ?

How to use the Disk Cleanup feature to delete the Windows.old folder

Thanks for the link, but the fundamental problem of the Administrator password remains. How on earth can there be a password when I didn't set one, and how can I fix it ? Does it imply a clean re-install of Windows ?

Let's proceed step-by-step:

1) Could you delete windows.old with disk cleanup ?
2)

but the fundamental problem of the Administrator password remains. How on earth can there be a password when I didn't set one, and how can I fix it ?

Have you tried to take ownership of windows.old, right-click the Windows.old folder, select Properties > Security Tab > Advanced at the bottom > Owner Tab > Edit > Highlight your username and put a tick in ‘Replace owner on subcontainers…’ and Apply > OK. ?
