5. How do I delete old user Profiles?

User profiles are stored in C:\Users. There are special folders called Public and Default which must NOT be deleted as they contain the a shared profile for shared documents and a Default user profile used to create new accounts. Profiles can be deleted via the System Control Panel, select the Advanced tab and then User Profiles. You can copy or delete profiles here.

Create a new account and login with it, then copy the folders from your old profile into your new profile in C:\Users such as Application Data, Local Settings, Desktop, Favourites, My Documents, Send To, Start menu but not then ntuser.dat or ntuser.dat.log files.

A Power User has more permissions than a Standard User and can read/write to files in C:\Windows or C:\Program Files and make some system changes. This feature is not available in Home editions. In Professional or Ultimate, you just need to add the user to the Power Users group via the Computer Management console.

8. How do I customise the Default User?

The Default user profile is used when creating new accounts in Windows 7. It contains the default settings for all new accounts created on Windows machines. Usually, when you create a new account and login, the default user's settings are copied to the new profile, then the user can customise their setup as they wish. If you wish everyone to have the same settings from the start. You need to copy the settings to the default user. In Windows 7, you have to use the Administrator user for this. First, create a new user called NewAdmin, then login with it, logout. Login as administrator and then use the Control Panel to change the settings as you wish, change the My Documents location, Screen Savers, backdrops and so on. Then logout when done. Login as an NewAdmin user and load the System control panel, click on Advanced, user profile Settings and select the NewUser profile from list, click on Copy To and browse for C:\Users\Default and click ok to copy settings.

You can use your Password Reset Disk which you created when you first installed Windows 7 or when you created accounts to reset your password. To use the disk, boot up Windows 7 as normal, on the Welcome screen click your user and then click on the Question mark button, the Did you forget your password message appears, click use your password reset disk to start the Password Reset Wizard to set a new password.
If you do not have this disk or deleted your user, reboot in Safe Mode by pressing F8 during the boot up sequence and login with the built in Administrator user and use the User Control Panel to change your password or create a new user.
10. I have installed some programs but they do not appear in the Start menu when I login as another user?
For users to see program shortcuts they must be either copied to their Profile (C:\User\<user>\AppData\Roaming\Microsoft\Windows\Start menu\Programs) or in the ProgramData (c:\progradata\Microsoft\Windows\Start menu\Programs). If you install a program and the shortcuts do not appear in another user's account then you need to move the shortcuts from your profile to the ProgramData start menu location.
You can access either location quickly by right clicking the start menu icon at the bottom left and click either Open (or Explore) for your own program short cuts or Open all users for shared program short cuts.
11. Can I rename my profile folder in C:\Users?
It is possible unfortunately, a lot of Registry entries will point to files and folders in your Profile. It is better to backup your Profile to another directory, as an administrator user, (create one if you only have your own), login, goto System Control Panel, Advanced, User Profiles and select Copy To to copy it to another folder. Then delete your old user account (along with the old profile), create a new user, login as the new user to create a new profile. Then logout and login as an Administrator and copy the profile into your new Users folder.
12. I have some files, they are private and I cannot access them?
You need to grab Ownership of the file, this can be done via the Properties of the folder, click on Security, Advanced, Change Owner.
13. Can I move folders from C:\Users to another location?
Yes you can, the Documents folder is easiest to move, locate C:\Users\<username>\Documents folder on your hard disk, right click it and select Properties and select the Location tab enter a new directory and click Move.
The Temporary Internet Files can be relocated using the Internet Options control panel (see Settings, Move Folder). Other folders can be changed using a program called X-Setup or use Regedit and change locations in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ Explorer\ShellFolders. So you can move your Favourites, Cookies and Application Data etc elsewhere.
14. How do I change my password?
You can change it via the User Accounts control panel, the Computer Management console or sometimes via the Ctrl+Alt+Del screen and select Change Password. You can also use the Net user username new_password command to change passwords of a user.
15. How do I turn off or change the User Account Control dialogs?
You can change it in Control Panel, User Accounts and Family Safety, User Accounts and Change User Account Control Settings. Unlike Windows Vista there are now four levels to choose from:
a) Always notify (when installing software or when making Windows changes or settings).
b) Default. Only notify me when programs try to make changes to my computer.
c) Notify me only when programs try to make changes to my computer (do not dim the desktop)
d) Never notify me when installing programs or making changes to Windows.
16. How do I enable the built in Administrator account?

Net user administrator /active:yes . The account will then be available on the login screen when you logout.
