In this page, when we mention Windows Vista the some answers still apply in full to Windows 7 and to Windows Server 2008/2008R2

Q: What versions of Vista are supported by AWRC?

A: You can install AWRC on any edition of Windows Vista and later, and you can connect to computers running any edition of these operating systems.

Q: Does AWRC require Administrator privileges?

A: You do not need Administrator privileges on the machine where you install AWRC - you can launch and run the software as a Standard User.
However, "by default", you need to be a Real Administrator on the remote Vista machine for the connection to succeed because, "by default", Vista does not allow Filtered Administrators to connect through the Administrative shares (C$, ADMIN$, etc.). You can also connect as a Filtered Administrator by changing a single Registry key ( see below ).
Note: In Vista there are 2 classes of Administrators: Filtered Administrators and Real Administrators. The built-in Administrator account is set to be a Real Administrator account. Within a domain, Domain Administrators are as well set to be Real Administrators. In Vista, Real Administrators, behave like traditional Administrators did in previous Windows versions.

Q: How do I enable the Real Administrator Account on a Vista machine?

A: Proceed as follows (see also next question):
1- Click Start, then type secpol.msc in the Search box and click Enter.
2- In the left pane, choose Local Policies/Security Options
3- Set Accounts: Administrator account status to Enabled.
4- Set User Account Control: Admin Approval Mode for the Built-in Administrator account to Disabled.

Q: How do I enable the Real Administrator Account on Vista Home Premium and Starter editions?

A: Proceed as follows:
1. Click Start, and then type cmd in the Start Search box.
2. In the search results list, right-click Command Prompt, and then click Run as Administrator.
3. When you are prompted by User Account Control, click Continue.
4. At the command prompt, type net user administrator /active:yes, and then press <enter>.
5. Type net user administrator <Password>, and then press <enter>.
Note: Please replace the <Password> tag with the passwords which you want to set to the administrator account.
6. Type exit, and then press <enter>.

Q: Is it possible for Filtered Administrators to connect without disabling UAC (User Account Control) on the remote machine?

A: Yes, all you need is change (or add, if is not there, then change) a single key value in the Registry of the remote computer.
1- Click Start , then type regedit.exe in the Search box and <enter>.
2- Browse to HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Policies\ System
3- If it is not there, enter a new DWORD Value named LocalAccountTokenFilterPolicy
4- Set Value data of LocalAccountTokenFilterPolicy to 1
That's all.

Q: Why am I unable to connect to other remote computers?

A: Either within a local area network or across the Internet, AWRC requires Microsoft Networks to be operative - Client for Microsoft Networks installed on both local and remote machines and File and Printer sharing enabled at least on the remote machine.
Also access is only possible within the classical sharing and security model for local accounts. This is enabled from Control Panel / Administrative Tools / Local Security Policy / Local Policies /  Security Options / Network access: Classic - local users authenticate as themselves. You can obtain the same result from Windows Explorer / Tools / Folder Options / View and uncheck Use Sharing Wizard (Recommended). This will revert you to the classical model as well.

Q: Can DEP (Data Execution Prevention) cause connection failures?

A: Normally not, but if you feel connection problems try to change the DEP settings on the remote computer as follows:
1. Click Start
2. Select Control Panel
3. Select System
4. Click the Advanced Settings/Advanced tab
5. In the Performance region select Settings
6. Click the Data Execute tab
7. Click Turn on DEP for essential Windows programs and services only
8. Click Apply
9. Click Ok
10. Reboot

Note: By default some Windows Server editions, normally 64-bit, come with DEP turned on for all programs and services. You may either turn DEP on only for essential Windows programs and services (as explained above) or enter an exception for AWREXEC.EXE on the remote machine. If necessary enter also an exception for AWRC.EXE on the local machine. 

Q: How can I produce Ctrl+Alt+Del to logon to a remote Vista machine?

A: With AWRC 7.0 you can produce Ctrl+Alt+Del by pressing the corresponding hotkey (Ctrl+Alt+D by default). Earlier releases of AWRC had not this capability.
