According a post by another Community Advisor installing as service (uninstall and reinstall) without the BOINC autostart option allows it to run without Windows Defender protests. The price is getting no graphics, but that can be overcome by exiting the BOINC service and manually starting BOINCmgr (with the UAC alert). Booting would restart the service. Also, the BOINC core client will run even if no-one has signed in or all users sign out.

Further, the shut-down of Vista with a service install does away with the "too fast" closing damage to work units if using the 5.10.30 version. With single user install and signing out the damage still occurs.

If Vista final service pack 1 is released that experience may change. Reading of BSODs with Vista SP1 RC1, not going to try and find out.

"User Account Control (UAC) is a new security feature in Windows Vista that requires all users to log on and run in standard user privileges mode instead of as administrator with full administrative rights, thus prevent unauthorized or accidental changes that could destabilize the computers or allows virus and malware to exploit the system-level privileges provided to the local administrator to attack the network security, compromise computer safety and privacy, and damage files and settings in the network."

There are a few ways that you can use to turn off the UAC, but most home and personal users should find method to disable UAC via Control Panel easiest to do.

Method 1 - Using Control Panel

1. Click Start and then open Control Panel.
2. In the Control Panel, click User Accounts and Family Safety.
3. Click User Accounts.
4. Click Turn User Account Control on or off.

It looks like a future version of BOINC might need to turn off the UAC upon installation.

Method 3 - Using Registry Editor

1. Run Registry Editor by typing “regedit” in Start Search or command prompt.
2. In Registry Editor, navigate to the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Policies\System
3. Locate the following DWORD registry subkey in the right pane:

EnableLUA
4. Right click and choose modify or double click on EnableLUA to modify the setting. On valud prompt, set the new value to 0.
5. Exit from Registry Editor.
6. Restart the computer.
7. To enable the UAC again, simply change back the value of EnableLUA to 1.
