Microsoft Vista, disabling UAC.

When changing some system settings, you are bombarded with
warnings as what you will see in illustration 1.
How does UAC protect us? Since the virus infects your computer
when you use it as a standard user, the virus cannot get access
to the global system resources, and therefore the amount of
damage it can do is severely limited. Although it still can corrupt
your documents and read your email, it cannot infect Windows
system files or install itself to be automatically activated every-
time you login to the computer. If a virus attempts to modify the
system files and settings, UAC will alert you by displaying an
elevation prompt.

I will not recommend this for normal user. If you are a season and
a advance user, here are ways whenyou can disable the UAC
function.

Important:
I will recommend that you to back-up you registry  before attempting this.

Microsoft Vista Ultimate, Business, and Enterprise
To disable the warning messages, use the following steps:

1. Click “Start->Run”.
2. In the dialog type “gpedit.msc” and press “Enter”.
3. In the “Local Policies” list, click “Security Options”.
4. Scroll down and double-click “User Account Control: Behavior
    of the elevation prompt for administrators in Admin Approval
    Mode”. The entire title may not appear in the window, so look
    for something that matches the beginning of the above option.
5. In the dialog, change the setting from “Prompt for Consent” to
    “Elevate without prompting”.
6. Click “OK” to accept your changes. Those annoying warning
    messages should now be disabled, but UAC will still be active.

Microsoft Vista Home and Premium

Other versions of Vista don’t include the Local Security Policy
tool, but there is another option you can use. To disable the UAC
warning messages, use the following steps:

1. Click “Start->Run”.
2. In the dialog type “regedit”, and press “Enter”.
3. Navigate to the following key:
    HKEY_LOCAL_MACHINE > Software > Microsoft >.
    Windows > CurrentVersion > Policies > System
4. On the right side, double-click the value “Consent Prompt
    Behaviour Admin”.
5. Change the value from “2″ to “0″ to disable the UAC warnings.

MS PowerPoint 2003/2007 .pptx unable to save to format .ppt

In PowerPoint 2007 or 2003 you try to open a PowerPoint file or to save a file in something other than the default format and see: you are attempting to save a file that is blocked by your registry policy.








Causes

This may occur because an administrator has deliberately changed settings that prohibit opening/saving certain file types in PowerPoint, or because of a change made by Service Pack 3 (S3) for Office 2003 or Post-SP3 hotfixes.

First, if you have Office 2003 and have just noticed this change in behavior, it's probably because SP3 has been applied.

In that case see this:
http://support.microsoft.com/kb/938810

Information about certain file types that are blocked after you install Office 2003 Service Pack 3

The page talks about making changes to the Registry. This can be complicated and may cause other problems on your computer if you make mistakes. But scroll down and you'll find files "to re-enable" the disabled formats. You can download them from Microsoft's Download Center and run them to fix the problem.

If you have Office 2007 or have 2003 but haven't applied SP3, try this page instead:
http://support.microsoft.com/kb/922847/en-us

You receive an error message when you try to open or to save a file type that was blocked by your registry policy settings in PowerPoint 2007 or in PowerPoint 2003

In any case you cannot do the following in PowerPoint 2007:

• Save a presentation in the PowerPoint 95 or earlier file formats

• Open files saved in PowerPoint 95 or earlier PowerPoint formats
