How to access the Registry

Hi Adham,

Thank you for posting your query in Microsoft Community.

Some legitimate applications require a full administrator access token to perform their functions or tasks. The User Account Control (UAC) message is displayed to request consent or credentials to allow an application to use the full administrator access token in any of the following circumstances:

• The application developer marked the application to require an administrator access token. This is done by using a development technique known as an embedded manifest.
• UAC detected that the application is an installer or setup application. (Automatic detection can be disabled by using Group Policy.)
• Microsoft analyzed the application and provided an application compatibility shim. A shim is a small amount of extra code provided by Microsoft that supports certain non-Microsoft applications.
• An administrator configured the application compatibility settings on the application's Program Properties page.
• An interactive user right-clicked the application and then clicked Run as administrator to start the application.

All of these settings except Run as administrator apply every time the application is started. To occasionally run an application with a full administrator access token, use the following procedure.

To perform this procedure, you must be logged on as a local administrator or provide the credentials of a member of the local Administrators group.

Referemce: Turn User Account Control on or off

To run an application one time with a full administrator access token

1. Locate the program icon or a shortcut in Windows Explorer.
2. Right-click the program icon or shortcut, and then click Run as administrator.
3. When the UAC message is displayed, do one of the following:
   • If you are logged on as a standard user, or if UAC is configured to always require credentials, enter the appropriate administrative credentials, and then click OK.
   • If you are logged on as an administrator and UAC is not configured to always require credentials, click Yes to start the application.

If the above does not help, you may try installing the program in compatibility mode and check.

Please refer to: Make older programs run in this version of Windows

Windows 10 installation:

Since the installation process seems stable after disabling the security software, you may want to remove it and check if the installation process completes.

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.

This certainly restored the right sizes of the words. However, I think there must still be something wrong because:

a) Windows 7 doesn't appear in the list of OS options, and

b) when the program opens there's an update now or later option, but the update doesn't work. However, cancelling that window leads into the program and all the functions seem to be operational.

Thank you for your input. Very helpful.

My HD has three drives:

Local Disk (C:)

RECOVERY (D:)

HP_TOOLS (E:)

But in System Protection the available drives are listed as:

Available Drives                              Protection

Local Disk (C:) (System)                   On

RECOVERY (D:)                                Off

(C:) (Missing)                                   On

Both the drives and the protections look as if they're wrong. Are they?

And if I switch on the protection for D:, what might I lose?

On a separate point:

Is it my imagination or was the Set Restore Point facility available in Backup and Restore? If so, it isn't now.

Another issue is that in the Backup and Restore tab, it says "Windows Backup has not been set up". I can't remember now whether or not I had set it up before the Windows 10 downgrade, but when I click on Set up Backup, it offers two destinations: the DVD drive and the RECOVERY (D:) drive which has a mere 16.62 GB total size. This looks wrong.

Thank you for any advice or suggestions.
