Windows 7 asks you for elevation of access rights through the User Accounts Control (UAC) dialog, when you try to make any changes to system files or install a program. By default, the UAC dialog is shown on a second secure desktop window. This way other programs cannot send programmed keystrokes to the UAC dialog and automatically grant elevated permissions. But switching to the second secure desktop is annoying and can hang some media applications like DScaler. If you want, then you can easily disable this switching of UAC to secure desktop for elevation permissions. Here is how :
- Press the key combination Windows logo key + R on your keyboard to open the Run dialog.
- In the Run dialog, type gpedit.msc and press Enter to open the Group Policy Editor.
- In the Group Policy Editor, navigate to Computer Configuration → Windows Settings → Security Settings → Local Policies → Security Options.
- Double-click on this entry and change the setting to Disabled as shown.
- Click OK to save the setting. You do not have to restart the computer, the changes take effect immediately.
