1. Press Windows + R, type “regedit.exe” (without the quotation marks) and press the ENTER key. If you see the User Account Control dialog box appear, click Continue

4. Below that key, you should see a 9.0 key. Select the 9.0 registry key.
5. In the right pane, make note of the number you see in the Data column for the row where the Name is set to (Default), in case you need to revert to this number later.
6. Look through the list of numbers in the Name column and find the highest number.
7. Double-click the (Default) string value to open the Edit String dialog box.
8. Replace the number in the "Value data" box with the highest number you saw in step #6. Click OK.
