Vista Internet Explorer 8 Data Execution Prevention kills Internet Explorer 8 [closed]

"Steps to set up a DEP exception for IE8. I probably wouldn't just disable it for everyone, but if it's a trusted user:

Click Start, click Run, type sysdm.cpl, and then click OK.
On the Advanced tab, under Performance, click Settings.
On the Data Execution Prevention tab, use one of the following procedures:
Click Turn on DEP for essential Windows programs and services only to select the OptIn policy.
Click Turn on DEP for all programs and services except those I select to select the OptOut policy, and then click Add to add the programs that you do not want to use the DEP feature.
Click OK two times.
