Win7 graphics hardware acceleration gray is not available solution

WIN7 graphics hardware acceleration settings do not need to be explained again, I really do not know if you can refer to:
win7 graphics hardware acceleration how to open
in the troubleshooting here [change settings] button is gray can not be set .

In fact, to solve the problem, the [Change Settings] button is not available. It is not difficult to replace the deskadp.dll, deskmon.dll, deskperf.dll provided at the bottom of this article. The three corresponding files in the /system32 folder can be used to turn on the adjustment hardware acceleration option. That is no longer "grey" & rdquo;
However, not all win7 have right-click "administrator ownership" & rdquo; this option, (for unknown reasons), first download the following compressed package file An import .reg, double-click to import directly to get administrator privileges, of course, it is best to back up your registry first (although I am very safe every time). After importing, find the three dll files mentioned above in system32, right click and select “Administrator Takes Ownership” and then replace the three dll files provided below. Once you're done, you'll be able to see the troubleshooting settings here.
