Stack Hash 64 bit version

Dear all,

My Windows Explorer is crashing regularly (mostly when scrolling down pics) and I am looking for a way to solve the issue. It's a StackHash Error, which I have tried to solve by creating a DEP exception, however since it's a 64 bit version this is not possible. Do you have any other idea how to solve the problem??? I post the error code here, however it's German.

Thanks a lot for any kind of support!!
