CCleaner finds the following entry checking my registry. I copied it to a text file:
Open with Application Issue "C:\WINDOWS\System32\drivers\Win7UI.exe" %1 %2
I cannot find an entry in C:\ at all but in the registry I find the entry. In CCleaner, I have this issue fixed, but after each cold or warm start it turns up again. Deleting the registry part directly does not help either. It turns up gain. I queried the file winui7.exe in Google without any result.
Does anyone have an idea what these entries are, where they come from, and how can the return after each start, cold or warm?
