I cannot seem to be able to scan Microsoft edge it says it is being skipped
This occurs if edge, or any program that uses edge's renderer, is running at the time of the clean. Many "Windows Store" apps run using edge, as do many (traditional) Windows applications.
Usually to clean Edge I do it after the computer first starts up, if I wait too long it's impossible to clean. Although the stuff that gets cleaned pretty much immediately comes back which would be those Windows apps Nergal mentioned in the above post.
