same here... getting the 'evaluation copy' screen bug... i reported it and i was told it had something to do with the 'beta' and 'developer' insider program; not sure i totally understand how that creates the screen bug--it's still there in the latest 'beta' insider update... not sure if this has anything to do with it but i noticed a significant slow down in programs loading and internet browsing... i had to completely shut down my desktop, restart it, then restart it again; this is after using ccleaner to clean up the registry and browsing files... the computer seems to be okay now but i hope in the next update the memory integrity and 'evaluation copy' issues are addressed... i may just leave the insider program and just let my computer update normally via the regular updates...
