Can I use Registry Cleaner? As comments by most users, better not to try it as it may ruin your registry records and files which I do not know. I have just installed Wise Care 365 and pend for any better advice or solution before use.
Do not go for Registry Cleaner.

At the best first try to repair Windows. It should solve most of the issues. Remember to backup your data before repairing windows. Let me know how it goes.
