can i use it? or it will cause my system any error if i clean registry junk?
IMO, the only safe cleaner out there is CCleaner.
Yepp, never had a problem using it
Here is something about their application for Android :

Despite its popularity, ads promoting Clean Master manipulate Android users with deceptive tactics when browsing websites within the app’s advertising framework. Ferenc László Nagy of SophosLabs Hungary has captured some pop-up ads that lead to Clean Master, warning you that your device has been infected with a virus. ... Only if you press “OK” the ad redirects you to the download of the Clean Master app, and does not “remove” the (fake) virus as the ad claims.I can imagine they do the same with the Windows application.
Cleaning = removing things.
When doing so, there is always a change that something goes wrong.
There is no cleanup tool in the world that can do something that you can’t do already manually.
With relevant knowledge you can even do a better job then any cleanup tool does.
You may be right Eddy but, how long will that take ???
Ccleaner does an excellent job, has never given me a problem and the few items it may not touch, really don’t bother me.
After all, we no longer have 8 Meg HD’s. 
I think that the beauty of CCleaner is that it doesn’t seem to go to great depths in its cleaning, both Hard Disk or Registry. Reducing the possibility of doing any harm rather than cleaning.
But when cleaning the registry you should always do a backup of any changes made.
if we found any error after cleaning registry by ccleaner then how we will reset that registry again even we backed up before cleaning it?
because laptop wont start up normally?
If the system didn’t start you’d try running CCleaner in safe mode, or install an earlier image of your system.
Safest move is to NOT clean the registry. Space saved and speed improvement realized by cleaning the registry are
only noticeable when using sophisticated tool. No real life speedups will be noticed.
Speed improvements aren’t the reason you would clean your registry, it’s purely for de-clustering the registry of leftover rubbish which can cause re-install issues with some programs - AV’s etc
You’re talking about targeted cleansing which is totally different than using tools like Ccleaner to clean the registry which can lead to systems not restarting.
I doubt it, CCleaner doesn’t go deep enough and it’s one of the tools I’m comfortable letting my mother run, and her in herself is a liability
You are entitled to your opinion.
Usually I’ll go into the registry after CCleaner has done it’s bit and manually remove everything that it fails to clean, CCleaner barely scrapes the surface.
But cleaning the way you do is nothing for beginners or newbies.

I found some registry problems while scanning with ccleaner.
I didn’t fixed them yet. As it may give some problem to my pc so can I leave them as it is now? Or I have to fix them?
No kidding, I’m not telling people to go into the registry, I’m simply saying that CCleaner doesn’t go deep enough to cause any harm and is safe enough to clean the registry with but you should still use CCleaners option to backup the registry first before doing so.
Without knowing what they are we cant give an answer.
Provided you leave the default settings alone, you are correct with respect to not causing any harm.
No kidding, I'm not telling people to go into the registry
Sorry, I didn’t mean it that way. But as a warning.
;D
