Windows Optimizer scans out not all of them can be deleted.

It can be deleted, and it is a temporary file that is installed, run, or upgraded.

The system junk scanned by Optimizer can be deleted without worrying; But the registration information is processed for the first time to backup, to prevent the registry file from being deleted, after the first backup, there is no need to back up in the future, you can delete it directly like junk files, I use the optimization master, it feels good.

If it is a system file, it is better not to delete it. Not all the junk files that the optimizer says are really useless. The deletion is too simple, and the system is often not as good as it was before.

Of course, others can be deleted. It is best not to forcibly delete system files.

For example, when you are engaged in a mechanical club, you often generate some backup files in bak format. If you use Optimizer, these must be deleted.

Sometimes it's really not worth it.

I remembered, I used Windows Optimizer to delete the computer, and it can't be used, so you should use it carefully.

I recommend that you do not delete it, because some software may be restored to the original settings, and some software relies on temp (temporary files), so deleting the temporary files will cause the software to restore the original settings.

You can delete it, but please back it up first. In particular, Optimizer reminds you of the files that need to be backed up.

Not necessarily, no matter how good it is, it can't be deleted entirely.

You can't delete them all, it is recommended to use other software to delete junk files.

Theoretically, yes, but it's best to back up before!

I've deleted it all after backing it up, and I haven't had any problems with it so far.

No problem.

If you want to delete all of your home use, I'll do it.

Such third-party optimization tools have the risk of mistakenly deleting useful registry information, and should be done with caution, as it is common for over-optimization to cause the system to eventually hang down and have to reinstall the system

Domestic ones are usually unreliable.

Be sure to clean it up.

We recommend you ccleaner

1、The optimization master scans out a file with a duplicate file name2、The duplicate file name does not mean that the content of the file is the same,You also need to open the file to see if the content is the same,Use the md5 tool to check whether the md5 code of the duplicate file is the same。

3. I see that your scan results have some files that seem to be more important, and it is best to check them clearly before deleting them.

4. If your machine has been used by others, and you are concerned about things in other fields, which has no meaning to you, just click to delete!

It is completely possible to delete since it is a duplicate file.

To be on the safe side: follow the path given above to see if there are duplicate files, and if so, delete the ones you don't want.

Yes, yes, but I feel that the optimizer is not very thorough in cleaning up the garbage, I just changed to a super rabbit to try, and it feels good.

Yes, as long as it is the Optimizer default.

Yes, don't worry about deleting it, it's okay, you don't need to back it up.
