Windows 7: Deleted Temporary Files in Disc Cleanup - Was This Wrong?

Deleted Temporary Files in Disc Cleanup - Was This Wrong?

Earlier I used the Windows disc cleanup to clean my C Drive. I have just viewed a video on Youtube about optimising PCs, and he said not to check the box to remove temporary files as it causes problems. As I have removed them, what are the likely consequences?

Also, I had a look at restore points in case I wanted to go back so that the temp files could be reinstated. Strangely, there aren't any dates for restore points. Does this mean that by cleaning up the temp files, I have also removed restore points? Should I set up a restore point now?

Disk Cleanup is safe to use. I use Disk Cleanup several times a week.
Disk Cleanup does not remove Restore Points.
Disk Cleanup has never caused any problems for me.
Disk Cleanup is a Windows 7 built in tool. Windows does not like or want to hurt Windows.

I would suggest you set your Restore Point volume to 5% and create a Restore Point.

It is rare that removing temp files creates a problem. Some apps (like CCleaner) will (by default) only delete "old" temp files. But again, you should not see any problems after removing temp files. Any app that keeps important files in a temp folder is a poorly written app.

It won't hurt to manually create a system restore point.

I'll let others speak to the impact (if any) of disk cleanup on system restore points.
edit: I see that Layback Bear has already addressed that issue.

Thanks for your quick replies. So, by checking the box and cleaning out my 'Temporary Files', I haven't removed anything important, Windows or otherwise? On the cleanup facility, are there recommended boxes to check and uncheck, or is it safe to check all?

Can you tell me how to set a restore point volume, please. Also, why are there no restore points? There were some a few days ago when I had to use one for something else.

As for C Drive, I have used 87GB from a total of 140GB.

By default Disk Cleanup doesn't delete important temp files (new files created within 7 days)

See here to change that behavior if required:

To the best of my knowledge, Windows 7 built in Disk Cleanup does not delete temp files that Windows 7 needs. Windows 7 tries it's best to protect itself.

CCleaner when set to default will not delete temps until they are 24 hours old.

Hi Woodbine,
Disk clean can clear restore points, its part of the secondary option, Clean up System files.
You can select the size of the restore folder from here, see screenshot
Volumn shadow copy needs to be active as well,
check via Control panel >> Admin Tools >> services

Depending on which browser you use, there are in-built options to clear data at certain points.

Yes their are methods to clean Restore Points if one cares to.
I have never had Disk Cleanup do such a thing.

Hi
LBB allways used it, no problems at all.

Do the same on my W10 TP's, getting rid of the "old" files, after enabling it

I say that it is safe to put a check by every box in the Disk Cleanup tool; even if you run the tool as admin (which offers more to check). If there was an important temp file for some 3rd party app, then that app should let you know that a file can not be found. You can always install that app again

I have no idea what happened to your restore points.

I am unable to get the Disk Cleanup tool to remove system restore points - even ones that are from last year.
