I only have old system restore points

ded9 has told you how to delete the April Restore Points.
 
"how can I see the size in disk space of april restore points"
See Option1 item 5 here
http://www.sevenforums.com/tutorials/700-system-restore.html
Highlight the Disk name for which you wish to have this info and click Configure to see amount of disk space you have allocated to System Restore.  I suggest 2-5% of the size of the hard drive.

"how can I have more current restore points"
It seems you have had System Restore turned off for some months, but now that you have one new one, it must be turned back on.
Again in the window you get by clicking Configure (as above) make sure you do not have a check next to "Turn off System Protection".  I suggest you check "Restore System Settings and Previous Versions of files".

You can also create individual Restore Points by highlighting the Disk name for which you wish to create and Restore Point and then  clicking "Create" on the screen shown in item 5 in the link posted above.

I do not want the april restore points and I think these restore points are taking up alot of disk space.

are your ideas to stop system restore deleting all the restore points and restart system restore

"are your ideas to stop system restore deleting all the restore points and restart system restore"

With respect, please re-read what I have posted.

ded9 told you how to delete the exisiting Restore Points.

My post told you
1)  how to allocate sufficient space to allow Restore Points to be stored
2)  how to determine that System Restore is turned on (so it can create Restore Points).
3)  how to create individual Restore Points.

System Restore, when turned on, will automatically create Restore points from time to time.
When the Disk Space is no longer sufficient to accommodate a new Restore Point, the oldest Restore Point will be deleted to make room for the new.

Click the More Options tab, under System Restore and Shadow Copies, click Clean up.

In the Disk Cleanup dialog box, click Delete.

Click Delete Files, and then click OK.

To delete the April Restore Points try:
Highlight the Disk name of the disk you want to work on.
Then in the window you get by clicking Configure (as above), under Disk Space Usage, click Delete.
Click Continue, and then click OK.
Reboot.
The April Restore Points should be gone.  Make sure you have allocated some Disk Space for Restore Points for the disk concerned (the one you highlighted).  You should now accumulate Restore Points normally.

"same screenshot"
I do not see that you have posted a screenshot.

Yes, http://www.sevenforums.com/tutorials/700-system-restore.html is a tutorial.  I posted it only so you could see the image in Option 1, item 5 to help you understand the suggestions I was making.

You are working on System Restore.  As already mentioned
"See Option1 item 5 here

I did step1,2
and restarted computer
but still have the same april restore points listed




and step3 shows there are no restore points from april

rgb192--Did you go back and reopen System Restore to see if it now shows only the most current Restore Point?

Yes

And/or look in the Configure window (Image for Step 7 in Option One in http://www.sevenforums.com/tutorials/336-system-protection-restore-points-delete.html ) to see what it shows for Current Usage?  If it show zero or close to zero, I would suspect you really do not have those April Restore Points.  And this would be very close to answering your original question as to how much disk space they were using.

4.7 gig

Other thoughts.
Are you running as Admin?
Have you rebooted after the various deletion procedures?

Yes, Yes

After being provided with all the different tools, I noticed I can turn off system restore and turn back on.  
Thank you for making the process easier.

rgb192--Glad to have helped.
I regret I did not mention earlier that turning System Restore off will also delete existing Restore Points.  Glad you saw that.
