Windows automatically deletes older restore points to make room for new ones so that the total number of restore points doesn't exceed the space allocated for them. (By default, Windows allocated 3% to 5% of your hard drive space for restore points, up to a maximum of 10 GB.) If you want to increase the number of restore points, you need to allocate more space for them.
To increase the number of restore points, use Windows' built-in search capabilities to look for "restore point," without the quote marks. In the search results you should see a result for "create a restore point." Select this result and Windows displays the System Protection tab of the System Properties dialog box. (No, you aren't creating a restore point, but this is the fastest way to display the System Protection dialog box across all applicable versions of Windows.) (See Figure 1.)

Select the drive you want to hold more restore points and click the Configure button. Windows displays the System Protection dialog box for the drive you selected. (See Figure 2.)

Use the slider control near the bottom of the window to indicate the maximum space you want allocated for restore points, then OK your way out. You will now have more space on that drive to hold additional restore points.
