Windows 10 April 2018 Update: Here's what you can expect
The System Restore feature has been a part of Windows for decades. In Windows 10 it's still useful for recovering quickly when a new app or device driver causes instability.
System Restore works by creating snapshots called restore points, which keep backup copies of your system configuration, including registry settings, driver files, and third-party programs. It works best when you restore your system configuration immediately (or at least very soon) after making a change to system settings.
Primarily as a disk-space-saving measure, Windows 10 disables the System Protection feature and deletes existing restore points as part of setup. If you want to use this feature, you must first turn it back on. Here's how.
First, in the search box, type systempropertiesprotection and press Enter. That opens the System Properties dialog box, with the System Protection tab visible.
In the list of drives available for protection, find the system drive (C:) and check its status. If this setting is Off, the System Restore button and the Create button are both grayed out and unavailable.
Click Configure and then click the Turn on system protection option. From this dialog box, you can also adjust settings for disk space usage and delete any existing restore points. Click Apply and then OK to close the dialog box.
Windows saves some restore points automatically (with each cumulative update installed through Windows Update, for example), but it's never a bad idea to take a system configuration snapshot manually before installing a new app or a downloaded driver or low-level system utility.
On the System Protection tab, click Create to manually create a restore point. Be sure to give it a descriptive name (such as "Before installing new printer driver").
If you detect problems after making a system change, first uninstall the app or driver using Settings > Apps > Apps & Features. Then run System Restore (Rstrui.exe) to restore the previous system configuration.
