System Restore Using Windows 10 Recovery USB Drive

System Restore is a utility that resets the computer's configuration data (a.k.a the registry) back to the values they were at a prior date and time. If your computer can boot, and you notice your computer acting sluggish or that you are experiencing error messages, the first place to start is to perform a system restore back to a date and time you know the computer was working normally. If The Computer Is Running

1. Right Click The Mouse On The Windows Start Menu Icon.
2. Select Control Panel
3. On the Control Panel Screen, click on Recovery.
4. On the Advanced Tools screen, click Open System Restore.
5. On The System Restore screen, click Next.
6. On the Restore Your Computer To The State.... screen, select a restore point that corresponds as to when you knew the computer was working fine. You can probably just go back to the restore point just before the most recent restore point. Then click Next.
7. On the Confirm Your Restore Point screen, Click Finish. The computer's configuration files will be restored to the state they were in corresponding to the date of the restore point.
8. Reboot the computer. Observe it's operation. If there are still issues, you may have a virus. Run virus protection or boot from a Recovery USB stick and perform repairs offline.

If The Computer Was Booted From A Recovery USB Drive

If the computer does not start normally, and thus was booted from the USB Recovery drive, do the following to run a System Restore.

1. Since the computer was booted from a recovery drive, technically, it knows nothing about the Windows installed on the computer. Thus, when running the utility, it is necessary to tell the utility which drive you want to check for errors. To find out

Enter the command fsutil fsinfo drives and the press Enter.

A list of drives will appear (i.e. C:, D:, E:) Now, it is necessary to inspect each drive to see if it contains the Windows installation. Note IT IS NOT ALWAYS THE C drive!. To do this. repeat the following for each drive.

(1). Enter C: (or any other drive letter) and press Enter.
(2). Enter in Dir and press Enter
(3). Look for a folder named Windows in the list. If it is found, write it down. If not found, repeat steps 1 - 3 for each drive (4). Change Directories back to the offline boot directory (i.e. cd x:\)

2. Now that we have the drive that Windows boots from, we can run the offline system restore

rstrui.exe /offline:e:\Windows and press Enter.

The System Restore utility will start. NOTE. Substitute the drive letter where your windows is installed for the e:\ in the example above.

3. Follow the prompts making sure to select a prior restore point that you are pretty sure is safe.
4. When the restore completes, remove the USB Drive from the PC and reboot.

If the system boots normally, then great, you are done. However, if an error occured during the System Restore process, or there were no restore points because System Protection was not on to begin with, then the backup registry hives will have to be restored manually.
