Luckily, thanks to tools like System File Checker (a tool developed by Windows - you can read more about it on Microsoft's website) you can easily revert the damage made.

Think of Windows as of our civilization. We prospered thanks to the knowledge acquired by our ancestors - we didn't have to reinvent the wheel every time. One way in which Windows stores that knowledge are cache files. When you turn on your computer, the cache files' task is to quickly bring Windows up to speed so that you won't have to wait for Windows to go all over the same processes again and waste your time.

Sometimes, however, cache files can become corrupt. Maybe they were damaged by a program you installed, or as a failure of Windows to replace them with newer cache files. The solution is simple - clearing the system cache files. If you haven't cleaned your computer for some time, this is more likely the case.

In order to clear the system cache, and fix System Restore error 0x800700b7, follow the steps below to the letter:

1. Press Windows button and R to open the Run box;
2. Type regedit in it and click OK;
   
   

   
   
   

3. Navigate to the following destination, by clicking on the folders on the left side of the window:
   
   "HKEY_CURRENT_USER" >Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify
   
   
4. Delete the IconStreams and PastIconsStream keys.
   
   

   

   
   
   
5. Open the Task Manager (CTRL+ALT+ESC) and under Processes, select Explorer.exe and click on the End Process/Restart button to end/restart it.
   
   

   

System restores need peace and quiet to return your PC to a state when it worked like a charm. A program being installed, or another process running on your computer is a reason good enough for the system restore error 0x800700b7.

Before you begin restoring Windows to its last known good configuration, make sure to check the following:

• No programs are being installed;
• No programs are running in the background (that entails Facebook, or Google, too - make sure to close them);
• No antivirus scans are taking place.
• No system or program updates are taking place;
  
  

Once you verify that none of the above takes place, try restoring Windows again.

If something went wrong during the system restore process and Windows won't load, an option you have is booting the computer to the last known configuration, by following the steps below:

1. Turn off the computer, either by pressing (and holding) the power button or by unplugging it from the power cord;
2. Turn on the computer and press the F8 button repeatedly.
   * If that didn't work, press and hold the power button, and the computer should redirect you to the Advanced Boot Options screen;
3. Use the keyboard's arrow buttons to navigate to Boot to the last known configuration and press Enter.
   
   

   

This will restart your computer. Once your computer powers back on, you have another chance to make things right, this time investigating what went wrong with the first System Restore attempt, before running the restore again.

No one likes viruses in real life. They make us feel bad, and in rare cases, their outcome can be very unpleasant. Such is the case with computer viruses, also known as malware. If you visit many pages on a daily bases, the probability of a virus infecting your computer is much higher. Maybe the virus is the root cause that led you think about restoring your computer in the first place, causing the System Restore error 0x800700b7 to occur.

If a virus is indeed the root cause of this issue, all you need to do is to remove the virus, by installing and running an antivirus software, and once the virus has been neutralized, your computer should be fine.

Check out the viruses / spywares / malware guide to learn how to scan for and remove viruses and protect your computer against them.

Although the antiviruses are meant to protect us against threats, sometimes they can make our head hurt. Maybe the antivirus software is the culprit, as it believes that the System Restore point is malicious, and won't let you run it. Usually, this is not the case, however, it's best to be careful sometimes. Disable the antivirus software, by right-clicking on its icon in the notification area (bottom-right corner of the screen, near the date and time) first, and then run System Restore again, to restore your computer to its last known good configuration.

Note: Antivirus software are disabled in different ways. Some are easier to disable than others. Check out the antivirus help guide, and you will learn how to disable it.

The best way to defeat enemies is while they are asleep. Maybe it's the Safe Mode that can help you fix the System Restore error 0x800700b7.

1. Press the Windows and R keys on your keyboard;
2. Once the Run box opens, type msconfig and press Enter.
3. Click on the Boot tab and tick the checkbox next to the Safe Boot option;
   
   

   

4. Click on OK to save the change;
5. Restart your computer;
6. Open System Restore, and try restoring your computer again.
   
   

Note: Repeat steps 1 through 5, once the System Restore process has been successful.

The fact that System Restore files have been damaged shouldn't be neglected. You being unable to make Windows boot proves that point. Luckily, if you keep the Windows Installation DVD or USB, you have an intact and brand new System Restore utility at your disposal.

Follow the steps below, if you couldn't make Windows boot, and to run System Restore:

1. Put your USB or Windows DVD and restart your computer;
2. Keep pressing F12 until the select a bootable device screen appears;
3. Select the Windows DVD or USB from there and wait for Windows files to load;
4. Press Shift and F10 to access command prompt;
5. Type rstrui in the Command Prompt and press Enter;
6. Start the restoring process and wait for it to finish.

Maybe System Restore brought down your entire Windows OS, and even though the situation may be very bad, there is still light at the end of the tunnel, if you or someone you know keep the Windows Installation DVD or USB. Aside from containing the installation files, the Windows DVD or USB keeps a wide variety of diagnostic and repair tools in its hat. All you need to do is to run them, and forget about System Restore errors.

Follow the steps below, if you couldn't make Windows boot, and to run System Restore:

1. Put your USB or Windows DVD and restart your computer;
2. Keep pressing F12 until the select a bootable device screen appears;
3. Select the Windows DVD or USB from there and wait for Windows files to load;
4. Press Shift and F10 to access command prompt;
5. Type diskpart and press Enter;
6. Type list volume in the Command Prompt and press Enter;
7. In the list, find in which partition (volume) Windows is installed. Usually it's the smallest one in size, and it's labeled C.
   
   

   

   
   
8. Type exit and press Enter;
9. Type the following command and press Enter:
   
   sfc /SCANNOW /OFFBOOTDIR=<partition/volume>:\ /OFFWINDIR=<partition/volume>:\windows
   
   If Windows was installed in C, then, the command would look like this:
   
   sfc /SCANNOW /OFFBOOTDIR=C:\ /OFFWINDIR=C:\windows
   
   

   

10. Restart your computer;
11. Start the restoring process and wait for it to finish.

Just like Hansel and Gretel left stones, System restore leaves system restore points, generated deliberately because one of them may get corrupt. Maybe your latest restore point was corrupt. This would explain why System Restore keeps failing. If this is the case, you can resolve this error by restoring Windows to an earlier restoring point, by following the steps below:

1. Open System Restore;
2. Click on Next;
3. Select one of the older restore points and click on Finish.
4. Keep waiting until the system restore process is complete.
