Hi Prashant,

Thank you for responding.

I suggest you to check if the system date and time is correct and disable the proxy if enabled and check if it helps.

Step 1: Check if proxy connection is enabled. If yes, then disable the proxy connection and check the status.

Follow the steps to disable proxy:

• Open Internet Explorer.
• Click Tools and then click
  Internet Options.
• Click on the Connections tab.
• Click on the LAN Settings
  button.
• Then uncheck the option Use a proxy server for your LAN.
• Click Apply.

Step 2: I suggest you to check if the system Date, time and Time zone
is set correct.

Follow the steps to set the date and time:

• Press Windows key from the keyboard.
• Type Date and Time in the search bar.
• Click Change date and time button.
• Click Apply and Ok to save the date and time.

Note: Click on the Time Zone tab to check the Time Zone.

Hope it helps. Reply to the post with an updated status of this issue for further assistance.

 

Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.
