Windows 10: Help please can't log in

I think I messed up. So I don't have access to the screen where you put your password. Its just a blue screen and I can't click or write anything. I don't know what I did when I tried to changed the background color for an image, I think I delete something or downloaded a program that messed everything up. Anyway, the thing is that I can't log in my computer and I don't know what to do. Please, help?

Windows 10 failed attempts to use "Backup and Restore (Windows 7)" function

Repeated backup failures. Running Windows 10, and when the “Backup and Restore (Windows 7) program is run front the Control Panel, I get the messages:



“Check your backup. The last backup did not complete successfully”.



“Windows Backup failed to get an exclusive lock on the EFI system partition (ESP). This may happen if another application is using files on the ESP.”



“Please retry the operation.”



Each time I retry, I get the same result and messages.

Windows 10 came installed on my Dell Inspiron 15 (500 Series) laptop. I have successfully used the same Backup and Restore (Windows 7) program to “Create a system image”, as well as to “Create a system repair disc”.

Please provide me with some insight and suggested actions.

 

Running windows 10 and lost browser connectivity after installing the 2013 Microsoft Office Suite

running windows 10 preinstalled on a new Dell lap top had no problem with windows browser, no problem installing Chrome, no problem downloading and activating 2013 Microsoft Office programs. BUT lost all browser connectivity after installing the 2013 Microsoft
Office Suite. Internet connectivity confirmed along with DNS, pings, etc.

Should I uninstall the 2013 Microsoft Office Suite?

 

Isn't there some feature where you can use an image as a password? Yah, there is a "Picture Password" option, did you use that?

You might have to log in via Safe Mode to get into your Administrator account, hopefully you can change it from there.

Also, Is your Mouse working when you are at the "Lockscreen"? - If not, Try unplugging the mouse and plugging it back in. I was having trouble with my mouse not being activated after booting up, I would have to unplug it and plug it back in, but I let Windows Update download "Mouse and Keyboard center" (originally Intellimouse) and now it works each time I boot.
