Can't open League of Legends, Network and Sharing Center

I've uploaded a file - amsab.zip - to my OneDrive at Noel's OneDrive
Please download and save it.

Right-click on the saved file and select Extract all...
Change the target to C:\ and click on Extract
Close all windows (it would be a good idea to print these instructions!)

Now reboot to the Repair Environment - as soon as the machine restarts, start tapping F8 - this should bring up the Advanced Boot Menu, at the top of which should be the option 'Repair my Computer'
Pick that
You'll have to log in with your username and password.

Pick the option to use a Command Prompt
At the prompt type
DIR C:\amsab
hit the enter key - if you get a 'Not Found' error try
DIR D:\amsab
or
DIR E:\amsab



The drive letter in use when you find the folder will need to be substituted (for<drive>) into the following command...



XCOPY <drive>:\amsab <drive>:\windows\winsxs /y /i /s /v /h



(e.g. XCOPY P:\wfire P:\windows\winsxs /y /i /s /v /h )



run the command (it should take almost no time) and when the prompt returns, type
EXIT
and hit the Enter key to exit Command Prompt - reboot to Normal Mode Windows.

Now run SFC /SCANNOW in an Elevated Command Prompt
then reboot and upload the new CBS.log file to your reply

The SFC scan is now clear :)

Now go to windows Update, and do a manual Check for Updates - install only the oldest found update.
If you get an error message, tell us exactly what it is.
If it installs OK, try installing any further ones (a few at a time).

Ya, windows corrupt files had probably nothing to do with your game. It was still important though to clean the threats as well as fixing your install. Which is now done.

Try using robo uninstaller to completely uninstall it and remove league of legends.

Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

Then install again.

Also see if this helps:

LoL Launcher Fix - League of Legends Community

If all else fails, contact their support.

Glad we were able to get you sorted :)

Good luck!

Also, please read my suggestions so you do not get infected again:

I advise you to install and use the following security programs so you do not get infected again:

-Panda antivirus -You can only have 1 antivirus installed at a time, I recommend using this one and uninstalling what you are using now.

-Malwarebytes
-Superantispyware
-Should I remove it

Run them around once every 2 weeks.

Should I remove it is not a malware scanner. What it does is it looks at all of the installed programs on your PC and gives you a percentage % of how many people uninstall the software. If the percentage % is high, I would remove it as it is most likely not a good program. It also gives a ton of information about what the program does and how it behaves.

I also suggest using a standard user account in windows, and only using an admin account when you need to install software:

User Account - Create

When using a standard account and you make a change or install a program that affects the whole system, UAC will prompt you to continue. Make sure the setting or program you are tying to install is listed, then click yes to continue. If you are just browsing the web and the prompt appears with a program you have not heard of, or do not know what it is, it is much safer to click no then yes. No will block the action, and if you were trying to do something, you can always start it again and choose yes.

UAC makes this easy, see here:

What is user account control (UAC)?

I also suggest choosing always notify for UAC:

What are User Account Control settings?

Those are my recommendations to you, and I Highly suggest you follow them.
