A lot of the answers here are referencing the almighty hosts file, and indeed, that is your best bet. Here's an automated solution provided by some smart guys over at StackOverflow that utilizes no third party software. You can bundle this up into a batch file and run as a Windows task that unblocks at certain times and completely forget about it.
This approach has several upsides:
- Free (no downloads required)
- Easy to schedule times with Windows Task Scheduler
- OS level blocking of websites
- Enough of a hassle to undo that you will probably stop yourself before you go through with it.
Here's the code for the batch files:
code for blockfacebook.bat
echo 0.0.0.0 www.facebook.com >> c:\windows\system32\drivers\etc\hosts
code for unblockfacebook.bat
setlocal enableextensions disabledelayedexpansion
for /f "tokens=* delims=0123456789" %%a in (
'findstr /n /i /v /c:"facebook" "%file%" ^& type nul ^> "%file%"'
) do (
Just copy paste these into Notepad and save with the .bat extension and double click on them to test.
Scheduling a task:
from Microsoft's website:
You must be logged on as an administrator to perform these steps. If
you aren't logged on as an administrator, you can only change settings
that apply to your user account.
If you use a specific program on a regular basis, you can use the Task
Scheduler wizard to create a task that opens the program for you
automatically according to the schedule you choose. For example, if
you use a financial program on a certain day each month, you can
schedule a task that opens the program automatically to avoid the risk
of forgetting to open it yourself.
Open Task Scheduler by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security,
clicking Administrative Tools, and then double-clicking Task
