You were working on finding how to speed up your Internet connection that was very fast in startup. You clicked on control panel, all control panel items, performance information then you believe you selected advanced tools. A window came up with little boxes marked.
Their was a box that said enable all or disable all. Well you hit disable all and said to apply. You figured that you could come back and hit enable all if nothing worked. Your computer is not responding to many commands.
It will not even connect to the Internet now. You are running Windows 7 64 bit home premium, it is an upgrade from Vista. You have tried finding a window under advance tools but cannot find a window with all of those little boxes to check or to re-enable.
I recommend you reboot your computer first to see if you can get into that same advanced window. If your still not able to access specific menu to reverse your changes, then you can try to perform a Windows 7 system restore. Basically, you pick a date before you made these changes for Windows 7 to be restored to.
Open system restore by clicking your "Start" button. In a search box, type "System Restore", and then, in the list of results, click System Restore.? If you're prompted for an administrator password or confirmation, type that password or provide confirmation.
You can try booting your computer into Windows safe mode to try to reverse your changes. Reboot your computer and press your F8 key after your system powers on. An advanced options window will open.
Choose "Safe mode" in some menu options. Try to change your settings back. Also, you can boot your computer into safe mode last known good configuration.
Follow previous instructions to get into advanced options menu. This time choose "Last known good configuration" from a menu.
