1) Create a Restore Point using System Restore
2) Create a Repair disc by going to Start...All Programs...Maintenance...Create a System Repair Disc
3) Test the System Repair disc to make sure that you can get to the System Restore entry when you boot from the disk (you may also want to try actually using System Restore to make sure that it works)
4) Download this free program (Autoruns for Windows
) and use it to disable any instances of LVUSBS64.sys
that are starting (or any other Logitech Camera entries) (DO NOT DELETE - only disabled by removing the checkmark in the left hand column)
5) Check in Device Manager (to include showing hidden devices from the View menu item) and ensure that any instances of LVUSBS64.sys
(or any other Logitech Camera entries) are "Uninstalled" (DO NOT DISABLE THESE).
6) Check in the Services applet (services.msc) to be sure any instances of LVUSBS64.sys
or any other Logitech Camera entries are disabled.
7) Go to C:\Windows\System32\drivers and rename the LVUSBS64.sys
driver to LVUSBS64.BAD
In the event that the system doesn't boot:
1) Boot from the System Repair disc and use the Command Prompt option to rename LVUSBS64.BAD
2) Boot from the System Repair disc and use the System Restore option to restore the system to a point before the changes were made.
