Hi Marsha,
- Are you using AVG antivirus program?
- Have you connected the computer to any domain network before?
If your system is not in a network, you have no need for this service and you can disable it. If you are in a network, but do not habitually browse the network for file shares, you can also disable this service. Disabling it does not stop you from accessing file shares on other computers, it just prevents you from using my network places to browse to them.
This service maintains links to NTFS files that are moved between disks or computers.
Note: It is not recommended to disable the service. However if you still want to disable, you may follow the steps.
a. Click on Start > type "services.msc" in the search field and press enter.
b. In the "Services" window, look for the following entry:
c. Distributed Link Tracking Client
d. Double click and set the "Startup type" as "Disabled"
e. Click on OK to validate.
