The internet is a network so it's not accurate to write that you are not on a network.
Since it is a possible security issue, disable item 1 and don't bother item 2.
As to purpose, the description of item 1 reveals its purpose. The second item is only interesting to those that are diving into performance tests.
Win XP home, sp2
TweakUI / LOGON / ACCESS CONTROL
There are 2 choices...
1. . This is the current setting... (set by windows during win install)
"CONNECT TO REGISTRY REMOTELY", which controls permission to access the HKEY_LOCAL _MACHINE branch of the registry over the network. these permissions are combined with the the permissions on individual keys.
2. . Alternative choice.
"ACCESS PERFORMANCE COUNTERS", which controls permission to access performance counters used by system Monitor and Performance Logs and Alertss. (who/what does the accessing?)
I am only user, only one computer, no networking... Unless I allow individually, I do not want anyone to have network access to my computer under any circumstances.
Will there be any problems/benefits with computer if I change to "ACCESS PERFORMANCE COUNTERS"?
WHAT is purpose of either of the 2 choices? Unless I allow individually, each request, I do NOT want anyone other than me, to have access to anything.
