Since installing NIS 2010 on my PC & Laptop, both XP-PRO(SP3), I have the following problems on both, there may be more.
1-I cannot use System Restore successfully, even if I re-instate it from Device Manager.
2-I cannot use MSCONFIG.
3-It seems I can use REGEDIT successfully.
Error on using MSCONFIG:

An Access Denied error was returned while attempting to change a service. You may need to logon using Administrator Account to make specified changes.
