my Login wouldn't give an option to log on as Administrator (Ctl+Alt+Del, usual break to administrator),
I don't know how it is with XP Pro; on XP HE you can only reach the real "Administrator" by booting in safeMode (F8-Boot) for the 1st time.
Afterwards, it should be available via normal boot or logoff/login
In Win2000 (since SP2/SP4 ?) there are subtle, but mean differences between adminUser and the one-and-only, REAL "Administrator" concerning what they can or can't do.
Maybe also in XP ?
I was able, after a reboot, to log on as administrator, simply by Ctrl+Alt+Del (twice) this breaks out to clasic login and enabled me to login as administrator.
what changes exactly did you do/customize ? maybe avast recognized those as identical to "HIGH" security, and thus kept the slider there..
It took some doing to make custom stick even as administrator, in effect I had to virtually sellect most of the advanced options. The thing that I beleive made it stick was in Scanner Advance to scan all files. From here I was able to reboot and login as User and the settings had stuck.
I did try to adjust some of the settings in customise and it reverted to High again and I had to repeat the above exercise again, weird when I have administrator privileges.
Hopefully that's the end of it but I now knw how to sort it if it happens again (administrator).
Thanks to all for your assistance and time.
