UAC in Windows Vista

I have found a fix for the adminsitrator access without turning off UAC.

Open the Run Command and type secpol.msc
This will open the Local Security Policy.

Browse through the Local Policy to the Security Policy. Click on the Security Policy folder. In the window to the right locate:

User Account Control: Behavior of the Elevation prompt for administrator’s in Admin Approval Mode.

Change it to: Elevate without Prompting.

Then reboot. This has gotten rid of a lot of problems for me.

Compound TCP – Improve throughput

Compound TCP – Improve throughput
Add-On Congestion Control Provider

The traditional slow-start and congestion avoidance algorithms in TCP help avoid network congestion by gradually increasing the TCP window at the beginning of transfers until the TCP Receive Window boundary is reached, or packet loss occurs. For broadband internet connections that combine high TCP Window with higher latency (high BDP), these algorithms do not increase the TCP windows fast enough to fully utilize the bandwidth of the connection.

Compound TCP (CTCP) is a newer method, available in Vista and Server 2008 (there is also a hotfix available for XP/2003). CTCP increases the TCP send window more aggressively for broadband connections (with large RWIN and BDP). CTCP attempts to maximize throughput by monitoring delay variations and packet loss. It also ensures that its behavior does not impact other TCP connections negatively.

By default, Vista and Windows 7 have CTCP turned off, it is only on by default under Server 2008. Turning this option on can significantly increase throughput.

To enable CTCP, in elevated command prompt type:

netsh int tcp set global congestionprovider=ctcp

To disable CTCP:

netsh int tcp set global congestionprovider=none

Possible options are:  ctcp, none, default (restores the system default value).
Recommended setting: ctcp

It is better to use this newer generation CTCP congestion control algorithm for most broadband connections, we highly recommend it being turned on.
