GAC Uninstall: Access denied

I am sure you have seen this before and as frustrated as me.

After going through several google searches,this process works

1) When you launch Windows Explorer, there is no easy way to "Run as Administrator"
2) Since Explorer does not have Admin rights, you get "Access denied messge"

To fix

1) Launch Task Manager, and Kill Windows Explorer
2) In Task Manager, go to File-> New Task (Run...), Type explorer and check "Create this task with administrator privileges"




3) Once the explorer launches, you will be able to uninstall from GAC

GPG error:public key is not available

I have a NAS, and when i try to run apt-get update, I got a series of warning messages  like below

W: GPG error: http://ftp.us.debian.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY AED4B06F473041FA NO_PUBKEY 64481591B98321F9

This link gave me the solution. You copy your keys, and run the following command


sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys AED4B06F473041FA

You can either run it for each key, or separate each key by space

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys  AED4B06F473041FA 64481591B98321F9
