Windows 7 RTM x64 – Missing driver of CD / DVD drive during installation

Yesterday I downloaded Windows 7 x64 from MSDN and burned the image on a rewritable disk.
Soon after the welcome screen of the setup it displayed me that the driver of the CD / DVD drive is missing.
First I was wondering how it is possible that I boot from DVD and it can read the DVD but then it displays a message that the driver is missing. It is a little bit strange.

So I tried it once again with the same result.

If solved this problem by installing Window 7 from my USB-Drive.
In order to do so you have to do the following steps:

  1. Open the command line (CMD) width administrator rights
  2. type Diskpart and press enter
  3. type List Disk and press enter
  4. type Select Disk ZZ (Replace ZZ with the number which represents your USB Drive) and press enter
  5. type clean and press enter
  6. type create partition primary and press enter
  7. type active and press enter
  8. type format fs=fat32 quick and press enter
  9. type assign and press enter
  10. Just copy all files of your disk to your usb drive
  11. Restart and boot from USB

Now you should be able to install it without problems

Firefox – Memory Leak – How to solve the problem?

Perhaps you already have the problem that the firefox needs to much RAM.
Sometimes it can grow up to 800 MB and more. The reason for this problem could be one of the addins or even the system which caches internet sites in order to load them faster.
And because of that it could happen that firefox slows down the whole system.

But with this workaround you can solve the problem

  1. Enter about:config in your address bar
  2. Perform a right click in the textwindow and select New >> Boolean
  3. Enter config.trim_on_minimize in the textbox
  4. In the following dialog select true
  5. Now you should see a new entry with the name config.trim_on_minimize
  6. Restart Firefox

When you minimize Firefox you can see in the Taskmanager how it trims the memory
