Printer dialog freezes after setting Properties


Printer dialog freezes after setting Properties of (any) printer.



  • DELL Optiplex 9020
  • HP LaserJet 400 M401d (connected with USB)


  • Windows 7 64-bit
  • UAC notify
  • HP PCL 6 driver for Windows 7 64-bit
  • HP printer firmware 20160224

Steps tried before solution

  • carry out sfc /scannnow
  • carry out chkdsk
  • tried updating to lastest firmware and drivers
  • tried different setting in printer properties such as spooling, bidirectional support, rendering, etc.
  • change user role
    • When the user role is User, the printer dialog box freezes.
    • If the user role is Admininstrator, the printer dialog box does not freeze.
    • If the user role is Power Users, the printer dialog box does not freeze.


Set the user role to Power Users.


  • This will not solve all the freeze cases as there were other causes
  • Setting the user role to Power Users may not be feasible in certain cases.

Install Pentaho 4.5 CE as service on Windows 7 x64

After so many searches, trials and errors, I have successfully installed the Pentaho 4.5 as service on my Windows 7 64 bit. The following content describes how did I do it.

  • Install and configure service
  • Q&A

Using many version of firefox

How to use different version of firefox on the same windows machine.

Mozilla team is actively releasing the Firefox recently. It is a good thing and welcomed by many Firefox lovers. Just a thing, not every addon is compatible with the newly released Firefox.

  • install the firefoxes to different folder
  • create separate profile for each firefox
  • change shortcuts to run with separate profile

Quick opening of programs using Keyboard only

Describe how did I achieve to open any program with three key presses.

It is cumbersome to

  • move the cursor to the corner of the screen

  • click the ‘Programs’
  • click the Program folder you like to open
  • click the shortcut to open the program
  • worst, sometimes mouse slipped and menu disappeared and have to start it all over again.

So I tried program launchers based on menu and still the same problem. And my system resource is taken by that program. (I like my computer running light)
