Annoying: Ask Toolbar install with Java

How many times have you install or simply updated your Java, only to be asked once again to install third part software such as the ask toolbar?

How many time have end users in your company also done this only to have the tool bar eat away at resources on their workstations or conflict with in house applications?

Well did you know, that in the Java Control Panel  there is a setting located under miscellaneous which allows you to suppress the sponsored offers when installing or updating new versing of Java.

How cool, now go and make that change.

While your at it, you could push out a registry change to all of your Active Directory to ensure this is in place:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft]
“SPONSORS”=”DISABLE”

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft]
“SPONSORS”=”DISABLE”

Set SharePoint Content Database in Read-Only Mode

This weekend I am working on a SharePoint 2010 to 2013 upgrade.

One of the steps; the beginning steps I will do is set the databases I am upgrading into read only mode to prevent users or automated process from upgrading the database during the upgrade window.

Now I could have taken the system offline for this; but that would be simple and inconvenient for anyone looking for information.  And in IT its all about the Information now isn’t it. You can find my steps below.

SharePoint Application Server

  • I first logged into my central administration of my SharePoint Server (SharePoint 2010).
  • Under Application Management, Select Manage content databases
  • Chose your web application  and select the database
  • You will notice that there isn’t a location to set this database into read only mode; however you do see that its status indicates its not in read only mode.
  • Keep this page open, as we will reload it later.

SharePoing SQL Database Server

  • Log into your Microsoft SQL Database Server (Or use SSMS).
  • Launch SQL Server Management Studio (SSMS)
  • Connect to the SQL Database Server instance
  • Select the database in question
  • Right click and select Properties
  • Under properties select Options
  • Scroll down to the area that reads “State”
  • You will see Database Read-Only
  • Change the value from False to True, then click OK
  • You will see a notification that it will momentary kick active users.
  • Click OK to continue.

Now you can revisit the SharePoint Application Server and reload the page and you will now notice that the status has changed and is in read only mode.

Congrats, if you followed these steps you did it right.

Delete Google Play App History

I have been thinking about this for a while, how I could delete those apps that I have downloaded but never intend to use “EVER” again. And if you one day decided to restore all of your apps, those come along with it. No Bueno, my friends.

I have looked up and down the Google Play Store via my PC and couldn’t find a way to do this. So I turned my focus to my phone. Yes; I found it… So say goodbye to that insanely long apps list by doing the following:

  1. Launch the Play Store App
  2. Tap the menu button and choose “My Apps”
  3. At the “My Apps” menu choose “ALL” – Here you will see a list of all the apps you ever installed; wow I have downloaded a lot of apps in my past.

For the apps that are no installed you can simply click the (X) in the upper right corner to remove the app. You can select multiple apps by holding down one of the apps (phone will vibrate) and you can continue to select multiple apps until you’re ready to delete them all in one swift click.

I hope this has helped you.

How to upgrade ESXi 5.0 to ESXi 5.1

For some of you that may not know ESXi 5.1 has been released. If you are like me running it for free at home or in the office, you may have asked yourself. How can I update my existing ESXi 5.0 installation without needing to use a CD / USB. Well my friends, it’s good you stopped by.

First thing you need to down and go on and log into your VMware account and download the ESXi 5.1 Offline Bundle (a file named VMware-ESXi-5.1.0-799733-depot.zip). While your are there you should download all other ESXi 5.1 related downloads; You’ll only need them later anyhow.

Next you need up upload the bundle to a data-store that your host has access to. This can be done via the vSphere Client or any other SCP client such as WinSCP or Filezilla FTP Client. Once uploaded to a data store you can can SSH into your host and run the following commands to update your system:

or

When done you will find yourself back at the command interface and all you need to do is type ‘reboot‘ and wait about 5 min’s for the system to go down.

Please note that you should have already powered down any and all virtual guest systems before updating to minimize on the time it takes to reboot

Additional Notes: (if you are just patching 5.0 for the use with Win8/Server12

Consider this guidance, which is based on testing Windows 8 / Windows Server 2012 up to build 8224:
  • Windows 8 Developer Preview / Windows Server 2012 Release Candidate does not boot on ESXi 5.0. To resolve this issue, you must install patch ESXi500-201112001 (Patch 02):
    1. Download and install ESXi500-201112001 (Patch 02). For more information, see VMware ESXi 5.0, Patch Release ESXi500-201112001 (2007680).
    2. Create a new virtual machine configured for either Windows 7 or Windows 2008 R2.
    3. Enable 3D graphics or do not install VMware’s WDDM video driver.
    4. Install Windows 8 / Windows Server 2012 from Media.
    5. Install VMware Tools.Note: VMware does not recommend installing VMware’s WDDM video driver. Use the default VESA driver.
  • If you experience a black screen after installing VMware’s WDDM video driver in a virtual machine with Windows 8 / Windows Server 2012, enable 3D graphics or reinstall the operating system and VMware Tools without VMware’s WDDM video driver.
  • VMware does not currently recommend using USB xHCI with Windows 8 / Windows Server 2012. To work around this issue, remove the USB xHCI controller or use the USB EHCI+UHCI controller.Note: Any changes to the virtual hardware must be preceded by a full shutdown on the command line (shutdown /s /t 0 /full). Otherwise, the Windows 8 / Windows Server 2012 hibernate-shutdown may not fully detect hardware changes and you may experience a blue diagnostic screen or triple fault at boot.
  • The vmxnet3 virtual NIC does not work in a Windows 8 / Windows Server 2012 virtual machine with ESXi 5.0. To work around this issue, use e1000e or e1000 NICs.
