How to uninstall any version of Java

I wanted to uninstall Java from all the machines and install the latest one. There were sometimes multiple versions of Java which had to be removed. Some machines had both 32 bit and 64 bit Java versions. Here is the easiest batch script to uninstall any version of Java on the machine.
There were scripts available but they did not delete 64 bit versions of Java and some very old versions of Java. Hence I modified those scripts to meet my need.

set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive )
set mycmd=reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall /s /f *java* for /f " usebackq delims={} tokens=2" %%i IN (`%mycmd%`) do ( msiexec /uninstall {%%i} /passive )

VBScript to change the proxy settings if disconnected from VPN

When connected to VPN, user's IE proxy settings get changed and is forced by VPN.
Often the users might get disconnected from VPN while working from home and this does not revert back the proxy settings to the original one.
I have written a VBScript to change the proxy settings of the users. This script can be made a shortcut and then used.

'Script Created by Piyush Nasa
'Script to change Proxy settings for user if disconnected from VPN

Option Explicit
Dim valUserIn
Dim objShell, RegLocate, RegLocate1
Set objShell = WScript.CreateObject("WScript.Shell")
On Error Resume Next
valUserIn = MsgBox("If you have been disconnected from VPN and want to reset your proxy, click Yes and restart Internet Explorer",4,"Proxy Reset")
If valUserIn=vbYes Then
RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer"
objShell.RegWrite RegLocate,"","REG_SZ"
RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable"
objShell.RegWrite RegLocate,"0","REG_DWORD"

'Enable AutoDetect in the proxy by calling this sub

MsgBox "Proxy is reset to AutoDetect"

'I do not want any proxy so I have disabled this, but if you want to set a proxy then you can use this.

'RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer"
'objShell.RegWrite RegLocate,"xxxx.xxx.com:80","REG_SZ"
'RegLocate = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable"
'objShell.RegWrite RegLocate,"1","REG_DWORD"
MsgBox "Your Proxy is not changed."
End If

 SUB IEautomaticallydetect

 DIM sKey,sValue,binaryVal
 Dim oReg

Packaging Skype with Auto Update disabled

EDITED: I have edited this post on 30-Aug-2013 after some users comments that the given solution is not working. I have studied in depth the skype update process and created this solution for all. Please check below (Edited Section) for more information.

Recently while packaging Skype for enterprise version, I could not disable the Auto Updates and finally found a way to get rid of it.

You can get the latest version of Skype setup in MSI format from the following URL: http://download.skype.com/msi/SkypeSetup.msi or

There is no registry, file which can disable the Auto Update functionality of Skype. I searched in lots of forums and all said that it automatically prompts for update. So finally I decided to look in the MSI and find why and how it is doing it.

What I found was that Skype has an Updater.exe in the installation folder and it also creates a Skype Update service which points to this exe.
I just removed this service and updater.exe file from the skype msi package and it worked.
No need to do anything else. Just do this small part and you are done with removing the Auto Update in Skype.

I have been asked and told by a lot of users that this is not working so I am adding a further solution which will definitely work without a doubt. I have mass deployed this and it has worked fine. For all the users who were getting the pop ups, this has fixed it.

You need to create a dummy SetupSkype.exe file and a Skypefix.vbs as below and add it to your INSTALLDIR (C:\Program Files\Skype\Phone\) of the package.

dim filesys, oShell
Set filesys = CreateObject("Scripting.FileSystemObject")
Set oShell = CreateObject("WScript.Shell")

des1 = oShell.ExpandEnvironmentStrings ("%Temp%")
sup = oShell.ExpandEnvironmentStrings ("%ProgramFiles%")
windir = oShell.ExpandEnvironmentStrings ("%Windir%")

destfile1= des1 & "\SkypeSetup.exe"
sourcefile1= sup & "\Skype\Phone\SkypeSetup.exe"

'Copy files

If filesys.FileExists(sourcefile1) Then

 a= filesys.CopyFile (sourcefile1, destfile1,True)

End If

oShell.Run windir & "\System32\Icacls.exe " & destfile1 & " /deny Everyone:D"


After this you need to create an Active Setup registry key which will run this vbs file for every user who logs off and logs in. After this there will be no upgrade issue.

This script works on the fact that SkypeSetup.exe gets downloaded from internet to %temp% folder of user and when it is downloaded, it starts prompting up for upgrade. I have created this file before hand in %temp% folder or replace the already existing one with this dummy file and then put a deny restriction to all the users on this file. So now a file cannot be downloaded to %temp% folder because there is already a file which cannot be deleted/replaced. Hence no more upgrade prompts.
I have created this solution by deeper understanding of Skype setup and upgrade.

Hope this tip will be helpful to you and let me know if it still does not work.

How to clear App-V Cache

This has become my favorite site today because one of the issue which I was facing in App-V while testing was because the App-V cache was not getting cleared.
I used one of the method used here and it worked for me.
I want to share this link with all and want to bookmark it for myself for future reference.


In Summary, these are a few good options to start with:

First, get a list of all AppV applications:
sftmime query obj:app /short
Remove all applications from the cache:
sftmime.exe remove obj:app /global /complete
Remove a specific application from the cache:
sftmime.exe remove app:”applicationName” /complete

Hope your issues are solved with this as well.

App-V with Java/JRE/JDK

It is very critical to understand how to handle installation of Java related applications in App-V environment.
While some are of the view that the application should be installed along with Java in the same bubble while some say that the Java version installed on the base machine can be used.

Here is how you can do both of these in a proper way:

1) Java installed locally on the machine: If Java is locally installed on the machine and you capture the App-V application, then you will see a hard coded entry in the registry. This basically points the App-V application to look for Java in this local machine location. If you upgrade your Java version from say 1.6.21 to 1.6.24, then you do not need to worry, however, if you do a major upgrade from 1.6.21 to 1.7.xx then you need to upgrade your App-V Application as well. You need to maintain the software library for all these applications and then upgrade them as part of Java Upgrade in the organization.

2) Java is installed as local copy inside App-V bubble: Java can also be installed as a local copy with your App-V application. There can be various reasons for doing this:
 a) Application is compatible only with a certain version of Java
 b) Application uses a higher version which is not locally installed.
 c) If Software manager do not want to upgrade the application every time Java gets updated.

In these cases a private copy of Java can be captured with App-V. However, there is a procedure for achieving this.
These steps will be helpful in doing this:

Detection Method for MSU in Applications for SCCM 2012

In SCCM 2012 Applications you can have a detection method set for MSU with KB numbers.

You can use the Powershell or VBScript to do this. Here is an example of both.

Powershell Script:

get-hotfix | Where-Object {$_.HotFixID -match "KB981603"}


'Returns info if Windows 'KB981603'  in installed
' ----------------------------------------------------------'
Option Explicit

Dim objWMIService, strComputer
strComputer = "."

'Run the query
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" _
    & strComputer & "\root\cimv2")
Dim QFEs
Set QFEs = objWMIService.ExecQuery ("Select * from win32_QuickFixEngineering where HotFixID like 'KB981603'")
For Each QFE in QFEs
    Wscript.echo "Update KB981603 was installed by " & QFE.InstalledBy & " on " & QFE.InstalledOn

Permissions to registry using setacl

Recently I was trying giving permission to one of the registry hives with Subinacl, but it was not working despite all efforts and checking all the syntax and a lot of troubeshooting.

Then I came across another permission granting utility known as SetACL. It worked like a charm. So you can try using this utility is Subinacl fails.

You can download SetACL from http://helgeklein.com/download/

Here is an example to run SetACL to give registry permissions.

"SetACL.exe" -on "hkcr\Interface" -ot reg -actn setowner -ownr "n:Administrators"
"SetACL.exe" -on "hkcr\Interface" -ot reg -actn ace -ace "n:Users;p:full"

  • Object name (-on): This is the path to the object SetACL should operate on (file/directory/registry key/network share/service/printer).
  • Object type (-ot): What kind of object does the object name refer to: file or directory (file), registry key (reg), service (srv), printer (prn), network share (shr)?
  • Action (-actn): What should SetACL do with the object specified?

A lot more details and description can be found at this awesome site: http://helgeklein.com/setacl/documentation/command-line-version-setacl-exe/

Install MSP file with MSI

While handling with MSP of applications, sometimes a question comes in mind that can an MSP be installed along with MSI?
The answer is yes, but with a few conditions involved.
The conditions are explained later in the post with some description.

First I will give you the command line to install MSP along with MSI:

msiexec /i {Path to MSI}\Installer.MSI PATCH={Path to MSP}\Patch.MSP /qb

If there is a transform as well to add you can include it in the command line as well.

msiexec /i {Path to MSI}\Installer.MSI TRANSFORMS={Path to Transform}\Transform.MST PATCH={Path to MSP}\Patch.MSP /qb

The only thing which you have to take care in the command line is that you will have to give a complete path to MSP.
Relative paths do not work in this case.

This will apply the patch as in the updated files will be installed from the patch rather than from the MSI.

This process is greatly useful when there are a lot of patches to be applied to an MSI.

There might be cases that the MSI is already deployed on your client machines and you need to patch it with this new patch which has come now. You can deploy the MSP over the MSI and then it is suggested to change the initial MSI package to include the MSP.

If you have multiple MSP for an MSI then the way you implement it actually depends on the way the MSP are created for the MSI. There are two kinds of MSP:
1) Incremental
2) Add-on

The above ones are my terms and not Microsoft's and I am using them just for explaination purpose.

In Incremental MSP, say version 1.2 contains all the content for version 1.1 and so can be installed directly on top of MSI which is version 1.0. Similarly version 1.3 will install directly on top of MSI version 1.0. So you can skip the previous MSP version and directly install the latest version on top of your MSI.

In Add-on MSP, the MSP has only additional data from the previous version of MSI or MSP. For example, say version 1.2 has a few files added but it does not contain the files/registries which were added or modified in version 1.1 of MSP. So in this case you will have to install both MSPs, version 1.1 and 1.2 one after the other on top of MSI version 1.0
You can use command line like this:
msiexec /i {Path to MSI}\Package_1.0.MSI PATCH={Path to MSP}\Patch_1.1.MSP; {Path to MSP}\Patch_1.2.MSP /qb

The order of MSP mentioned here is important as it will install in that particular order only.

I hope this article is helpful to you in organizing and maintaining your Operational work with Application Packaging.
