Quickie: Real location for virtualized files and registry keys when using UAC

October 22nd, 2014 No comments

This is just a note. When you have UAC (User Access Control) enabled and if application wants to write data into %ProgramFiles% all writes are redirected into %localappdata%\virtualstore\. If application writes into registry HKLM\Software it is redirected to HKCU\Software\Classes\VirtualStore.

That’s all folks,

 

Quickie: How to delete registry using reg file

June 6th, 2014 No comments

I always used .reg files to import registry keys and values. I started to think if it’s possible to delete registry key or value using .reg file.

To create key and value you can use following .reg file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\test]
“test_value”=dword:00000010

 

To delete only value “test_value” you can run following .reg file (minus sign after the equal sign):

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\test]
“test_value”=

 

To delete whole key you can run following .reg file (minus sign in front of key name):

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\test]

 

That’s all for now,

 

APP-V exclusion in registries

October 8th, 2012 No comments

Last week I was playing with application virtualization. I do have experiences with VMWare Thinapp applications. I already did couple of those virtualized applications. When I was forced to use App-V to create virtualized application I needed to make one application and I needed make this application to write registries into real registries and not to virtual ones. I thought it would be same as in VMWare Thinapp. That means I would expect to set some “isolation” mode on registry branch.

Problem is that you can define only two modes in App-V for registries:

  • Merge with Local Key – This will merge real registries with virtual ones. Change will be written into virtual registries.
  • Override Local Key – This will show only virtual registries to application and changes will be written into virtual registries.

In VMWare Thinapp there are isolation modes (for file system structures and also for registries) defined as following:

  • Full – Real are not shown. Any modification goes into virtual. New elements go into virtual.
  • Merged – Real are shown. Modification of virtual goes to virtual. Modification of real goes to real. New elements go to real.
  • WriteCopy – Real are shown. Modification of virtual goes to virtual. Modification of real goes to virtual. New elements go to virtual.
