Disable UAC on Windows 2012

Wednesday, December 3rd, 2014

I had a need to disable User Account Control on a server 2012 installation.

I had set UAC to “Never notify” but still ran into issues. I learned that UAC is not really disabled with server 2012.

I should note this goes against Microsoft’s best practices but sometimes you need to do that to get things done when a customer won’t give you time to research a better way.

You need to use Regedit and follow this steps.

  1. From a CMD or poweredit; type Regedit then hit enter
  2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system
  3. Double click on EnableLUA
  4. Change the Value data to a 0
  5. Click OK, then reboot the server

After that the error went away.

Normally, I would list the error but I had lost the message(this blog entry was on my todo).

Can’t install .net 3.5 on Windows 8 or 2012

Friday, October 31st, 2014

As Microsoft tries to make things easier; they sometimes cause problems with internal security policies. Like many companies, Windows Update has a few controls on it.

A few Windows 8 installations ran into a problem when they needed .Net 3.5. The update policies blocked the download of needed files for the Windows Features wizard to install it.

Luckily; there is a support note; that explains another method to install.

All that is needed is the DVD or an ISO of the operating system. I used an ISO. A nice new feature is the ability for a virtual drive. Simply copy the ISO, double-click it and and you have the ISO mounted.

After that start an admin level CMD and use the DISM command to install .Net 3.5.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:<Virtual drive letter>:\sources\sxs

It will run for a couple minutes and it didn’t require a reboot.
