Hello!

Here I have some tips that I found useful to put on my blog while working with Windows 10

 

Cannot run sysprep - "Sysprep was not able to validate your Windows installation"

 

 

 

Set Windows Photo Viewer as default

Really hate the new photo default viewer of Windows 10, and hate the most the fact that we have to do some fiddleing to get the old viewer back, arrghh. At present, when I try to view *.jpeg files on my Windows 10 I get this error messages:

 

Create an import a .reg file with this data:

After you have imported the *.reg file, you can right-click the affected picure and choose Open with > browse to Windows Photo Viewer and choose to open it as default

 

Change registered owner of the system

Fire up the register and visit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion and if you don't have it created these two entries (String Value)

  • RegisteredOwner
  • RegisteredOrganization

 

Install .NET Framework 3.5 in Windows 10 (error code 0x800F081F)

It may happens that, after the installation/upgrade of Windows 10, you got an application (app as it is called nowadays in Microsoft language) that needs .NET Framework. Right, the best way to install this is by going to appwiz.cpl >  Turn Windows Features on and off > and tick the NET 3.5, but eventually you'd be given this error message:

To fix this nasty error, I've done as follows:

  1. Search Duck Duck for "Windows 10 iso" and download the Windows 10 installation media from here: https://www.microsoft.com/en-gb/software-download/windows10
  2. Choose "Create installation media for another PC". choose the *.iso format and save it at the root of the C:\ drive
  3. Once the *.iso download is completed, right-click to it and mount it, note the drive letter being assigned (on my example the letter E:\)
  4. Finally, open cmd in privilege mode and run this command:
dism /online /enable-feature /featurename:netfx3 /all /source:E:\sources\sxs /limitaccess

 

Windows Server 2012 R2 - Windows Update fails

If you can't run Windows Update on your windows box, execute this command under admin rights:

DISM.exe /Online /Cleanup-image /Restorehealth
