[WSRV] Check which .NET Framework versions are installed

CMDLET:

Get-ItemProperty -Path “HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full” | Format-List Release



https://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx

1. On the Start menu, choose Run.
2. In the Open box, enter regedit.exe.

   You must have administrative credentials to run regedit.exe.
3. In the Registry Editor, open the following subkey:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

   Note that the path to the Full subkey includes the subkey Net Framework rather than .NET Framework.

   Note
   If the Full subkey is not present, then you do not have the .NET Framework 4.5 or later installed.

   Check for a DWORD value named Release. The existence of the Release DWORD indicates that the .NET Framework 4.5 or newer has been installed on that computer.

1. The value of the Release DWORD indicates which version of the .NET Framework is installed.
   Important

   The following table lists the keys of released versions of the .NET Framework only. It doesn't list the keys of preview or pre-release versions.

[WSRV] Hyper-V VM doesn't start. “‘General access denied error’ (0x80070005)”

1. Note the Virtual Machine ID that is listed in the "‘General access denied error’ (0x80070005)" error message.
   
   For example, consider the following error message:
   
   
   ‘VMName’: IDE/ATAPI Account does not have sufficient privilege to open attachment
   ‘E:\VMs\VMName\Disk0.vhd. Error: ‘General access denied error’ (0x80070005). (Virtual
   Machine ID 5FC5C385-BD98-451F-B3F3-1E50E06EE663)
   
   In this example, the Virtual Machine ID is 5FC5C385-BD98-451F-B3F3-1E50E06EE663.
2. Open an elevated command prompt.
3. To give the Virtual Machine ID (SID) access to the .vhd or .avhd file, type the following command, and then press Enter:

   icacls <Path of .vhd or .avhd file> /grant "NT VIRTUAL MACHINE\<Virtual Machine ID from step 1>":(F)

   For example, to use the Virtual Machine ID that you noted in step 1, type the following command, and then press Enter:

   icacls "E:\VMs\VMName\Disk0.vhd" /grant "NT VIRTUAL MACHINE\5FC5C385-BD98-451F-B3F3-1E50E06EE663":(F)

4. Start the virtual machine.
