VMGuest.iso for older Windows OSes in Win10/2016

Posted by essjae on March 2, 2017

If you’re playing around with older OSes in the latest versions of Hyper-V, you’re missing one thing, the Integration Components (IC).

With Win10/Server2016 they no longer include this ISO as the current “supported” OSes all get their IC viaWindows Update.

You can get the IC from Hyper-V 2012/2012R2 Server, a free download, here:

https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2012-r2 (you’ll need to either find a way to extract it or install Hyper-V Server in a VM to get the vmguest.iso)

Or, if you’ve got a Windows 8/8.1/2012/2012R2 VM/system available with Hyper-V installed you’ll find it in the C:\windows\system32\ folder.

I’ve got a copy from Hyper-V 2012 R2 here: https://1drv.ms/u/s!AnbqFQxI6C6pidtRrLfIRLDSHKeYmw

No guarantees how long MS will allow it will stay up here, though it’s freely distributed with Hyper-V Server.

No More Ransom Compiles List of Free Anti-ransomware Tools

Posted by essjae on December 16, 2016

“The No More Ransom project, a coalition of law enforcement and security companies, has expanded with 30 new members and added 32 new decryption tools for various ransomware variants,” Computerworld reports.

First launched earlier this year, the No More Ransom project is headed by Europol’s European Cybercrime Centre, the National Tech Crime Unit of the Netherlands’ police force, Kaspersky Labs, and Intel Security. As of today, No More Ransom has announced that Bitdefender, Check Point, Emsisoft, and Trend Micro have joined as associate members. “Other companies, computer emergency response teams, information sharing and analysis centers, and industry associations have joined the project as supporting partners,” Computerworld says. “The organizations have contributed an additional 32 new decryption tools to the existing eight, which have so far been used by over 6,000 victims to successfully recover their ransomware-encrypted files.”

Easy (lazy) way to get your serial number for your Dell, or other OEM system?

Posted by essjae on November 15, 2016

Need your serial number?  Laptop’s docked, or workstation not easily accessible?

Here’s an easy way to get your vendor serial number:

  1. Start a command prompt, click start, type “cmd”, hit enter
  2. type “wmic bios get serialnumber”

This will return your Dell, Lenovo, etc serial number.

Note: If you have a custom or home built system, you’re not likely to get an serial number, you’ll probably see something like  “system serial number” or “to be filled in by o.e.m”
