SkipRearm is a genuine technique to extend your Windows 8 activation period.
Microsoft supply the registry value, and publish TechNet articles explaining
how it works.
Firstly, note the word 'Skip', this just postpones the need for activation.
Secondly, please realize that this is not a backdoor way of legitimising some dodgy
Windows 8 product key.
Thirdly, it helps to understand why Microsoft has kindly provided this
registry setting. The biggest beneficiaries of SkipRearm are companies who use sysprep to
create hundreds of legitimate copies of Windows 8. It may be weeks
between creating the 'Master' copy of Windows 8, and installing the cloned
software. Employing SkipRearm, means that you can extend the grace
period for activation.
Now here is the tricky bit, I would like to explain the relationship between the registry
setting: SkipRearm, and the command line: slmgr -rearm.
Remember that slmgr is a built-in vbscript; while SkipRearm is a registry
value.
Here is the technique: prior to cloning the Windows 8 master
machine, set SkipRearm to 1, the licensing state is not change.
When you are happy with this master copy of Windows 8, use Sysprep /
generalize to set SkipRearm to 0. This resets the 30-day activation
timer to day 0.
At anytime run slmgr -dlv or slmgr -dli to display the current licensing
and activation information, or better still, run slmgr -xpr to reveal the
present expiry date.
The key point is that you get 3 chances to run slmgr -rearm. Let us check the
logic of SkipRearm = 0, meaning count one of the 3 lives, and SkipRearm = 1, meaning don't count one of those lives. In conclusion, changing the registry key to SkipRearm = 1, means don't use up one of
my three lives.
Guy Recommends: SolarWinds Engineer's Toolset v10
This
Engineer's Toolset v10 provides a comprehensive console of 50 utilities
for troubleshooting computer problems. Guy says it helps me
monitor what's occurring on the network, and each tool teaches me more about how the
underlying system operates.
There are so many good gadgets; it's like having free rein of a
sweetshop. Thankfully the utilities are displayed logically: monitoring,
network discovery, diagnostic, and Cisco tools. Try the SolarWinds Engineer's Toolset now!
As a preliminary experiment, check the Windows 8 activation expiry date with the command: slmgr -xpr
Launch Regedit.
Navigate to this path: *HKLM\Software\Microsoft\Windows
NT\CurrentVersion\SoftwareProtectionPlatform
Double-click SkipRearm and change the value to 1.
Now remember to run the 30 day extension command: slmgr -rearm
Restart the machine. After it reboots, run slmgr -xpr and check the expiry date.
Check the registry
setting SkipRearm, slmgr resets the value to zero.
Note 1: This registry hack does not make any sense on a
machine which has already been activated!
Note 2: Regedit has a 'Favorites' tab, I always click
and 'Add to Favorites', this saves a great deal of time in trying re-find
obscure registry settings such as SkipRearm
Note 3: *HKLM means HKey_Local_Machine

Guy Recommends: SolarWinds Network Topology Mapper (NTM)
NTM will produce a neat diagram of your network topology. But that's
just the start;
Network Topology Mapper can
create an inventory of the hardware and software
of your machines and network devices. Other neat features include dynamic
update for when you add new devices to your network. I also love the ability to export
the diagrams
to Microsoft Visio.
Finally, Guy bets that if you test drive the Network Topology
Mapper then you will
find a device on your network that you had forgotten about, or someone else
installed without you realizing!
Research indicates that
you can only make this SkipRearm registry hack 7 times to delay Windows
8 activation.
Additionally, you can use slmgr.vbs -rearm three times, making 10 delays in all.
The knowledge that SkipRearm was designed to assist corporations with sysprep;
this helps us to understand why this registry
hack will work with these three versions of Windows 8: Enterprise,
Professional and Ultimate. However, I have heard rumours that it will also work with upgrade version of
Windows 8 Home Premium.
By saying, cheats never prosper, I am not
seeking to take the moral high ground; it's more
that I want to pass on advice learned from the hard school of
knocks. Here are the results from previous attempts to beat Microsoft's licensing agreement, none had a happy ending.
NT 3.51: Install an evaluation copy, then apply a service pack to remove the 120 day restriction. (Urban Myth)
NT Workstation: Change two registry keys and turn a Workstation into NT Server. (Would you risk a company server on a registry hack, just to save $300?)
Windows Server 2000: Attempt the setupreg.hiv hack to bypass activation. (Plain did not work)
The Windows
8 Activation hack SkipRearm fails after 7 attempts. Also, it
probably does not work on Home editions.

Summary of Windows 8 SkipRearm
The SkipRearm registry setting is designed to help large companies, who
roll-out Windows with sysprep, or deploy other cloning software. While
its true that you could use this as cumbersome method of extending the life
of any computer before activation times-out, SkipRearm is not a backdoor
method of making a dodgy product key legitimate.
