Probably you want to use Windows Server 2008 as your default operating system, but because of the 60 day limit you haven’t installed it yet. This guide will explain how to reset up to 3 times so you have 240 days (4 x 60 days) time to evaluate. Don’t rearm if you don’t need to, because if you do that you waste the evaluation time you had remaining! Microsofts Knowledge Database explains a way to configure it will automatically reset each 60 days, but the Task Sheduler gives an error when you try to import the Task, because the maximum interval between triggers is 31 days, and the .xml file tries to set a delay of 59 days. The information in this guide is the same information as the KB article.
1. First we are going to take a look how many days we have left to evaluate Windows Server 2008. Click Run in the menu Start, then type slmgr.vbs -dli and click OK. Be patient after clicking OK because it will take some time before it will show you a Windows Script Host message window that says how much time you have remain.

2. If the message window previous screen says you have only a few days left do the following to reset the evaluation period back to 60 days. Click Run in the menu Start, then type slmgr.vbs -rearm and click OK. After a couple of seconds it will show you the message window that the command has completed. Restart your system to apply the reset!

3. To verify your evaluation period is reset after reboot click Run in the Start menu, enter slmgr.vbs -dli and click OK. A few moments later it will show you, you have 60 days left again!

What happens if the evaluation period expires? Is it still possible to re-arm the trigger afterwards?
March 11th, 2008 at 0:04
When I run the ’slmgr.vbs -dli’ I get a 59 days remaining time. But because it’s a VOLUME_KMSCLIENT channel, it will attempt to do a automatic activation within 3 days.

If you have access to MSDN - Partner Program - your key works perfectly. Also, the key works with the 2008 Workstation build that is floating around on usenet.

IIRC, it is 30 days for retail SKUs and 60 days for MSDN SKUs.

mr valorisa,i do it in my machine to ur project (http://windows2008.blogdns.com/slides/0.asp) but last (SLUINotify.dll)file dosn’t delate (destination folder acces denied)you need permission to prform this action. how can delate this plz tellme…thanks

Hello,
If you can’t delete one of these files (SLUI, SLLUA or SLUINotify.dll) you can try to move SLUINotify.dll to a place of your choice, for example the Desktop or an other place (but not in c:\windows\system32 or c:\windows). I have had the same problem and have found this solution.
A good advice : make a directory on your hard disk and name it “SLUI_backup” and move the 3 files SLUI, SLLUA and SLUINotify.dll to this directory. Do not delete these files…
Let us know the result.
Thanks.

Does anyone know how to do the automatic rearm so you do not have to do all this manually, I have the code but dont understand how to do it
May 11th, 2008 at 13:32
Hello,
You can use the CLI (command line interface) with “schtasks” to activate a dynamic rearm but don’t forget that at the end you will have to buy the product or try the Sergio Mcfly’s method…

I try this one, but after updating files on micro$oft, i got a note on the right side bottom of the windows Very near in the clock when I restart my computer, not coz it is to fast say:”The copy of this file is not Genuine” please clarify…
Admin: Are you sure you haven’t entered any serial during the installation and haven’t tried any activation crack available on the internet? None of the pc’s i installed it on has this problem.
May 20th, 2008 at 21:45
Hello,
The indication “The copy…is not genuine” is normal but this method (without crack, serial or malware) works if you have followed the differents steps.

The new lik :

and click on “ByPass”

All that does is turn off the Activation nag warning. After 60 days your computer goes into non-compliance mode like any other failed-to-activate computer, which means you fail WGA checks, can’t download from Microsoft Update, etc.
May 29th, 2008 at 11:10
Hello,
At least, have you made a backup of SLLUA.exe, SLUI.exe and SLUINotify.dll like said previously ?
After 60 days, you can again launch a “slmgr.vbs -rearm”. The Windows Update works fine. Today I have did a Windows Update and no problem.
Now after 240 days (60 days + 3 * rearm), I don’t know how W2k8 reacts with Windows Update.
An notification please here to check that this works or not ?
valorisa
May 29th, 2008 at 12:32
Perhaps you are right but with Vista installed there is 1 year, the Mcfly’s method allow the Windows Update. Can you send us a screenshot about your problem please ?
I continue to investigate the problem.
Isn’t there anyone here for a confirmation please ?

Hello,
If the system clock of your machine is out-dated, the Windows Update won’t work.

I did it !
If you follow all the steps since the installation your copy will work for everything. I tested a bunch
Thanks MCFLY.

Hello all, if I was able to follow the McFly slides (awesome)
and delete all of the three files should I see “activate today” instead of “60 day(s) to activate” ?
Is the method simply to delete those files or did I possibly do something out of order or wrong that leaves me with the 60 day left warning.
I am trying this on server 2008 enterprise x64.
Thankyou!
June 1st, 2008 at 5:54
I think I just answered my own question by setting the clock forward a few months and rebooting.
I now see “activate today” and I was offered to change my password.
I also see a product key near the “activate today” I can’t remember if that was there before or not.
Thanks to all those that brought this to light and McFly, you are golden!
June 1st, 2008 at 5:59
btw, you don’t need to type run for most of this other very useful stuff. Just type the name of the service or the command in the search box. If you can’t remember the full name of say, services.msc (is that even it? I forget
) just type service and names start popping up above for you to click on.
June 1st, 2008 at 8:56
I thought I added another comment?
I think I answered my own question, by setting my date a few months forward and restarting I did see “activate today” and I was prompted to create a new password!
thanks
June 1st, 2008 at 12:21
Hello,
It’s for me the best method because it’s a clean method that doesn’t add a malware or other software within the system and the most important : the Windows Update works fine if the date is correct.
Thanks dOGHAIR and Eric for your response and your tests about this method. If you set the date of few months or years forward, you will see the message “active today” because the period of 60 days will be finished.
Don’t delete the 3 files but make a backup if a day they are required by the system.

I found another clean method to delay the activation:
Open regedit, then go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SL and modify the key SkipRearm to 1 and then you will be able to rearm again.You need to modify this registry key every time you want to rearm again.
June 12th, 2008 at 22:47
Hello,
Thanks Sawo. I’ll try this soon. An other good news to rearm infinitely W2K8.

June 13th, 2008 at 15:25
Yes, i tried it on virtual pc 2007 and so far it works flawlessly!
June 13th, 2008 at 18:53
Hello,
I’ve tried your method but it’s doesn’t work if you have applied before the Mcfly’s method. Normal because the SL UI Notification Service is disabled and SLLUA.exe, SLUI.exe and SLUINotify.dll have been moved or deleted.
I think that your method works fine. So, it’s a method or the other but not both.
Thanks for your test.
Valorisa
June 13th, 2008 at 20:55
Yeah it will probably not work if you remove the activation service etc, but it may work if you put back the deleted files and the service.I will test that scenario if i have free time these days.
June 16th, 2008 at 13:33
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SL
those reg keys are all at the above location
change skiprearm to 1
change vlactivationinterval to 240
change vlrenewalinterval to 20160
run slmgr.vbs -rearm
reboot
run slmgr.vbs -dli
result window says Licensed
with no information pertaining to evaluation period at all
is it fully licensed now… maybe since the evaluation details are now gone
June 23rd, 2008 at 12:01
Ive tried these methods.. but now i get the “this windows is not genuine” watermark. Did i do something wrong?
June 25th, 2008 at 17:54
vlactivationinterval sets the retry period for KMS initial activation attempts. At 240 minutes it will retry every 4 hours, probably not what you want. vlrenewalinterval is the required interval to re-contact the KMS server to keep the activation from lapsing. The default is 30 days. At 20160 minutes it gives you 2 weeks, again probably not what you want.
Disabling the SL service simply turns off the nag warnings. After 60 days you still go into non-compliance mode.

The image host for your slide presentation has taken down the images. Perhaps you can just use flickr and make a photostream?
July 23rd, 2008 at 17:12
change skiprearm to 1
just do that and get back 3 times to rearm
