Several people who installed the Technical Preview of Microsoft Office 2010 noticed after 30 days activation will not succeed. This is related to the fact the activation servers of Office 2010 not yet are published via DNS, simply explained to the fact they don’t exist yet. How you can re-activate for another 30 days? I give you a brief procedure how to do it :
First you have to stop the service : Office Software Protection
Then run x:\Windows\System32\OSPPRUN.exe (x can be your C: or other driveletter you have installed windows on)
You will have a prompt.
Enter these command followed by an enter like shown below, go to next step
>Initialize (enter)
>Open (enter)
>GetInstalledSkuIds (enter)
    0. 128a057a-7e95-4063-b296-c54c5f3d3f3a (deze is het ID van Office 2010)
    1. 26adec89-edf3-4adc-a3fc-c865f1a9f71f
OK.
> GetInstalledAppIds 128a057a-7e95-4063-b296-c54c5f3d3f3a (enter)
    0. 59a52881-a989-479d-af46-f275c6370663
OK.
(You will get something that looks like this)
> GetLicensingStatus 59a52881-a989-479d-af46-f275c6370663 128a057a-7e95-4063-b296-c54c5f3d3f3a (enter)
SkuId            = 128a057a-7e95-4063-b296-c54c5f3d3f3a
eStatus          = SL_LICENSING_STATUS_IN_GRACE_PERIOD
dwGraceTime      = 1D 23:37
dwTotalGraceDays = 30 days
hrReason         = 4004F00C
qwExpiration     = 2010/10/31
OK.
(What you are now going to do is set AppID and SkuID for Office 2010 to enable again 30 days before activation. That gives you another 30 days to test. Mostly the IDs are the same, if not please copy and use yours

You can enter the command below to check out how many days you have left (See dwGraceTime):

You are able to use it again for 30 days. Have a lot of fun with testing Microsoft Office 2010…
