Windows 10: How does 'slmgr rearm' command work?

Hi,

I saw many people on YouTube showing tutorials to reset windows trial by using the command 'slmgr rearm'? I wanna know how this works?

:)

 

Windows Not Genuine - Won't Let Me Run SLMGR -REARM

My friend recently got the familiar (and annoying) black screen and the "windows is not genuine" warning.

I tried everything - scanning for viruses, I removed the KB971033 update, etc. I opened a command line prompt as administrator and tried to run SLMGR-REARM. It failed with a 0x800700005 (access
denied) error.

I have tried all of the online fixes.

Is there Microsoft Fixit for this? Any other suggestions?

Thanks.

How to Rearm and Extend Free Usage (Activation Grace Period) of Windows 7 to 120 Days

‘Rearm’ trick on Windows 7 is done using the similar commands and steps with Windows Vista. Follow these steps to reset and extend activation grace period from 30 days to 120 days in Windows 7:

Type any of the following commands into the command prompt, and then hit Enter:

Code: sysprep /generalize slmgr.vbs –rearm rundll32 slc.dll,SLReArmWindows slmgr /rearm[/quote] As rearm only works for 3 times, make sure the command is only been run when the 30 days countdown of evaluation period is almost expired.

its legal, and its allowed. there is no pirated keys, no cracks, nothing breaks the EULA.

Discussion of cracks and such is still a nono, but the rearm trick IS allowed to be discussed here.
