Hello, While it's quite easy to reactivate windows 10 after reinstal with an internet connection, sometimes an offline pc, without internet, should be reactivated after a reinstallation and then, it's difficult. Some suggested to backup the digital license and restore it after. I've found several topics on this but it was never updated. Here we had : https://forums.mydigitallife.net/th...-activation-in-windows-10.70929/#post-1269347 Other websites recommend to backup also other files located here : %SystemRoot%\System32\spp\store\2.0\data.dat %SystemRoot%\System32\spp\store\2.0\tokens.dat %SystemRoot%\System32\spp\store\2.0\cache\cache.dat Others also mention another tokens.dat file located in appdata. I know the official and easy answer is to say it's not possible, anyway it seems that it's achievable. Please, is there any way to know what are the files to backup and restore to preserve locally this digital license, on the same hardware? I know that doing a full backup of my system and restore the backup would preserve the backup, but the reality is that I have to do a fresh install and reactivation on a local account- without connection to internet. Thank you very very much!
The digital license is bound to the hardware it's established on and saved on MSFT servers, as long as the mainboard/lan is not changed no need to back it up at all (and when it changed the backup won't work anyway, then just get yourself a new digital license).
thank you, but it does not answer my question. I know about MS servers. I may have to install the same fresh version of windows 10 from scratch after formating the drive on the same hardware windows 10 was already activated. The challenge is to have Win 10 activated again without connecting to internet, as explained in my question.
It's what I said. With internet connection, easy. without = nightmare. in the past it was possible to use slui 4 but not anymore.
Within the Setup Media > Copy > "\sources\gatherosstate.exe" to your Desktop then Run the EXE > This will create a "GenuineTicket.xml" file on your Desktop To restore the Activation on a Clean Install on the same PC - copy that file into "\ProgramData\Microsoft\Windows\ClipSVC\GenuineTicket" - then restart PC... I usually Prep and Apply the Install.wim to the PC (so I integrate that Ticket File into the wim, and thus present upon first boot of PC - to activate.. )
Considering HWID is an activation method that needs to contact the msft servers to work, offline won't never work, use KMS or KMS38. And it still needs to confirm with msft servers.
I usually do not allow an internet connection at first - but you may be right - things change and memory slips with age.
The activation throughout a digital license of Microsoft will need a working Internet connection, NO way around that! Even if using a KMS activation, an Internet, or at least a LAN wired connection is needed for that activation process because the machine needs to be connected to the KMS-Server. That applies as well if the used KMS Server is located on the same Network, be wired or by WiFi. AFAIK, while using a legal single Product Key, sometimes an Internet connection is needed to keep the Activation alive if the used machine is even just sometimes/shortly connected to the Internet! Only, if you keep the computer strictly of the Internet, the activation maybe will be alive for a longer time.
I think that backing up C:\ProgramData\Microsoft\Windows\ClipSVC\tokens.dat should be enough on w10, but surely backing up also the files from spp you mentioned doesn't hurt
