- This activation method does not store any files on the system.
- This activation method works offline.
- Unlike HWID and Online KMS activation option, KMS38 does not match with any official activation method.
- Make sure the following things have been accounted for, before applying KMS38 Activation:
- Before the activation, if any KMS activator is installed, then make sure to uninstall it completely.
- After KMS38 activation has been achieved, if you want to use the 180 Days KMS Activator for MS Office, then you must make sure that it (the 180 Days KMS Activator for MS Office) is compatible with Windows KMS38 activation. FYI, the following activators are compatible and can activate Office without disrupting the Windows KMS38 activation.

- Any KMS Activator which is not compatible with KMS38 may overwrite the KMS38 activation for Windows with its own 180 days activation, thereby destroying the KMS38 activation for Windows. To prevent this accidental overwriting, you can select the KMS38 protection option.
- In a genuine [KMS](https://docs.microsoft.com/en-us/previous-versions/tn-archive/ee939272(v=technet.10)?redirectedfrom=MSDN#kms-overview) activation environment, activation lasts a maximum of up to 180 days. This is done using a valid license and server setup.
- However, in the Windows major upgrade process, the system uses `gatherosstate.exe` to carry over the remaining KMS activation period. It does it by creating a ticket that can be used offline.
- The trick is that we can fool the `gatherosstate.exe` about the remaining KMS activation period and manually put the desired period maximum up to 19 January 2038 03:14:07 UTC.
It's related to the [Y2K38 problem](https://en.wikipedia.org/wiki/Year_2038_problem) as this date (19 January 2038 03:14:07 UTC) is the maximum date we can give to `gatherosstate.exe` without it looping back to the year 1970.
**A:** Not directly. They could only update Clipup to allow for a maximum activation period of 180 days. Not much besides that can be done on their part. The tickets are not sent to Microsoft at all, so they can't block them or take action directly.
- ServerRdsh edition does not [officially](https://docs.microsoft.com/en-us/azure/virtual-desktop/windows-10-multisession-faq#can-i-run-windows-10-enterprise-multi-session-on-premises) support activation on non-azure systems.
- By default, KMS38 Activation is vulnerable to unintended replacement by a 180-Day KMS Activator.
- If you are going to use [KMS_VL_ALL]((https://github.com/abbodi1406/KMS_VL_ALL_AIO)) by abbodi1406 or [MAS](https://massgrave.dev) (Online KMS option) for **Office activation**, then you don't need to enable this protection.
- However, with a few tricks, you can ensure that no alternative KMS Activator can replace KMS38 Activation by accident or even on purpose. below is the explanation for how to do/undo that.
- In the KMS activation method, Windows first checks the KMS IP registered as a specific KMS, and if that is not defined then it checks the Global KMS IP. Another fact is that if Localhost (IP range 127.0.0.0/8) is defined as KMS IP in Windows 8 and later OS then Windows will not accept it as a valid KMS IP. This script simply utilizes the above facts to protect the KMS38 activation from being overwritten by any alternative 'normal' 180-Day KMS Activation and at the same time that KMS activator can be used for Office activation.
**Further**, in the case of Windows Server Core editions, the system doesn't have `clipup.exe` file. So to activate it, MAS separate files version contains the below file. (It's not included in MAS AIO)
