It is not difficult to search for the download link of Windows Enterprise or Windows Enterprise LTSC on the internet. If you download it from the Microsoft Evaluation Center page, you will get a copy of the Evaluation version. You probably don’t know that you can not use a product key to activate Windows Evaluation. You need to convert it to the Production version first before purchasing a product key. To do this, just follow the instructions below.
Step 1: Open the skus folder in the C drive.
Use hotkey [Windows + E] to open File Explorer then enter in the address bar: C:\Windows\System32\spp\tokens\skus
If you installed Windows on another drive, just replace C with the drive letter of that one.
Step 2: Get the latest SKUs for your Windows here, then extract the archive file. Just copy the folder Enterprise (for Enterprise), EnterpriseN (for Enterprise N) or EnterpriseS (for LTSC) to the skus folder in step 1.
Click Yes if prompted.
Step 3: Open cmd app with administrator privileges then run all the commands below.
cscript.exe %windir%\system32\slmgr.vbs /rilc
cscript.exe %windir%\system32\slmgr.vbs /upk >nul 2>&1
cscript.exe %windir%\system32\slmgr.vbs /ckms >nul 2>&1
cscript.exe %windir%\system32\slmgr.vbs /cpky >nul 2>&1
cscript.exe %windir%\system32\slmgr.vbs /ipk PRODUCTKEY
sc config LicenseManager start= auto & net start LicenseManager
sc config wuauserv start= auto & net start wuauserv
Replace PRODUCTKEY with corresponding key below.
Enterprise: NPPR9-FWDCX-D2C8J-H872K-2YT43
Enterprise LTSC: M7XTQ-FN8P6-TTKYV-9D4CC-J462D
Done! You can double-check the system info now.
