Activate Office 2021 using CMD

Step 1: Open cmd program with administrator rights.

Step 2:  Get into the Office directory in cmd.

cd /d %ProgramFiles(x86)%\Microsoft Office\Office16

cd /d %ProgramFiles%\Microsoft Office\Office16

Step 3: Install Office 2021 volume license.

for /f %x in ('dir /b ..\root\Licenses16\ProPlus2021VL_KMS*.xrm-ms') do cscript ospp.vbs /inslic:"..\root\Licenses16\%x"

This step is required. You can not install the KMS client product key of Office without a volume license.

Step 4: Activate your Office using the KMS key.

Make sure your device is connected to the internet, then run the following commands.

cscript ospp.vbs /setprt:1688

cscript ospp.vbs /unpkey:6F7TH >nul

cscript ospp.vbs /inpkey:FXYTK-NJJ8C-GB6DW-3DYQT-6F7TH

cscript ospp.vbs /sethst:s8.uk.to

cscript ospp.vbs /act

If you see the error 0xC004F074, it means that your internet connection is unstable or the server is busy. Please make sure your device is online and try the command “act” again until you succeed.
