If you have a new Certificate with the current Private Key

Import Certificate into Certificate Store 

certutil –repairstore my <serial number>

If you have a new private Key then you made a new CSR?
You should see a pending Request in "Certificate Enrollment Request" of your Cert Store

#Install the certificate with certutil
certreq -accept -machine C:\Install\test.cer
