Step 1. Install new Windows / Office, you can download versions at this link:
Here you need to remember which version and type of Windows / Office you have downloaded (eg Windows 10 version 20H2 Build 19042.630 or Windows 10 LTSC 2019 …), Everyone can do it on their own during the installation process, so I ignore it.
Step 2. Download tool MSAct Plus to check the key and self-activate
You go to the link below select MSAct Plus v1.0.8b3 to download. You need to choose the correct Key with the version of Windows or Office that you have installed.
If the key is able to activate Online, it will automatically activate and report successful activation. (However you should also click on the icon “i” at the end of box 9 to display step 2 and take step 3 to backup). If the key is already online but can still be activated by phone it will appear as shown above with step 2. If the key is blocked, it will indicate the product key has been blocked.
Step 3. (CID) (Step 3)
After completing step 2, we get the ID (Step 2), then proceed to ask for help to get the CID (Step 3) or follow the steps by yourself.

The next important step is to SAVE KEYS FOR USE WHEN YOU HAVE to REPAIR

*** For retailers, after saving the key, press “set key” one more time ….
*** Copy more folder “store” (C: \ Windows \ System32 \ spp) save too ………
D / REACTIVATE:
After for some reason to reinstall
*** Copy and paste the saved folder “store” to the old location. . .



For Office you also perform the same steps. With note
MSAct Plus v1.0.6 (Office 2019 version 1.0.8b3)
MSAct Plus v1.0.8b3 (this version must turn off antivirus first)
(With win 7, you must install netfMp3 4.)
Similarly you can use / – MSAct ++ v2.0.7 to activate
Use:
1. Select the product to activate;
2. Enter the key.
3. Click “Start”
If the key is able to activate Online, it will automatically activate and report successful activation.
If the key has expired online but can still be activated by phone, it will show step 2. (you can select and copy to have to call for step 3)
If the key is blocked, it will indicate the product key has been blocked and no step 2
