可以看到升級後產生的「$Windows.~BT」、「$Windows.~WS」、「Windows.old」這 3 個資料夾，由於在升級過程中會下載 Windows 10 的安裝檔案並將舊系統備份起來，因此佔用的空間十分大，如果你的 C 槽是 SSD 的話很可能就快滿了，因此趕緊刪除它們吧！

Upgrading or downgrading SAU licenses

Upgrading and downgrading to a SAU licensed feature set uses the same commands and similar steps.

Upgrading an SAU license

To upgrade a license on a device that supports SAU licenses, perform the following steps. The examples in these steps show how to upgrade from a 2X10G license to a 4X10GR license on an Ruckus ICX 7150.

In order to perform the following task, you must place a purchase order with Ruckus order management as needed. A unit number and the purchased license name is required.

1. (Optional) Enter the show license installed command to check the licenses already installed on the device.

   ICX7150-24P Router# show license installed
   Unit License Name L3 Premium Port Speed Upgrade Speed Ports
   1    2X10G        No         Yes                10G   2
   

2. Enter the show version command to verify license details. The Current License field displays the license you have currently installed on the device.

   ===========================================================
   

3. Enter the license install perpetual command, followed by the unit number and the purchased license name.

   device# license install perpetual 1 4x10gr
   

   The example installs a perpetual 4X10GR license on unit 1.
4. Enter y to accept the End User License Agreement (EULA), or n to cancel.

   Continue?(enter 'y' to continue, 'n' to cancel): y
   

5. Confirm the license installation with the show license installed command.

   ICX7150-24P Router# show license installed
   Unit License Name L3 Premium Port Speed Upgrade Speed Ports
   1    4X10GR       Yes        Yes                10G   4
   2    2X10G        No         Yes                10G   2
   

   The example shows a 4X10GR license with Premium Layer 3 features is installed on unit 1, and a 2X10G license is installed on unit 2.
6. Enter the show version command for additional details to verify that the license is installed correctly.
