筆記本上上使用的SSD硬盤，空間比較小，以前安裝visual studio占用空間比較大，后來直接使用官方的卸載工具，但是卻遺留了很多相關的組件無法卸載。今天實在無法忍受了，發現github上有一個軟件可以卸載，雖然軟件針對的版本比較老，但是使用確實可以卸載干凈，記錄一下。
下載TotalUninstaller.zip(https://github.com/Microsoft/VisualStudioUninstaller/releases)
解壓並用管理員方式運行Setup.forcedunstall.exe
鍵入“Y”卸載，卸載完成會自動關閉
由於本人筆記本積弊已久，安裝過多個版本的visual studio，多執行幾次就可以卸載完全了。
