title: How to uninstall GHCup and cabal after windows reinstallation
body: <p>Before reinstalling windows (both old and new are 10), I've run unins.exe file, but <strong>C:\Haskell_Platform</strong> folder was not deleted completely (<strong>C:\Haskell_Platform\cabal</strong> and <strong>C:\Haskell_Platform\ghcup-gho30eys.v5c</strong> 0.7 GB and 5.5 GB respectively) were still there. I thought that after windows installation they will be moved to windows.old folder, so I could delete them after, but they did not. So my question is may it possibly affect anything if I try to install HP again and if it is so, how to remove them properly?</p>
