To remove Android OS, you can usually do it through the disk management tool in Windows. First, make sure you’ve backed up any important data. Then, open Disk Management (type diskmgmt.msc in the search bar). Find the partition where Android is installed, right-click on it, and select ‘Delete Volume’ or ‘Format’ if you want to erase everything. After that, you can resize your Windows partition by right-clicking on it and selecting ‘Extend Volume’. Just be careful not to delete or format the wrong partition! Hope this helps! Poor Bunny
