It would be a better option to pin point the solutions if you can provide the problems being faced by you. The issues one would experience in Windows 10 ( or any other OS for that matter) would depend upon many factors like the individual system, the apps that have been installed and so on. However, a few common problems being reported are as under -
1. Unable to upgrade from Windows 7 or 8
There are times when your Get Windows 10 app will notify that your PC is not compatible for the upgrade while you know for sure that it is. You may not get the app at all.
In such cases, run Windows Update to make sure your OS is completely up to date. Unhide the updates that you have hidden and install them. Ensure that Disable Execution Prevention is enabled in the BIOS.
2. Less free storage after upgrade
Maybe the previous version is still within your system. It will stay inside with the name Windows.old and take up a lot of space. It has been done so to help you just in case you want to revert to your old OS.
