Description:
The rollback feature remains activated by default. It can bring back the previous state of the system in case the installation gets failed. It takes lot of space. For this, go to start > run menu, enter regedit and navigate to the registry path listed below. If any of the subkeys \windows\installer does not exist, create it as explained below. Then, create a string value disablerollback in the right panel. Now, right-click and modify its value to 1 which can rollback feature. However, if you want to show the original options back, change the value data to 0 or delete the added value. The changes take effect after a restart or logoff. Note: experts must handle this feature only when it becomes very essential.
