seemingly very common problem that affects the migration process from Windows Vista to Windows 7. The defect causes the upgrade to Windows 7 cases regularly until you achieve 62% of completion, Only to crash. The user is not nothing else to do but restart the PC and assist with a procedure rollback (fortunately successful) that restores the proper functioning of the previous operating system.

Microsoft has published an article (the KB975253) Which, besides explaining how to solve the unexpected in a manual, also presents a "Fix it"Or an automatic correction to be applied to Windows Vista before upgrading.

According to testimonies collected by the network, the script seems to be really effective. Microsoft recommends, however, to apply only in cases of genuine need, and only if the setup is exactly hold up to 62% of the total.
