One thing for sure: any W7 that has been restored from W10 upgrade may sustain corruption to certain extent, and in serious cases, a reinstall is required
The safest method of experiencing W10 is to back up any existing W7 partition using ghost or similar methods...
This way, if even your restored W7 partition gets corrupted, you still have the clean ghost backup to use
Simply using the default system restore could be a very dangerous move |
