im planning to upgrade 7 home 64bit to 10 home 64bit with the in place upgrade option. assuming this is successful will the install be stable? or should i just buy SSDs and do a clean install. i would use the same HDD set up i have now 2x2TB SSD drives. if i can avoid spending any money on this i will but if that isnt an option.........
Assuming it goes OK, it will be stable.
As with ANY major software or hardware upgrade, have a known good backkup and fallback plan before you start.
Where did your Win 7 license come from? This may impact how you do this.
If this was a prebuilt system, in place upgrade.
If a Wn 7 license that you bought, do a full wipe and reinstall, and then apply that WIn 7 license to activate the Win 10.
