This Windows 10 can be a problem, I personally had to reinstall it 4 times. The first time I did an upgrade it ran good for a month then I noticed that my hard drive went from 31GB in use to 64GB and then unto 467GB in use, Not Good in my book. I have yet to have any issues with Windows 7 or even Windows 8 or 8.1, they ran good for me. back on track, I re-installed my Windows 8.1 with a clean install then upgraded back to Windows 10 Pro, the reason I had to do this was because I passed the 30 days and I could not revert back to Windows 8. After 3 weeks there was file corruption, bad again.
This last time I installed Windows 10 Pro, that I copied to my USB Drive, I formatted my drive 2 times to make sure it was clean, I then plugged in my USB and installed Windows 10 Pro however it did ask for the license code, I used the Windows 8.1 code numbers. Re-Installed Office 2007, Norton's 360, Fox Reader and last PC Matic. So far no issues to date, it has been 3 weeks and it is running smooth. However, I will say this, I had Windows XP Pro on this computer for over 12 years and never had an issue, during the course of those years I re-installed it 2 times with a mirror image from Ghost on a disk. this is what I will do again if it runs good for 3 months straight, that is create a mirror image with Ghost after cleaning, updating, defragmenting and finally check for viruses and spyware and last but not least check for file corruption (SFC / Scannow), If all good I will make the image, I do this because Windows claims that it will create a system image but it is not true or it has not work for me, it will repair or reset Windows only. I have 2 computers at home and 1 laptop, I tried to install on my second computer, after 3 days it all went south, thank goodness for Factory Reset Partitions.
while I have somebody's attention out there, thank you and good luck. Bandido
