I reinstalled my win7 PC yesterday and when I launched Nvidia Control Panel today and wanted to set profile for specific application, there were applications from previous installment visible (i had "Show only programs installed" checked). When I typed the name into Start and clicked "Open location" I got message it no longer exists.
What i did when reinstalling was as usual except I just removed all partitions (so the whole disk was unspecified space) and then ran installation on that.
Does this means that if there was virus in my previous installment could it survive (if we dont count specific cases of viruses who resides in MOBO's UEFI bios or something)? Also i did Avast/MalwareBytes check which found nothing before reinstallment but PC acted really strange. Could it be just some registry entries which survived or undeleted memory on disk which somehow gets read?
Thanks for any explanation/clarification.
Did you install Windows over itself or format the drive then installed Windows? Based on what is still on the HDD, it sounds like, you installed Windows over itself. – Ramhound – 2018-10-14T15:54:47.223
Yes, i installed windows over itself I guess. But it was booted from USB from BIOS not inside of windows. Also there is no sign of windows.old. Basically I thought it is gonna format in installation so I did not format it, only removed logicals to make it all unspecified space. Maybe it did fast formatting and now memory gets read from places where data chunks still resides? But then I dont understand why OS would try to read there. – eXPRESS – 2018-10-14T16:28:03.313
Your question is not clear. Please provide more specific information in order to better understand what you describe. This question cannot be answered without that information. – Ramhound – 2018-10-14T16:42:16.630
I think that harrymc basically summed it up in his answer. The question is if something non-windows could have survive this "upgrade". – eXPRESS – 2018-10-14T17:39:36.283
The answer you received is actually incorrect. If Windows "upgraded itself to itself" there actually would be a
Windows.old
directory. You indicated that the partitions were deleted, became unallocated space, and Windows was installed to that. Once you provided that information it was clear, you were originally not clear, one what data still exists on your system. Which is the reason, I requested more information, because what data still exists is not clear. Now your welcome to accept the answer you received, that is entirely up to you, but you should still improve the question. – Ramhound – 2018-10-14T23:23:44.410Hello Ramhound, sorry was out for some time, I do not fully understand what are you trying to say now. What is your idea of what happened then?
(I was checking and found really only references to programs from that nvidia and start panel, nothing more, all the actualy folders are missing if i try to follow up on that reference. No drivers no nothing was also avaiable after that reinstall. Really only thing which I found to persisted were those references.) – eXPRESS – 2018-10-17T15:01:12.070
"What is your idea of what happened then?" - I don't know which is the reason I requested you provide more information. If
Windows.old
does not exist then an in-place installation could not have happen. Likewise, an "in-placed upgrade" or "in-place repair" cannot be done from WinPE. Both of those can only happen if you start the installation process from within Windows. – Ramhound – 2018-10-17T16:07:44.520Then I am perplexed. I can't understand what happened then... – eXPRESS – 2018-10-18T18:02:28.550
