I upgraded (not clean install) my laptop from Windows 7 to Windows 8 and now I have three problems. The first is that I can't delete the Windows.old folder. The second is that Disk use is 100% for an hour or so after startup and random spikes causing everything to respond slowly or stop responding. And last is that there are duplicate processes in task manager.
1. Can't delete Windows.old
I was trying to fix the performance issues, so I decided to do a disk clean up (with system files and everything checked) and had the drive defragmented. It made booting to the OS and shutting down much faster, but my second problem still persists.
I decided to uninstall unrelated programs, and tried disk cleanup again. This time though, I got stuck in Previous Windows Installation. It's weird since it was only about 16 Mb. I cancelled it since the progress bar showed no progress after 30 minutes or so. I Tried Step Two from this tutorial on deleting Windows.old, but I just got "The request could not be performed because of an IO device error" and something like insufficient rights errors. Also, every time something tries to access the Windows.old folder or any of its files, the disk usage spikes to 100% (with mostly the System process) and everything I do slows down and stops responding (same in safe mode boot). Is this a problem on my hard drive? What can I do to fix this?
2. 100% Disk use by System
I noticed that at startup the disk usage is 100%, I checked and I saw that it was the System process. I'm not sure, but I think this causes the slow response and no response from my laptop. I tried restarting in safe mode. It was still a bit slow (but much faster) and the random lags are still there (but tolerable) but I chan't check if it was still the disk use problem since the disk is not part of task manager in safe mode. Why is the system process eating up disk use? Is there a way to fix this?
3. Duplicate processes
I checked the details and there were duplicate processes. I saw 3 dllhost process 1 by the system and one by my user account, 7 from a vaio tool, all were from my user account (there was only 1 before the upgrade), and other duplicates. Why are there duplicates? Do I have to reinstall all the drivers and programs to fix this?
Sorry for the long explanations, I hope someone could help. Thanks!
