Hi, and thank you for asking your question.
This has been an issue acknowledged by Microsoft - it has to do with the huge number of users getting the Windows 10 upgrade right before the free period expired, clogging up the Microsoft updates' servers in the process. Please rest assured, two hours is not at all a significantly long time for it to get stuck at 99%; some users have reported it taking upto 10 hours to get from 99% to 100%. However, the upgrade will be completed all right - just leave it running overnight. If you do hard reboot your computer instead, it will roll back all of the changes and take you back to Windows 7.
If the upgrade is still stuck at this point after 12 hours or so, you just need to reply back to me on this page (you can get back to it anytime later on through your emails), and we will troubleshoot further; I'm 100% positive that the upgrade will be completed successfully by then, however.
If you need more help, please use the Reply box below to continue our conversation.

Ah, I see - you started the upgrade on 29/7. Please do this now:
Press and HOLD down the Power button on the laptop for atleast 30 seconds (even after the screen has turned off), and then release the button.
Next, press the Power button one more time to turn the laptop back on - what shows up now?
Do let me know.
Do update me on the issue when you can; thank you.
Hmm, okay. Now, please hold down the Power button one more time for 30 seconds, and then release the button. Next, press the Power button once again and tap down the F8 key repeatedly at bootup this time. Does it bring up a different screen now?
OK, do you see a "Safe Mode" option listed there?
OK, please select that option and press ENTER twice. Are you able to boot into Windows 7 all right in this mode?
Keep me posted.
OK, we will do a System Restore next, to roll your system back to a point before you started the Windows 10 upgrade. Please go to Start, type in system restore in the search field and press ENTER.
In the System Restore window, select "Choose a different restore point" (if listed) and click Next.
Next, TICK the "Show more restore points" checkbox (if listed) and then select a restore point dated BEFORE you started the Windows 10 upgrade. Click Next > Finish.
The restore process will take some time to complete, after which your system will be rolled back to before the Windows 10 upgrade was started. Please let me know if you are able to boot up normally thereafter; I'll be here.
That's all right; the first error is common when doing a System Restore and does not mean anything - the restore process did complete all right, and your system was rolled back to the point you selected (hence you were able to boot up normally now.)
Checking the second error now, just a moment.
OK, looks like a buggy/corrupt program is installed on your system that's showing up this error at startup. Please go to Start > Control Panel > Programs and Features > Uninstall a Program; do you see an Advanced System Care program listed?
If you don't see that listed, please check if you have any IOBIT program listed as well. Keep me posted.
OK, please go ahead and uninstall it first, and then restart your system and let me know if errors show up at startup this time.
Coming to your system, it's very likely that it got stuck at the Windows 10 upgrade process for longer than usual because it's a relatively old processor and so was not able to handle the already existing server issues to upgrade to Windows 10.
However, Windows 7 should function just fine for you from now on; do keep me posted on the results after it restarts - I'll be here.

No problem at all; thank you for getting back to me, and take care :)
