glad to hear it 

try to use balanced on your power plan

try Process Explorer to observe which one suspicious

no w10 supports both.

btw you can always download the 1607 iso and apply upgrade yourself without waiting.

dont set auto backup, change to manual backup or if youre still want it to be auto then make sure the file keep on override the old one.

i think you did os upgrades instead of clean installs, without wiping all partitions. for clean installs with iso files downloaded from ms on a clean drive, you only get one recovery partition.

you can try use third party partition tools for this (acronis; macrium reflect; aomei; or others); but usually messing with these partitions is risky without knowing which recovery partition is currently linked to your os. you might end up wiping all partitions and doing a clean install.

Let me double check and PM you the step by step.

yeah with those upgrades there were many recovery partitions created.

you should try DellMalaysia's steps to see if it work first. if it's not working, you can try a clean install.

tbh it's not hard to perform a clean install. a lot of people failed because they don't prepare enough for the worst. also, the more you know about your computer the better. as long as you have backed all your data up, and have a working usb-based w10 installer. a working set of drivers are handy too, especially network-related drivers. the safest way to do it is to unplug all other data drives first, except the one housing os. if your system is a single-drive, then you can just proceed. the key thing to do during installation is to remove all partitions from your system drive first, and let the os installer to create new ones for you. (for the partition cleanup, the better way is to use diskpart; but this is only useful if you are familiar with command prompt) since your w10 already has digital entitlement because of upgrade you can skip any place that ask for product keys.

Not expert  but i like to google and reading from windows Microsoft forum. Already PM you.

yes, restores from system backups are much more convenient, provided that you have a copy of system backup created from a clean-installed os. (which is the cleanest, and the least problematic during restores; you can create one after driver installs and applying all tweaks)

are you restoring the system with a clean boot from w10 installer usb/dvd? by right you will not encounter such messages as something is in use if you boot from the w10 installer.

no wonder; that's how you failed to do it. as the message implied, you cannot do system recovery while still in windows. you need to boot the computer up with w10 installer disc/usb to proceed.

yes they were created by previous upgrades. (one at a time; for some reasons w10 doesn't reuse the existing recovery partition) this is also why i suggest clean installs instead of upgrades, because that's what you got when you did upgrades.

i am not familiar with restoring recovery partition properly sorry. i think it's possible but i have no idea how to do that.

officially, no. you missed it already.

however for some reasons, you can still activate w10 with old but legit keys. note that the risk is potential deactivation, because if you do it now the record in ms server will show that yours get activated after the valid free upgrade period.

alternatively, yeah, you can get it via the free upgrade program for customers who use assistive technologies. you don't get any product key. the upgrade is licensed via digital entitlement.

actually they are basically the same.

there are differences between the latest w10 and w10 anniversary update.  maybe that's why you have the impression that they are different.

the fastest and safest way to download w10 official isos is via ms.

maybe i'm not clear enough sorry; whether you get w10 upgrade via the previous w10 free upgrade program, or via the special free upgrade program for consumers that use assistive technologies, you get the same iso files. there is no special version for w10 with assistive technologies.

just download the normal version iso file will do
