not sure, but imo it should start when ms server has collected the hardware id of your computer during a successful upgrade. (which means last Friday)

as long as you do the downgrade within the 30-day period, it should be fine.

oh. a nice tip

no i didn't receive this update yet. maybe we should wait for a bit? from the internet, it's for those who did 1511 upgrade. https://support.microsoft.com/en-us/kb/3122947

i did a clean install.

ok nice

in terms of consumer space, there are not much difference from previous release versions. it's more like a maintenance release tbh. visually there are few changes. functionally, there are changes/improvements/enhancements in certain areas, but unless you use those areas frequently, you will notice nothing significant. for instance, if you're using bitlocker, 1511 uses 2 new encryption methods, 1 for fixed os/data drives (xts-aes; 128 and 256bit), 1 for removable or drives that you might wanna use in older versions of windows os (aes-cbc; 128 and 256bit).

imo the major thing in 1511 release is about enterprise space.

er don't see what around anymore? the cheapest path is free if your current os is qualified for upgrade (w7sp1 or w8.1).

The validity of free w10 upgrade is one year from last july, until july 29 2016.

why not just upgrade it with the offline method using tech bench iso?

not sure about your issue. mine is working fine.

try this? read all the pages, if possible: http://forums.windowscentral.com/windows-1...n-anything.html

did you try to use the manifest trick? http://www.danantonielli.com/adobe-app-sca...i-displays-fix/

this solved my issues with software applications that are not dpi-aware but tell the os that they are.

yes. you should have found out for now because if you click on the link and proceed with the steps, you will get to see the isos are named as Win10_1511_English_x32 or Win10_1511_English_x64.iso (which are essentially meaning 10586)

maybe you should confirm with the seller which windows version the key is for. (also, is it a retail or oem key?)

from your screenshot, it said activation server cannot be reached. (sometimes this happened because servers cannot be contacted by your computer) maybe you need to wait for a bit.

how did you run your iso file?

you can verify if the iso has the correct checksums:

1. download Microsoft File Checksum Integrity Verifier, https://www.microsoft.com/en-us/download/de...s.aspx?id=11533
2. select the file and right click to extract the files in a folder (eg. with 7zip/winrar). the program you need is called fciv.exe
3. put fciv.exe and your iso in the same directory
4. press shift key + right click in that directory in file explorer, and from the popup select 'open command windows here'
5. type fciv -md5 iso.filename and press enter key. wait until the calculation completes, the md5 checksum for your iso file will appear
6. compare it with the following:

91fad72bb84ee259cdb1772b2ce42375 *w10_1511_en_x32.iso
a0d4271b7537732a060909fd39d54829 *w10_1511_en_x64.iso

if it matches, your iso file is good. if not, download again.
