Microsoft Reduces Windows Update Size

Since vista, lets say you have home premium and you want pro. All you need to do is open up, add new windows features. This will then take you to ms store where you can purchase pro. When you are done, windows just grabs a few pro features windows updates and it does not download the entire pro iso. So instead of spending at least 2 hours for the job to complete. It just took about 10 minutes. 

 

Isn't this almost similar to what they are doing now. 

No. That was the same OS, just adding new programs.

 

This isn't about adding new programs to the existing collection in the OS, it's about making the updates for those programs delivered in smaller packages.

 

So before say you add the hyper v hypervisor. That downloads full size. But now a windows update comes out for a file in it. What happens? The whole file has to be replaced. 2 bytes of a 20gb file change? Download the whole 20gb file all over. Obviously I'm exagurating to make the point more obvious but smaller files add up over time.

 

With Delta's, it just downloads those 2 bytes, and a hash of what the original file should look like. It then hashes the file on your system, makes sure the two hashes match, and if so just patches the original file with the 2 bytes of data. If they don't match up due to file corruption? It doesn't break the process, Windows update will just fall back to the old behavior and download the rest of the file.

This is going to lower the amount of internet i use.

Ironically you're clogging up the thread by quoting the entire OP.

So... when is MS giving us an option to choose which updates to install? The option that would benefit the user the most. I think it should actually be comimg soon iirc, read about that somewhere.

two changes in task scheduler and updates no longer reboost your machine.

Yeah they talked about this for some time. Long overdue kinda, even it's not some very important thing. But soon enough.

i could see this screwing up update systems for organizations who choose which updates to give to systems

something like this would require servers to have support for the new and old update systems

many organizations don't like using win10 (mainly because of not having a choice of what updates to install into the systems and privacy reasons cuse win10(enterprise doesn't have privacy problems), there are some things microsoft do right)

if you don't know what i'm talking about read this on TechNet, (microsoft's official documentation on their software)

https://technet.microsoft.com/en-us/library/hh852345(v=ws.11).aspx

it states:

Quote

The Windows Server Update Service (WSUS) enables information technology administrators to deploy the latest Microsoft product updates. By using WSUS, administrators can fully manage the distribution of updates that are released through Microsoft Update to computers in their network. 

this new form of WSUS could really do damage to some organizations systems, as they have designed it to their needs

i really hope microsoft won't force organizations to use this new system

Unless they're using LTSB then they'll likely have to use this system.

do you work as an IT admin?

because if you do you would know....

almost every organization uses an LTSB windows server OS for windows based workplaces!

no-one uses nano-server as it's not useful in most workplaces!

sorry...

i'm in a ranting mood...

didn't get fired or anything, it's one of those days...

(not those type of days woman get! god you perv!)

Home Premium does not have the features that's available in Professional, so how could I just be adding those programs when it's not even there in the first place. It's basically the same thing, instead of me downloading a 4GB ISO just to upgrade, all I had to do was download like a 100MB file and add that, where Home Premium changes to Professional. This function has been here for a long time, just that MS has decided to recently announce it recently. Windows 7 Service Pack 1 64bit comes in at 903.2MB. On a clean non SP1 install of Win7, after installing a bunch of windows updates, Windows 7 Service Pack 1 will only show up in Windows Update with a file size of just  aprox. 41MB, instead of the full 903.2MB.

Again, cumulative updates and delta updates are very different in implementation.  Traditional Windows updates have always been on a file level where delta updates are updates of only parts of files.

 

The reason why Service pack one is smaller in that case is because it doesn't have to bundle in those other updates as cumulative and only has to update the files which the service pack itself explicitly applies to. It still has to do an update of the whole files though, regardless of how much of them has actually changed.

 

Delta updates specifically allow it to download only *part* of any of those given files, further reducing the size.

 

And again, Windows 10 build upgrades, version feature "updates", and standard windows updates are all *very* different in implementation. The Windows 7 Service pack was of the third catagory. It was just a standard cumulative windows update.

 

Windows 10 builds are far more similar to say upgrading from vista to 7 than from 7 home to 7 pro.
