Anybody upgraded to Windows 10 or bought a new device running the new OS? For almost a year I labored over a decision whether to upgrade our two laptops to Windows 10. Both were running fine so should you "fix it if it ain't broke"! But there are rave reviews of Win10 and it is free. A few days ago I finally updated my laptop (I was afraid to touch my wife's laptop!) The complete process from the time you click Upgrade until you have your computer back took about 4 hours! (You might want to let it run overnight.) So far all my applications work with Win10. I expected Word 2010 and Excel 2010 to work but wondered about a few non-Microsoft or non-major player softwares - like little utilities and handy programs from small software companies but they all work it seems. Win10 did break a few file extension associations (IE: I use Irfanview to open JPEGs and Win10 reset JPGs to be opened in MS Paint or whatever they call it today) but I was able to easily return to the file extension associations I wanted so no big deal. Otherwise I haven't had problems. I'm pleased with the speed of Win10. Web pages load noticeably faster in Firefox under Win10 than before with Win8.1. Also the new Microsoft Edge browser loads pages fast. It feels like I've upgraded the speed of my Internet service. Great upgrade for this reason alone. Since the update of our Win 8.1 Dell laptop went well I decided to go ahead and do the same to our Win 7 Toshiba laptop. After all, the price can't be beat (free)! My wife wasn't so sure but liked the way my laptop ran. Again, the complete process from the time you click Upgrade until you regain control of your computer took over 4 hours. The download itself is 4 gigabytes which took 2 hours using our 7.5 Mb/sec DSL but that would be much faster with a faster Internet provider. Actually the download took another hour because it failed about 5 times so I had to restart it repeatedly. Fortunately the successfully downloaded stub of the file remained intact on my hard drive and the download program found it so started off where it left off before (5%, 15%, 55%, 80% and 95%) instead of going back to 0% each restart.That was worrisome but the integrity of the spliced together installation file is verified before installation. Other than the new Microsoft Edge browser I haven't played with Cortana and other new features of Win10; I've mainly been concerned with proper function of existing applications that we use. I would say go ahead and take advantage of the free upgrade to Win10 which MS says will end around June 29th. I suspect that offer will be extended because MS wants to move most Win7&Win8 users to Win10. I didn't lose any files but backing up your personal data would be smart before the upgrade. Everything seems all right on both PCs so far, apps open and data seems ok. I did have some other minor problems on the second laptop, again broken file extension associations and this time the speakers were mute because Win 10 defaulted to the headphones jack instead of speakers (a simple fix in Control Panel). I'm pleased with Windows 10 but what really matters is that my wife is pleased, too, the second laptop is her computer! So far she likes it. Oh, anyone updating many computers would want to create an installation DVD to avoid multiple downloads of the 4GB file. Microsoft has an ISO image file you can download and burn to a blank DVD. (Or create an installation USB drive) I may do that just to have the DVD. They may sell a DVD too, I haven't checked that.
