pcpunk, if you have CCleaner installed on the system, there's a Startup tab, that'll allow you to have more control over what fires up at boot. Easy to use, and just disable one or two at a time, reboot, make sure all is OK, disable more that you don't want at startup.
Yet don't disable any Windows services, and it's best to stay away from the Advanced checkbox, this is for those who truly know what they're doing.
It's kind of strange, I've found on most of my Windows 7 systems, that updating has been slow, probably because Microsoft made it that way. They want it's customers on Windows 10, they get priority, though well behind Windows 7 in usershare. Remember, it took Windows 7 over three years to overtake XP as KIng of OS's. One thing that you can do to help is open Services, just type it into the Start Menu, and restart Background Intelligent Transfer Service (BITS). You should also set the updates to download, but let you select when to install. This allows me to 'hide' any updates that'll try & force a Windows 10 upgrade, but actually I fixed that a long time ago, yet that takes some work & being very comfortable with what you're doing. There's many Telemetry updates, that 'phones home' a lot about the user, in addition to their 'Customer Experience Program' (believe it's commonly called 'CEIP'), all of this garbage can go, it's all Windows spyware working against the user. Even on Windows 7 & 8.1 this is true, as well as some components of Vista.
Yet one slip-up in the Advanced processes to remove these (some are actual scheduled Tasks), will cause a complete reinstall to be needed, or recovery from a system image restored (why I do my best to push backup).
Unfortunately I Opted for the whole package, because, well, didn't know exactly what came with them.
With printers, though you may need the included optical disc, don't open 'autorun', rather open the folders, as well as your Device Manager. When you see the printer show in the Device Manager, choose under Drivers to select to install your own. and point it to the CD. Over half of that included software is garbage that'll reduce startup times, and while one may think it's cool & all, much of it is borderline Malware. Don't take my word for it, scan the optical media with Malwarebytes & see for yourself. Or the unzipped downloaded driver package, never open these whole, 7zip is free for everyone. Once opened, the files are exposed for Malwarebytes to scan really good & I'll bet that some will be flagged & require a reboot to finish cleanup. Toolbars, coupon apps, shopping assistants within these packages are often considered as Malware (just ask anyone who knows, they'll tell you the same).
Not to mention loss of performance over the Start entries created. Like I stated, modern printers does not need a computer to perform many functions, especially copy & scan, and photo printing from an SDHC card. Though for the ones w/out an interface, one will be needed, still the photo app can be install w/out the garbage. Open the package & view the options, autoplay is the worst way to install a printer, by the time all is said & done, one will have an extra 8-12 apps installed.
