Is it important to update Microsoft software?

Is it really important to get the latest, greatest Microsoft operating systems and productivity software? Granted, with prices like these, it probably seems like a no-brainer. But there are plenty of extremely good reasons to keep your Microsoft software up-to-date.

For starters, most software gets better over time. Running the latest version of an operating system, and using the latest iterations of productivity software, ensures you can access all the hot new features. That typically means upgraded functionality and boosted productivity.

In addition to that, newer versions of software typically prove more secure. The patches and security upgrades eliminate vulnerabilities present in older versions.

Also, when you put off updating software, you can run into problems down the line. Microsoft eventually quits supporting older versions of its software. If you own newer versions, you won’t have to worry about losing access to tech support when a problem comes up. Most likely, you’ll prefer that to having to upgrade in the middle of a crisis.

Some details about your purchase

Keep in mind that CdkeySales.com’s licenses are not transferable. The software keys work for a single activation on a single computer, except where two PCs are noted. If you move to a different computer in less than a year, you must buy another license in order to continue using the software.

Considering the deep discounts you can currently get off CdkeySales’ already low prices, the restrictions above probably don’t seem like a big deal.

To get your 35% off discount, shop at CdkeySales.com and enter the discount code CULT at checkout.
