Neemo's suggestion is worth a try; however you should know that Microsoft disallows any and all attempts to revert back to Win7 (or Win8x) from W10 after 30 days.
If you removed the hidden Windows.old directories (there can be up to 3 of them), you're out of luck anyway, but even if you had them backed up or sitting in your trash and restored them, you'd be over the 30 day limit and it's gonna be a "no-bueno" I'm afraid.
You might consider backing up any personal data you have on that computer now to external media, and use factory Recovery Discs that came with your computer when you bought it, or make them using a built-in Create Media app that comes on most modern computers (built after 2009), or use the built-in hidden factory Recovery Partition to do the same thing. This will wipe your hard drive clean (make sure to use the
CUSTOM option), and put back the factory load that came on the computer when it was
OOB condition (
Out-
Of-
Box) with all the original Win7 OS, apps, trialware, drivers, etc. etc. back onto the computer. In many cases such as Dell, Acer, Gateway, and Toshiba, you won't even need to re-enter your Windows license key, since it's built into the factory Recovery media. And there you go!
