Windows 8 Vertical scroll won't stick

[borate]

W8.1. Vertical scroll with an MS 5000 wireless mouse is fine for weeks, then suddenly it's on steroids.\
Changing it in Mouse PROPERTIES (or the registry) returns speed to normal, but only until the next boot, when it reverts to fast.

Reinstalling MS Mouse and Keyboard Center software is a Link Removed - for a time. Then the scenario is repeated.

Clues as to why the setting doesn't "stick?"

Hi Borate,
apologies as it seems your post was missed. Did you still need some help with your issue?

Likely not missed - simply no answer. ^_^ Vert scroll has remained stable for a week, after MS Mouse/Keyboard Ctr reinstall.
I expect it will fail again - but for now, crossing fingers...

Thanks for checking in.
