I have some services that are always using the CPU and writing to my disk. Eventually they eat up all physical RAM, which causes the noticeable performance hit.
I can't find them in Services.msc, so tried doing sc config "UserDataSvc" start=disabled in an Administrator's prompt, but get the error:
[SC] OpenService FAILED 5: Access is denied.
They write non-stop, always, and restart themselves after being stopped. They probably write hundreds of GB to my SSD each day so I'd like to disable the services until the bugs are fixed.
I think the main culprit is UserDataSvc.
Here's a GIF showing how tough it is on my SSD after just 19 minutes:

I solved the problem by setting in the Registry the start value for these two fields from 3 (manual) to 4 (disable):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UnistoreSvc
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UserDataSvcThe Unistore Services belong to the Windows store. Looks like the store installs App-Updates. In the store option you can turn off the automatic update.
1After months of research I was able to permanently disable the entire UniStackSvc group, since Regedit would not allow and change its name! In the Regedit editor, browse to HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Services For example CDPUserSvc - the renaming will be with a numeric extension such as CDPUserSvc_26474 Go to the Start key and change it to 4 (do not load) Do this with all entries (+/- 14) Serve for other services that you. Does not want it to be loaded into memory. Only for professionals who know what they are doing! The Windows-10 was loading 120 services, now it runs fine with 80!
