After installing more apps withlive tiles i start to have probs with live tiles not working or updating..
I start digging the web for possible solution and i ended up at this site
This article was a relevation to me...
I learn a lot about the live tiles and that developers with bad apps can be the cose of the this problem...
So the short story :
If you have problem with live tiles then open the registry and check those 2 keys
Probably the Endpoint key has more that 20 entrys and the ManagedEndpoints arround 10 keys..
What i did to solve my live tile prob
1. I did disable the live update in all my apps.
2. I Delete all the keys in the Endpoints keys ans reboot my phone.
3. After that i start all the live till apps and re-enable the live tile ...
After 10 min boom!!!!!!!!! all my live tiles where working again...
I know that a lot of ppl have probs with live tiles so if anyone try this please report back your findings
Thanks again Jim Szymanski from Mobility Digest for this usefull info
Seems that if you delete the key HKLM\Software\Microsoft\PushClient\Endpoints its faster (than deleting one by one all the entrys)
and does the same job.
